Recovering Mac data when volume goes missing

A hard drive in a Mac Operating System based Machine is divided into various partitions to make the OS perform better, These different partitions/volumes can be used for storing different kinds of data in the drive. However, sometimes when you try to access one of the drives, you fail to access it. The error message states that the volume/drive is missing, but it happens because of the fact that the disk drive has been damaged and inaccessible. This condition leads to a serious instance of data inaccessibility or loss .

One error message that depicts such a scenario as mentioned above is -

“No such volume; volume not found”

After facing such an error, you may find yourself in a helpless state. All the data in the hard drive becomes inaccessible and you need to take the help of a Mac undelete software to resume your work back to normalcy.

The above mentioned error occurs due to a possible damage in the hard drive structure. In Mac, Disk Utility is an inbuilt repairing tool that detects and repairs hard drive errors. Here, when you run Disk Utility, you get another error mesage as below:

“Error starting disk utility back ground process”

Another error message that follows the previous one may be:

“Disk Utility started, but a background process needed in disk utility didn't start properly. Please quit and restart disk utility.”

These error messages are the outcome of a serious damage to the hard drive volume or its file system. This may happen due to several reasons like, abrupt system shutdown, operating system malfunction, virus/malware attack etc. Whatever be the reason, the only solution to this issue is to format the hard drive and install a fresh copy of the Mac OS X. This of course leads to complete erasing of data from the drive and a Mac undelete files software can help you recover all your formatted data back.

These specially designed software help you to undelete mac files from any HFS plus, HFS, HFS wrapper and FAT file system based volumes.  With these useful utilities, you can recover your data from any Mac OS X based media, including external/internal hard drive, USB drive, memory cards etc.
