Logical Data Recovery on Mac OS X

When you need to get your lost files back, you will have to use a data recovery software which is supportive to the combination of your operating system and file system. All of the computer operating systems have different data structures; file system and data storage management mechanisms.

Mac operating system uses HFS, HFS+, HFSX, HFS Wrapper file systems. There is no set method of data recovery on any of the operating system. The data recovery software could be the same for different data loss cases of one operating system but the features, which you need to use, may be different according to the reason of data loss.

If you are facing the data loss problem with your Mac system and want to get all your data back, the first step to take is the selection of an effective and powerful Mac data recovery software. There is a wide range of data recovery software for Mac available in the market.

All of these Mac recovery software have a unique set of features and come with different price tags. An intensive scan of the affected hard drive is really significant to completely recover all of the data from the hard drive. You should go for a data recovery Mac software which is capable of performing the same in an effective fashion. Having an easy to use and simple user interface is also the must for a Mac data recovery software.

The Mac recovery software, you are going to opt for, must be simple enough to use without having any prior technical knowledge. The last and the most important thing that you should look for in a Mac recovery software is the file system and the file version support. The software should support all the file versions and file systems which are usable in Mac. After selecting an appropriate data recovery Mac software,

The next step is to find a healthy Mac computer, to install and run the software in it because installing the software on the same computer could make the data irretrievable. After installing the Mac data recovery software, attach the affected hard drive to it and scan it to end up with absolute data recovery.

Mac Hard Drive Failed to Mount

Sometimes you may find that your external hard drive mysteriously gets un-mounted by your Mac. All this happens suddenly and
may leave all of your data inaccessible. In this case, you won’t hear any strange sound from your hard drive which means that the hard drive is physically intact.

When you plug the drive into the port, you may get any of the following error messages:

“Mount: wrong FS type, bad option, bad superblock on /dev/hdb1,
Missing codepage or other error
In some cases useful info is found in syslog- try dmesg tail or so”


“Unknown device”

It gives two options to “Initialize” the drive or “cancel”

As the first error message suggests, the problem has occurred due to the File System errors, Super block corruption or due to any system file or directory deletion. It is a grave situation for the business owner or general home user to lose the precious and significant data.

It could lead to several catastrophic problems and in most possible case- the business destruction. In order to save your business, recovering the lost data becomes the need of hour. It can’t be eliminated. The data recovery is the process of getting your lost data back using special tools called data recovery software for mac.

The data recovery software which are usable in this particular case are known as Mac data recovery software. These are the powerful third party applications specially designed to recover your lost data from the affected Mac hard drive.

Mac recovery software provide complete data recovery Mac solutions and they are powerful enough to recover lost data in all of the cases. These software are very easy to use and don’t require high technical skills to perform data recovery Mac.

Data recovery Mac software is very easy to use and has an interactive user interface with rich graphical support to provide easy and quick Mac data recovery. The powerful scanning algorithms are used by the Mac recovery software to perform in-depth scan of the affected hard drive and perform absolute Mac recovery.

Removing ‘etc’ and ‘var’ Directories in Mac OS X Causes Mac Data Loss

When attempting to start up Mac OS X, you may come across one or more of the following symptoms:

Your Mac stops responding during startup
Setup Assistant rematerializes
BSD (Berkeley Software Distribution) commands which access files in var and etc fail

A message box appears with the message which contains: “/etc/master.passwd: no such file or directory.”

After any of these situations, you Mac refuses to start and you can’t access any of the data stored on your hard drive. The possible reason of this behavior is the deletion of “etc” and “var” directories. These directories appear when you start your Mac and they should not be removed for proper working of your system.

Etc- It contains all of the configuration files of your Mac system including both scripts for actually performing several tasks as well as documents specifying the configuration information. It is the most important data structure file which is used by the HFS series of file systems.

Var- This is the system directory which stores variables and library files produced by the Mac operating system to control the processes. It also stores a fair bit of the configuration information.

