Mac Volume Corruption due to Damaged Disk Image
HTML clipboard
Mac OS X Disk Utility allows creating disk image with 128-bit encryption. A disk image is referred as a file which contains entire disk contents and its structure. Mac Data Recovery experts suggest creating images of volumes or important files and folders as data backup on regular basis. Mac OS X saves these image files with .dmg file extension that can be of any size. When recognized and double-clicked in Disk Utility, the image file is mounted as a virtual volume.
But sometimes, damaged or corrupted disk images can create issues for directory structure of Mac OS X volume. If the disk image is damaged and is being attempted to mount, it can bring serious problems to volume integrity. Mac OS X 10.4.9 and later versions can easily detect disk image damage and give the following alert:
“The disk image you are opening may be damaged and could damage your system. Are you sure you want to open this disk image?”
This alert appears when user tries to open or mount damaged disk image. Earlier versions of Mac OS X could not efficiently recognize such damages. So, opening or mounting damaged disk images can corrupt Mac OS X volumes. It may also happen if user clicks to open damaged disk images after the above alert.
To repair volume corrupted in this way, you can try these steps:
• Open affected volume with Disk Utility and repair
• If Disk Utility can’t repair the damaged volume, run fsck in single-user mode
• If problem persist, reformat the disk and restore lost data from recent backup. Reformatting recreates all disk structures, but with reference to earlier data.
If data backup is not valid, complete or is not present, you can simply use third party Mac Recovery applications. These are special tools that can scan the affected drive and restore all lost files and folders with original content and view.
