Disk Utility Failure Due to Severe Disk Damage
Every operating system faces some kind of problems that make it unusable, no matter how stable and powerful the operating system is. Even the most reliable operating system Mac OS X can face problems that can lead to data loss. In order to handle such situations, to prevent data loss, and needs of Mac data recovery software; Mac includes Disk Utility application.
Though Disk Utility is a powerful utility that is capable of handling a number of issues with Mac OS X hard drive, however, there is no guarantee that it will work in all cases of system failure. There are some situations where Disk Utility may fail with the following error-