After deletion of these directories, Mac operating system won’t be able to retrieve the required files to start the operating system and will refuse to boot up. To work around this issue, you need to install a fresh copy of both these directories which is possible by formatting the drive and reinstalling the operating system.

Though this method solves the issue and it won’t occur in future but also wipes the data stored on the hard drive and leads to the possible data loss problems. During formatting of the hard drive, all of the data stored on it will be removed. It is the most critical situation for a Mac user which requires Mac data recovery to get all the data back.

Mac data recovery is feasible through the use of Mac data recovery software which are capable of scanning the drive and retrieving data and information from it.

Disk Initialization in Mac OS X

Disk Initialization is the process of making a hard disk drive usable. This process is generally followed with the new hard disk before installing an operating system. In Macintosh computers, it has there independent steps:

Disk formatting
Disk verification
Disk zeroing

After initialization, the disk becomes usable and you can install a fresh operating system on it and can use it. There are some situations, where you need to initialize a disk due to some system problems. These situations include if the directory structure of the disk has damaged and the disk can’t be accessed in its current situation.

It can also occur if the operating system has some problems and your system randomly freezes. Unfortunately, if any of these situations occurs, you need to initialize the disk. It can be done with the help of Disk Initialization Manager. It is the part of Mac operating system that lets you erase all of the contents of the hard drive.

It gives a standard user interface to initialize and naming the disk. Disk initialization is a very easy process and can be performed effectively with the help of Disk Initialization Manager. You can do it without having any sound technical knowledge and very quickly and efficiently.

After successfully completing the Disk Initialization, you will get a disk free from any problems or errors. It is correct that disk initialization will fix all of your system related issues. But, have you ever thought about the other side of the coin?

You most precious data stored on the hard disk will be wiped out with the errors of the hard drive and you will have a disk without your data. It is a very catastrophic situation for the user. It will cause the serious nightmare of data loss. In such circumstances, the recovery of the lost data becomes a very important task to save you and your business.

If the lost data is business critical then recovery should be performed as soon as possible. But there is no need to worry about your lost data. You can get your data back very easily with the help of data recovery software Mac. Data recovery software are the applications that are specially designed to meet the data recovery requirements of different users.

For Mac computers, these data recovery software are known as Mac data recovery software. There may be a wide variety of Mac data recovery software existing in the market but selecting the appropriate one is very important.

when the Disk utility fails- The volume 'Macintosh HD' needs to be repaired Error

While using the Logic studio on your Mac OS X, there occurred an error and the Logic studio application crashed. Thereafter, the colored wheel appeared on the screen and the system almost hangs out there unusually for several minutes. You rebooted the system and found the blank grey screen with a flashing question mark.

You plugged out the peripherals, such as external sound cards, printer, external modem etc and rebooted the system to find the flashing question mark again. All your data lies inside the Mac hard drive and the problem occurred so suddenly that you are quite clueless about the issue and have to think for some Mac recovery utility to recover back the data.

To your dismay, in the above situation, if you try to reboot your Mac system from the installation disk and try 'First Aid' from the Disk Utility in order to verify and repair, you may find the following errors subsequently:

'Verify and repair volume 'Macintosh HD'

the disk 'Macintosh HD' could not be unmounted”

“The volume 'Macintosh HD' needs to be repaired

Error:filesystem verify or repair failed”


Before cursing negligence and any such things, you must admit that there can be a number of reasons behind the issue, that you can count. It can be a bad RAM, bad sectors on the hard drive etc. Moreover, a system or application crash can sometimes corrupt the nvram or affect the journal or directory entries of the file system.


1. Try resetting the nvram and reselect the startup volume. The procedure changes certain system preferences like system volume, mouse speed settings etc.

2. If the the above measure fails and the Disk utility couldn't resolve the issue, then you are left with one choice to reinstall the operating system with the option Archive & Install.

3. If the the above also fails, it is the Erase & Install option that you have to opt for.

The Erase & Install option will wipe all the data from your Mac hard drive and you have to recover it from the backup. If you have not taken backup for for all your data or failed to restore from backup, then using a Data Recovery software Mac can do the better recovery.

