‘Data Loss’ – the term frightens all most all computer users. In day to day computer usage, there are many unintentional incidents, resulting in the loss or inaccessibility of valuable data. Among them, accidental file deletion is quite common and every Mac user must have encountered one or more such incidents. However, now there are many Mac file recovery utilities available in the market, which can help you recover all your deleted data back.
Many times, while trying to delete unwanted files, you delete many folders from your Mac system, without even verifying the files in them. At times, such steps result in the loss of important files that were there in those deleted folders. Users also lose their precious data to accidental deletion of files or formatting of storage media. Apart from these, there are incidents of sabotage or deletion of important files with ill intention.
However, one fact is about these deleted data is that even after deletion, they still remain in the storage media. When a file gets deleted, Mac operating system removes all the entries of that file from the memory so that the file cannot be found anymore. Moreover, the OS marks the memory allocated to that deleted file as free, which indicates that if you will try to save a new file onto the disk, then the freed memory can be allocated to that new file.
But, if you can keep the deleted file from being overwritten, then that file can be recovered using any Mac data recovery software. These software are developed with highly advanced search algorithms, which thoroughly scan the storage media and finds out the lost entries of the deleted files. By reading those lost entries, the software recovers the deleted files/folders back.
Stellar Phoenix Mac data recovery software are developed with complete compatibility with almost all current Mac OS X Lion 10.7.2 This software is absolutely read only and while recovering, never make any change neither to the files nor to their structure.

Recover Lost Data from Corrupt or Damaged HFS Volumes
HFS or the Hierarchical File System is the mostly used file system in Mac. Before going for HFS plus, Apple has offered HFS file system with various hard drives as well as external storage drives for Mac systems.
Though, HFS is considered as a stable file system for Mac OS based systems, still there are instances, when the HFS file system becomes corrupt, leading to the loss or inaccessibility of precious data in the drive. However, with the help of advanced Mac data recovery software, you can recover all your data from the damaged Mac partition/volume.
Symptoms indicating file system corruption:
Below are some of the prominent symptoms that indicate possible corruption to the file system -
• Files either will not open or open with garbage data
• Files/folders missing from their original location
• Folders, surprisingly empty
• System fails to boot or takes unexceptionally long boot time
• You experience problem in coping or pasting files
In day to day computer usage, there are various common instances such as sudden system shut down, virus/malware infection, system crash, software/hardware contradiction etc., which are responsible for file system corruption.
The file system stores information about the volumes as well as the data areas in them. When the file system gets corrupt/damaged, the OS fails to gathers these information and the data in the volumes becomes inaccessible.
In order to resolve the problem, you need to run the 'fsck' utility. Below steps will guide you through the process:
• Run the 'Unmount' command at the HFS file system. This will unmount the HFS partition.
Note: If you are running the system in single-user mode, you need not have to unmount the file system.
• Run the command, 'fsck -p'. This option finds out file system corruptions in the volume and fixes them as well.
Sometimes, due to severe corruption of the file system 'fsck' even fails to resolve the issue and in order to get rid of the problem, you need to format the volume and. But, with formatting, all your valuable data in the volume will be lost. However, you can use any Mac data recovery software to recover the formatted data back.
These utilities are designed with highly advanced algorithms to recover any of your lost, deleted or formatted data from your Mac OS based volumes. Moreover, these data recovery utilities are easy-to-use, without any further assistance

Recover Mac data in case of error - You have inserted a disk containing no volumes that Mac OS X can read
Target Disk Mode or in short TDM is a unique boot mode in Macintosh computers. This boot mode helps you connect your Mac system as a firmware mass storage device and access the data from it. The Mac system booted in Target Mode can be connected through a FireWire port to any Mac or Windows system.
This is extremely useful, in case your Mac system containing all your precious data has failed to boot. However, if you try to boot your Intel based Mac system in Target mode, it fails. Moreover, at times, the Mac volume or drive becomes surprisingly corrupt and becomes completely inaccessible. In such situations, you require any good Mac data recovery software to recover the data back.
You can boot your Mac machine in Target mode by continuously pressing the 'T' key from the keyboard, while starting-up the system. The hard drives connected in TDM can be partitioned or formatted as usual. Users even connect their CD/DVD drives and other such peripherals to the host computers using Target Mode and the resources are easily shared. The problem arises only in case of Intel based Mac systems. Intel based Mac systems, while opened in Target Mode, the operation fails and flashes error message as below:
“You have inserted a disk containing no volumes that Mac OS X can read”
Though, in some versions of Intel Mac, TDM works, still in most of them it fails with the above error message. In such situation, the error dialog box opens with three options – 'Initialize', 'Ignore' and 'Eject'. Here, you must only opt the options, 'Ignore' or 'Eject'.
There are situations, when users do not exactly understand the functionality of an option and perform the operation with curiosity. If by mistake you choose the option, 'Initialize' then the drive will get initialized, leading to the loss of all your data in it.
However, be it the case of your formatted Mac hard drive or any corruption to the drive while booting that in TDM, you can retrieve all your data with the help of any Mac file recovery software. These Mac data recovery software are developed with many innovative techniques to retrieve all your deleted, formatted or inaccessible data back from the Mac hard drive or volume. Moreover, these recovery utilities are completely read-only in nature and with highly interactive graphical user interfaces, quite easy to use.
