Check if there are any problems on the hard disk

The Check Disk utility, also known as chkdsk (since this is the command you use to run it), scans your entire hard disk to find and fix problems. It is not a very exciting tool – and its use may take some time, but it can really help to avoid major problems and long-term data loss. Chkdsk performs a number of functions depending on how it is performed:

The basic function of Chkdsk is to check the integrity of the file system and file system metadata on a hard disk and correct any logical file system errors found. Such errors can include corrupted entries in the master file table (MFT) of a volume, incorrect security descriptions associated with files, or even timestamping or file size information misaligned with individual files.

Chkdsk can also, as an option, scan any sector of a hard disk drive to search for defective sectors. Bad sectors come in two forms: the bad soft sectors that can occur when data is poorly written, and the bad hard sectors that can occur due to physical damage to the hard disk. Chkdsk tries to solve these problems by repairing defective sectors and marking defective sectors so that they are not reused.