Apple MacBook Air Data Recovery

Apple has MacBook air was introduced in January 2008 with high performance and speed. This was latest laptop from Apple in the MacBook family. It is the thinnest laptop of the world. It is based on mobile technology and has a unique hardware configuration:

Operating System- Mac OS X 10.5 Leopard

Hard Drive- 80 GB Seagate hard drive with 5200 RPM speed

Processor- Intel Core 2 Duo

RAM- 2000 MB

According to the hardware configuration in this release, the system works very fine. Like other systems, there are some problems with this MacBook air also. The main problem is freezing and crashing of the system. Sometimes it freezes after a regular time interval of 10 to 15 seconds.

It shuts down the CPU core and the problem generally occurs due to overheating of the system. The problem occurs when your run two or more programs at the same time. In these situations, the system may crash. Often, this problem occurs due to software reasons when you run more application at the same time, especially Xslimmer.

The problem may also occur due to some kind of hardware problem. When this problem occurs, you have to force the system to restart. In this case, your operating system may get corrupted or the data stored on your MacBook Air hard drive may become inaccessible. To resolve this issue, you need to format your hard drive and reinstall the operating system.

You should reinstall the application programs also. But reinstalling the hard drive is never safe as it requires formatting the primary volume of your hard disk. In this situation, things can go wrong and you may loose your important and precious data.

This situation occurs, generally when you have stored the important data on the primary volume or you haven’t partitioned the hard drive. It can create very serious problems for you and can put you in fix. But there is no need to worry about all these data. The data is still present on your computer hard drive and you can recover these data with the help of Laptop data Recovery Mac software solutions.

For Mac computers, this solution is called Mac data recovery software. Macintosh data recovery software also called Apple Recovery software are the application programs specially designed to recover the lost data from Mac computers. These software can help you in almost all possible cases of data loss including hard drive formatting, accidental deletion, operating system corruption and virus attack.

While Using Boot Camp Deleted Mac OS X Volume

Boot Camp is the utility in Mac OS X which assists Mac OS X users in creating a partition and installing Windows on Intel-based Macintosh computers. Although it is designed for non-destructive repartitioning of hard disk, but sometimes it might work different from what is expected. According to many Mac OS X users, Boot Camp has often been found to corrupt or delete Mac OS X partitions, making it impossible to access the data by normal means.

Running fsck or Disk Utility doesn't bring any affect and thus the only option left with the users is to recreate the lost partition. Doing so can no doubt is a suitable workaround of this problem, but data restoration is possible only if you have a valid data backup in place or use a Mac Recovery Software. After a general description, here is a specific problem that narrow downs this issue.

Suppose you as a Mac OS X user uses Boot Camp to create a Windows partition. After the installation is successfully done, when you view Mac OS X partition(s), they appear to be missing. More specifically, just a single partitions that doesn't correspond to any of the existing partitions. You can try solving the issue using 'Disk Utility' and/or 'fsck'.

Also, booting up the computer while holding the option key might help.Reportedly, many Mac OS X user cannot view their partitions on trying to install a Windows version that Boot Camp doesn't support. Most of these problems have been reported when Windows XP SP1 is even tried to be installed. Service Pack of Windows XP is not supported by Boot Camp, so you should instead try to install Windows XP SP2 or later.

This is the case of partition map corruption, so the prime solution to make your Mac workable is to recreate the lost partitions and restore from backup. In cases, when you cannot restore from backup, running a Mac File Recovery utility can aid in recovering all lost files and folders. Mac Recovery Software are exclusive products that can scan your crashed Mac drive and recover all the possible information safely.

Tips to Solve Blue Screen at Startup in Mac OS X 10.6

Blue screen error is one of the most common error among Mac users.What can be more frustrating than finding your Snow Leopard not starting up. Instead of the Finder, a blue screen appears and you have no access to important data that you want to access. No doubt, the situation is annoying, but it can turn to be a simple problem if you apply some Mac Recovery fixes to make your Mac bootable. Before coming to the solutions, let's consider a scenario depicting the discussed problem.

