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.
