Scanning for File System Data Corruption

Due to the complexity of the file system used on modern PCs, there is always the risk that file system errors and corruption will develop in the logical structures that control the disk. Most of the time, these problems are caused by buggy software, bad drivers, power failures or human error. Rarely, they are the result of actual hardware problems with the PC.

File system integrity problems can on occasion lead to data loss. It is important that any problems be caught as soon as possible, to minimize the chances of extensive damage. Fortunately, checking for file system problems will be set up to run automatically by program schedulers, and we recommend that file systems be scanned for errors on a daily basis. You can do it less often, but you increase the chances of problems multiplying.

Typical problems such as a small number of lost clusters on a disk volume, are nothing to be concerned about. These are usually file fragments left over when a program crashes, or when there is a power failure. Other problems, such as file allocation errors or cross-linked files, happen more rarely. If these are happening a great deal, it may be a sign of a problem such as a hardware failure, too-fast timing on a hard disk, or even virus infestation.