When you try to start your Mac OS X 10.6 Snow Leopard computer, you might find it not starting up. A blank blue screen displays and no further startup process seems to occur. In place of blank blue screen, you may also see a blue screen with a colored pinwheel. Since the boot process doesn't proceed, you have no data access. Most of such problems occur because there lie few corrupted or incompatibile applications or startup items that might be preventing your Mac OS X 10.6 Snow Leopard to start.

This same issue has also been observed that if you try to boot your Mac OS X 10.6 Snow Leopard computer from a DVD of another Mac model.In order to resolve the above issue, you should try the following steps:

You should try starting your computer in safe mode. If this works, you can choose Apple menu and then Restart to see whether the computer will restart normally

You can analyze it as the problem due to incompatibile login items if the startup doesn't proceed in spite of that login window asks for a user name and password. You need to remove such login items.

You should start your Mac from its installation disc and use Disk Utility to repair the disk

permissions and startup disk.

If all the above measures fail, the last resort is to use installation disc to reinstall Mac OS X and restore the data from backup.

In case of backup unavailability, you need a Mac File Recovery utility. A Mac Recovery software can help you recovering lost files and folders after any type of logical crash with Mac systems.In this way you will able to save your data and files from disaster.

Mac Journal Corruption and Recovery

In Apple Mac OS X journalizing is the process in which files can protected from any unexpected power outage. The journal keeps all the vital information that Mac computer requires to get back to a previous working state. Serious consequences can result if journal gets corrupted. For instance, it can make a volume unmountable, while rendering the data inaccessible.

We know that keeping a valid backup is an excellent way to prevent data from any lost, either if the backup is not available we can try Mac Recovery. The reason is that you can then safely erase the corrupted volume without fearing of any data loss. HFS Plus is a journaled file system and is thus susceptible to above discussed problems. Below is an error message that can occur in system log of a Mac OS X computer when a HFS Plus volume is corrupted:

Journal corruption usually damage the Mac volume to an extent that it cannot be repaired by Mac OS X built-in utilities. These include the 'Disk Utility' and its command-line utility- fsck. So you must adopt some other methods of Mac Data Recovery.

You can try resolving the given problem by disabling journaling and then re-enabling it again. If you have a backup from which full data recovery is possible, erase the corrupted volume and restore.

It would be more efficient to use a Mac Recovery utility to scan, locate, and recover the lost data. These are easily available products with competency to restore lost or deleted information from Mac disks. Due to their interactive nature, these programs can even be operated by a novice.

Solving Hard Drive Errors in Mac OS X Using Mac File Recovery Software

Are hard drive and file system errors preventing your Mac OS X computer from starting? Are you unable to access your precious data from Mac OS X hard drive due to hard drive errors? Well, this behavior occurs if your drive is damaged or corrupt. Power interruption, forced reboot, and unexpected system shutdown are major reasons of such kind of problems. Most of such issues can be fixed using the Disk Utility tool. However, if it does not work, you need to opt for Mac recovery solutions to get your precious data recovered.

The Mac hard drive errors may occur while performing typical computing operations, like accessing a volume, verifying a volume, opening any application, or mounting a Mac OS X hard drive volume. Such errors generally include the cause of the error and possible fix that you can help you resolve it. Some of the most frequent hard drive errors in Mac OS X are as
given below:

• file system dirty, run fsck.
• The disk cannot be accessed because a disk error occurred
• Attempting to copy to the disk failed. The disk could not be read from or written to.
• Firmware update failure. Disk write error.
• The Disk cannot be partitioned because some files cannot be moved.

Back up the disk and use Disk Utility to format it as a Single Mac OS
Extende(Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.

• Error detected (-9972) while verifying/repairing volume disk0s2 Macintosh HD When it occurs, the disk becomes totally unusable. To retrieve data from such disks, you must figure out the cause of this behavior and carry out data recovery Mac by fixing it.


