Is your Mac OS X based system unable to boot normally? Are you encountering a blank gray screen while booting your Mac OS X? Or do you view a broken folder icon/flashing question mark while booting your Mac OS X system? If your Mac OS X based system exhibits any of the above problems, then in most cases the file system (HFS, HFS+, HFSX, and HFS Wrapper) is corrupt or damaged. The unbootability of your Mac OS X system does not allow you to access the data saved in the hard drive. To recover data after file system damage, you need to opt for a comprehensive data backup.

However, in case of no backup availability, you have the option to repair file system using two repair utilities – Disk Utility and FSCK. But if these utilities fail to repair the file system and the system remains unbootable, then you need to use a third-party Mac Data Recovery utility.

To explain the above case, consider a realistic scenario wherein you encounter the below error message during booting of Mac OS X:

“file system dirty, run fsck.”

After the above error message appears, your Mac OS X machine becomes unbootable and the hard drive data becomes inaccessible.

Cause:

The above error message appears when the file system of your Mac OS X gets corrupted or damaged. File system corruption is attributed to unexpected system shutdown, power failure, and forced restart.

Resolution:

To resolve the above error message and to access hard drive files post file system damage:

• Boot your Mac OS X system in safe mode.

• Try an inbuilt repair utility ‘Disk Utility’ to repair your file system.

• Try to repair the disk using a command-line utility ‘FSCK’.

• If above options fail to overcome the above error message, restore data from an updated backup.

• However, in case of absence of an updated backup, you need to opt for an effective third-party Mac File Recovery software. Such Mac File Recovery tools ensure complete recovery of all hard drive data using advanced scanning algorithms.
