Mac users are often surrounded by various uncertainties when their system starts behaving unusually, shows cryptic error messages, or crashes unexpectedly. This behavior is usually encountered owing to corruption in the underlying file system. If any volume has faced a serious corruption, you will not be able to access files stored on that volume or even see some invalid data in those files. This is pretty common in case your system is infected with a virus or has experienced a hardware malfunction. In order to avoid a major data loss catastrophe on your system, it is necessary to do a preventive disk maintenance regularly. This can be accomplished using the inbuilt Mac OS X utilities. However, if you are unable to repair corruption, you should go for reliable Mac data recovery software as the last resort.
Mac OS X provides a 'First Aid' toolbox to its users. You can run 'First Aid' periodically to verify your startup disk for errors and repair corruption. It is a wise option to check your disk in the first place and prevent small problems from growing into big ones.
To go for a startup disk repair, you need to have the software installation DVD. Use the following procedure as described below:
You should run 'First Aid' repeatedly until you see the following message on your screen:
The volume "diskname" appears to be OK.
Some of your volumes cannot be repaired using the 'Disk Utility'. In such cases, you may see the following output message:
Scan complete. Problems were found, but Disk First Aid cannot repair them.
In such circumstances, you should take help of professional Mac data recovery software. These third-party tools efficiently repair your severely damaged volumes to recover every piece of valuable information. They support FAT, HFS and HFS+ file systems. Moreover, they are compatible with the latest Mac OS X 10.7 Lion and other lower versions.