The problem generally occurs due to missing, corrupt, or damaged data structures of Mac OS X hard drive. Corruption may occur due to virus infection, improper system shutdown, user errors, and more.


Use Disk Utility or fsck tool to check the integrity and consistency of problem hard drive. If it fails to work, Mac recovery software come to your rescue. These are third-party tools, which thoroughly scan entire hard drive and extract all lost data from it. The Mac file recovery program offers assured recovery in all logical data loss cases.

Disk Utility Live Verification Fails on Unmountable Mac OS X Volumes

Hard drive inconsistency and integrity problems are very common in Mac OS X operating system. To handle such problems up to an extent, Mac OS X operating system provides you an inbuilt tool, called Disk Utility. It verifies your hard drive and repairs the damages in some situations. The utility can be run from boot disk of Mac OS X operating system. You can run this program even on the live hard drive. This process is known as Live Verification.

However, in some situations, Live Verification of Mac hard drive may cause serious problems that lead to hard drive failure and data loss. At this point of time, you need to go for Mac Data Recovery solutions, if there is no valid backup in place.

You should keep the below things in mind while performing a Live Verification of Mac OS X had drive:

• The Live Verification works only on Journaled volumes of HFS+ file system. If you try it on non-journaled volumes, you may get an error message stating: “ERROR: could not freeze volume (Operation not supported).”

• The progress indicator of Disk Utility might stop advancing, applications may become unresponsive or work slow, or your system may freeze during Live Verification.

• Once you initialize the Live Verification process, you may not abort it.

• You may come across some problem when you attempt to repair or verify a unmountable Mac volume.

What happens when you run Live Verification on unmountable Mac volume?

Disk Utility program may freeze without showing any error, or stall the machine for few minutes, while repairing or verifying the unmountable volume.

When you attempt to verify a non-startup volume and Disk Utility cannot unmount it for any reason, verification process may start, but and may stop without any error.

After this behavior of Disk Utility and your Mac OS X system, the drive remains in inconsistent and damaged state. You cannot access data from such drive and need to perform Data Recovery Mac by resolving this issue.

You can easily recover your valuable data using Mac recovery software as they have interactive graphical user interface. The Mac data recovery applications employ high-end scanning techniques to thoroughly scan entire hard drive and extract all lost data from it.

Stellar Phoenix Macintosh Data Recovery is the most efficient and comprehensive utility that ensures absolute recovery in all data loss scenarios. The software safely recovers lost data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. It is usable with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.

Catalog File Corruption and Mac OS X Error

Like every operating system Mac OS X-based hard disk is also divided into different volumes. Each volume is comprised of four basic items: files, file threads, directories and directory threads. To define these items, Mac volumes keep their records in the form of catalog file. This catalog file is structured in B*-tree formation. Thus to locate a file or directory, system has to traverse whole catalog B*-tree.

But sometimes, this tree or its nodes can suffer issues, which may require reformatting the volume. In such cases, you are suggested to take full data backup so as to restore it later. In case of backup faults, Mac Recovery solutions are required. User may observe an error with Mac volumes:

“Invalid B-tree node size”

This error is observed with Hierarchical file system based volumes while verifying its integrity using Disk Utility. Damaged volume fails to be repaired using Disk Utility. The error is encountered if node size of B-tree is not correct. Note: The allowed size for records in HFS Catalog file is 512 bytes and in HFS Plus Catalog file is 8 KB.

To resolve the issue, you can try these solutions:

Disk Utility fails to correct invalid node size of B-tree. Thus, you can run fsck. It should be used in single user mode.

You can also use third-party disk repair applications. Such applications can cause more damages, so it is suggested to maintain a copy of all data, prior to use these applications.

If problem remains the same, you can backup all important data and perform clean reinstallation of Mac OS X. It can be carried out using Erase and Install option. Also, data backup must be valid enough to offer complete restoration.

Thus after backup process, the log reports and media must be checked. If data backup proves invalid to give required files, you can use commercial Data Recovery Mac tools. Mac Recovery applications scan media, in question, and recover lost data. These software products offer safe recovery with advanced searching options.

