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 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 Disk 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.
