Is your Mac OS X hard drive not operating anymore? Is your computer unbootable or unresponsive? Such difficulties may occur due to catalog file related problems in Macintosh operating system. In such instances, your system may not boot and will not let you access the hard drive. Generally missing or damaged system files cause such troubles and lead to severe data loss situations. Restore data from the most recent backup to prevent data loss. However, if you do not have a backup copy of your significant data, Mac Recovery is the way to go.

In a practical scenario, you may encounter one or more of the below mentioned behaviors while starting your Mac OS X system or while working on it:

•    The hard drive(s) are not functional.

•    You get “Reserved fields in the catalog record have incorrect data” error message while starting the system.

•    You encounter “The volume Macintosh HD needs to be repaired” error message while trying to repair hard drive using Disk Utility.

•    When you run Disk Utility, it says that the disk can not be fixed.

•    System shows memory issues and the hard drive volumes can not be mounted.

•    You get empty blue screen at startup.

Irrespective of the symptoms and causes of these problems, it causes data loss. To get your mission critical data in such situations, find out the cause of this issue and solve it through File Recovery Mac.

Root of the problem:

You may come across this after updating third-party disk management and disk repair utilities. It generally occurs, if the newer version of application is incompatible with the version of Mac OS X that you have currently installed.

Mostly this is due to corruption of the file system, catalog file, or other key data structures of Macintosh operating system. After corruption of system files and data structures, Mac OS X can not find the boot files and thus refuses to boot.


You can fix this issue by performing ‘Erase and Install’ in Mac OS X operating system. However, this also removes all the data from your Mac hard drive and causes further data loss.

To recover lost data in such cases, Mac Data Recovery is advised. The recovery process is quite safe, effective, easy, and quick through advanced File Recovery Mac Software.