The procedures are safe. Such applications perform suitable file searching processes, irrespective of file system metadata. Thus, you can use these tools in any case logical data loss case. Macintosh Data Recovery is advanced Data Recovery Mac software for HFS, HFS+, HFSX, HFS Wrapper and FAT file system based disks. It uses influential and secure scanning algorithms.

HFS+ File System Corruption and Recovery

Mac OS X has a number file types like HFS, HFS+, and HFSX, among all HFS+ is the improved version of Mac OS Standard, HFS. HFS Plus volumes are comprised of different metadata structure information like Volume Header, Catalog File, and Allocation File etc., defined on their various sectors. Volume Header is the replacement of Master Directory Block of HFS volumes and stores volume metadata.

But due to corruption or inconsistencies in one or more metadata information, HFS+ volumes may get damaged. In such cases, data gets inaccessible and hence users may require HFS Data Recovery tools to recover (if data backup is unavailable, incomplete or damaged). As a scenario, when Mac OS X users attempt to boot the system or access one of the HFS Plus partition, an error is encountered:

“HFS+ partition Error”

This error is generally observed on dual-boot systems, more often with GRUB. System fails to boot when the affected volume is startup volume.

To solve this partition error, users can follow up given solutions:

User can use fsck and Disk Utility to repair the damaged volume

If GRUB is creating issue, user can check for its correct installation

If problem persists, partitioning scheme can be the concern. HFS Plus partitions use APM (Apple Partition Map) as their partitioning scheme. Particularly, incorrect starting sector number (odd number) of partition can create such errors.

Thus, it is required to repartition the disk and restore data from recent backup. If data backup is unavailable or incomplete, HFS Recovery applications come as rescue to recover lost information.

These applications search the affected drive for lost data and restore it securely. Mac Recovery software are the specialized tools to scan the drives and recover lost information. These applications make file system and operating system level scanning. Upon finding lost files, these solutions recover them.

Most of these applications come with interactive user interface, enriched with graphic tools and options. Hence, irrespective of any level of technical background, users can use them quite easily. These software products are safe to be used because of read-only design they possess.

When Using Safe Mode Mac System Goes Down

Mac OS X users usually know that it offer a special troubleshooting mode called Safe Mode in which system can be started up. Starting Mac OS X in Safe Mode compels directory check, disables fonts, loads only necessary kernel extensions, disables login and startup items and performs other such functions which help resolving system issues.

An automated check and repair happens when we start system in Safe Mode. If Safe Mode fails to solve the system issue, we may need to reinstall operating system. So data must be backed up. If backup fails, Mac Data Recovery will be required. Sometimes, it is observed that when user starts the system in Safe Mode, it may not behave as expected.

The computer may shut down with a gray screen and Apple logo. This specifically happens in Mac OS X 10.4 and later versions when system fails to repair the intended issues of hard disk. This is to protect against data loss which can occur due to further damage. However, we can deploy other alternatives to solve the system issues:

We can use Mac OS X installation disc to use Disk Utility so as to repair the drive. A third party disk utility can also be used for disk repairing purpose. It is recommended to check for version compatibility with Mac OS X to avoid further issues. Last alternative could be reinstalling the operating system using Erase and Install method.

As this process deletes all the data from hard drive, so it is must to backup data so as to restore it later. Backup failure creates Mac Recovery needs. Data Recovery Mac will be required if backup fails to offer complete required files or due to any cause, media gets damaged. Mac Recovery is accomplishable through specific applications which are designed to use powerful scanning algorithms and recover lost data.

Data Recovery Mac software have interactive interface and safely restore the lost information. Macintosh Data Recovery is excellent Mac Data Recovery software to retrieve lost data and safely restore it. The application can be used for Mac Recovery for HFS, HFS+, HFSX, HFS Wrapper and FAT file systems.

Interactive interface and quality data restoration procedure make this Data Recovery Mac software best. This universal binary application can be used with Mac OS X 10.3.9 and latest version including Mac 10.6 (Snow Leopard).

