Mac OS X file system issues are generally corrected by running 'Disk Utility'. But at times, when corruption is severe, even this utility fails to perform expected repair and quits while prompting some errors. If you come to such situations, you should primarily look for a valid data backup that might be used to restore lost or missing data. The present scenario depicts one such problems, which if occurs, can raise the requirements of Mac Recovery using appropriate solutions.
To narrow down these problems, we have considered a specific case of a Mac OS X 10.5 (Leopard) user when he/she finds his computer hung up. The computer becomes unresponsive and won't allow you to start or quit any application. Since the computer is completely frozen, you get compelled to perform a hard reboot of the computer.
The next time, when you try to boot the computer, it won't start. Using 'Disk Utility' from Leopard startup disc won't help either, as the utility seems not to repair the disk, and prompts the below or similar error message on screen:
"Incorrect block count for file file_name"
Note: At times, the above error can be benign, when the file system journaling is turned on and you run fsck utility. If this is the case, you can safely ignore this error message.
In case, data gets inaccessible because of the above stated issue, you should consider applying suitable solutions, mentioned in the 'User Action' section.
- You can try repairing the corrupted file system by running fsck after booting the computer using the Mac OS X startup disc
- Mirror your hard drive by attaching it with another computer or check the availability of a valid data backup and then perform 'Erase and Install' of Mac OS X
- Use a third-party Mac data Recovery Software to recover and restore lost and inaccessible files and folders. A Mac Recovery utility is designed to scan logically crashed Mac OS X disk and retrieve lost information.
For comprehensive data recovery results, you can use Stellar Phoenix Macintosh Data Recovery software. This Mac file Recovery Software is one of the well-known tools that is compatible with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.