Time Machine Backup Incomplete on External hard Drive and Data Loss in Mac

Time Machine is in-build application provided by Apple to backup data from time to time.. The tool can carry out incremental backups of files on internal as well as external hard drives and hence helps avoiding Mac Data Recovery needs. In order to backup data to external hard drive, it is required that hard drive must be formatted with HFS+ file system with journaling enabled.

However, if the hard drive uses MBR (Master Boot Record) partition type, issues may occur. External hard drives, using MBR partition type, don’t support data more than 10 GB with Mac backup utility. So, if Time Machine is being used to backup data on such hard drives, the process may stop after 10 GB. If data gets lost after the external hard drive has stopped backing up data, then it can’t be used to extract lost information.

In such cases, we will have to use Mac Recovery applications. In order to make external hard drive to correctly backup data, we need to change partition type of drive as Time Machine compatible and hence format it. It is required to backup all the important data on some different location. However, if data gets lost from Mac system and backup is incomplete or issue occurs with the backup media

We can use Data Recovery Mac software. We can use Disk Utility to change the partition type of disk. We need to specify the desired number of partitions and select new partition scheme, which should be Apple Partition Map for PowerPC Mac and GUID scheme for Intel Mac. After this, we can set the disk again in Time Machine preferences to backup data.If the external backup media faces some issues or backup comes out to be incomplete, Mac Data Recovery software can be used to extract lost data.

Mac Recovery software are the specialized utilities to scan, locate and recover lost data using powerful algorithms. Macintosh Data Recovery is the best Data Recovery Mac software which uses effective and safe scanning algorithms. It supports HFS, HFS+, HFSX, HFS Wrapper and FAT file systems.

The application offers Mac Data Recovery for all the documents, images, music folders and application files. This universal binary Mac Recovery software can be used for Mac OS X 10.3.9 and above including Mac OS X 10.6.(Snow Leopard).

Apple has introduced a low cost version called iMac in its range of desktop computers. This desktop is very easy to use and latest features embedded in it, iMac has been designed to target all the office and home users. iMac comes in four models: iMac G3, iMac G4, iMac G5 and iMac (Intel-based). These models differ in design with major changes in outer looks. iMac G5 uses the PowerPC chip architecture. Other design specifications include 10/100BASE-T Ethernet port, V.92 modem, serial ATA hard drive, video-out port and others.

But, sometimes, this is observed that iMac G5 stops responding at startup. The issue may lie in operating system, for which OS reinstallation and hence Mac Data Recovery can be required. Other problems include problematic external devices and hard drive issues.In order to see if it is not an external device problem, we need to first disconnect all of them including FireWire, Ethernet, mouse, keyboard and USB.

Then, we need to reconnect these devices one at a time and restart the computer system. If system stops responding only after connecting a specific device, then we need to replace the device. The issue can also be of corresponding cable. So we need to check for cable problem also and replace it. Another issue could be corrupt software. So we need to start the system using Software Install and Restore disc.

If system starts normally, then the issue is damaged software and we need to reinstall the operating system to get the fresh copy of software using Archive and Install method. If the issue still persists or hard disk is not visible while installing Mac OS X, the hard disk may have gone corrupt.

We can use Disk Utility or reformat the hard disk and recover the lost data using backup or Mac Recovery software. We can also use third-party Drive Utility to reformat the hard disk, if it is not visible even in Disk Utility. However, if the hard drive is still undetectable, we need to replace it as the issue can be physical. But, before that we need to extract data by availing Data Recovery Mac service .

Mac Recovery software are the scanning utilities for formatted hard disks which extract lost data, maintaining data integrity. However, under Mac Data Recovery service, the physically failed hard drive is repaired and lost data is extracted using advanced tools and techniques.

This Mac Recovery software is compatible with HFS, HFS+, HFSX and HFS Wrapper file systems. Phoenix Mac Data Recovery supports all Mac OS X 10.3.9 and above versions. Stellar also offers safe Mac Recovery service through Class 100 Clean Rooms, where experts extract lost data using appropriate tools and procedures.

iTunes Store Shared Folder Missing Issues

In Mac OS X apple provides us music player called iTunes which is a digital media player application. The application is available for both Macintosh and Windows operating systems. Using iTunes, we can play and organize digital music and video files on CDs, synchronize with iPod and iPhone. iTunes Store is the online digital media store and facilitates online music sales.

This facility acts like a music vendor. In Mac systems it is observed that the user becomes unable to make purchases from iTunes Store or an alert is encountered which describes that some required directory is either missing or has some permission issues:
“There was an error storing your authorization information on this computer. The required directory was not found or has a permission error”User may also fail to play music which has been purchased from iTunes Store. These issues arise because of the reason that Shared folder is found to be missing.

Shared Folder gives the ability to share the music with other accounts of computer system. Its default location is /Users/Shared.

In order to resolve the specified issues, we need to recreate the missing Shared Folder:

We can make use of Finder application to find the missing folder. We need to choose Go menu and then Got to Folder, type “/Users” and Click Go. Upon finding the Shared folder, we need to check the Ownership and Permission settings by clicking File->Get Info and then clicking disclosure triangle. They should be set to Read & Write in all three Owners, Group and Others sections.

However, if no folder exists in the Users folder, we can create a new and set its apt permissions. Alternatively, we can also use Terminal application to modify the permission settings through commands. But, this is recommended to use these commands, only when they are well known as incorrect commands may result data loss or unusable operating systems and create Mac Recovery needs.

We need to use sudo mkdir -p /Users/Shared command, press Return, enter administrator account password, press Return, type sudo chmod 777 /Users/Shared command and then again press Return. However in any case, data gets lost due to incorrect commands, we can use Mac Data Recovery software to extract lost data.Data Recovery Mac applications are graphically rich utilities which can scan and recover lost information and restore them safely.

Mac Data Recovery software use powerful scanning algorithms which extract data, maintaining the data integrity. For effective Mac Recovery, this is advised not to install the software on the same hard drive, from which data has got lost.Mac Data Recovery software supports Mac OS X 10.3.9 and above and is compatible to be used with disks having HFS, HFS+, HFSX and HFS Wrapper file systems.

Mac OS X FileVault Space Reclaiming Error

Apple has provided Mac OS X with facility of encrypting information in home folder through FileVault, which helps in protecting the files. The application uses Advanced Encryption Standard algorithm to encrypt the home directory and the encrypted file system is mounted and unmounted as the user logs in and out of the Mac computer system.

Thus the Mac system can avoid Mac Data Recovery needs because with encryption done, accidental deletion and sabotage like cases decrease to an extent.FileVault creates a separate volume for the home folder before encrypting its contents. Before the system may sleep, restart or shut down, the system asks to reclaim the space. This process is a necessary part of the whole encryption procedure.

But, the problem may arise if after reclaiming the space, users lose some preference settings. Preference settings are the user specific settings for the system and applications. The customizations done in this way are done are store as .plist files. So losing them is not taken for good. In order to avoid losing preference settings as an effect of space reclaiming through FileVault, we need to install Mac OS X 10.3.1 and the later updates, which are free from these issues.

However, we can also turn off FileVault in the security or Account preferences. This should be taken care of that while FileVault is reclaiming the disk space, the system should not be restarted or else major data loss can be encountered. Unexpected power loss while the same process also contributes to create Mac Recovery needs. Data lost in this way is however recoverable through Data Recovery Mac utilities.

Mac Recovery software can scan and recover the lost information and then restore it at the safe location. Data Recovery Mac software are special tools to extract the lost information through a set of algorithms. This is recommended not to install Mac Data Recovery software on the affected hard drive so as to avoid permanent data loss due to overwriting.

Mac File Recovery is feasible for FAT, HFS, HFSX, HFS+ and HFS Wrapper file systems. Data Recovery Mac has an interactive interface and possesses worth recovery and restoration options.
