Chkdsk performs a couple of functions, depending on how itâs run: 1  Chkdskâs basic function is to scan the integrity of the file system and file system metadata on a disk volume and fix any logical file system errors that it finds. 2  Chkdsk can also optionally scan every sector on a disk volume looking for bad sectors. Bad sectors come in two forms: soft bad sectors, that can occur when data is written badly, and hard bad sectors that can occur because of physical damage to the disk.
The rank of colonel is typically above the rank of lieutenant colonel. The rank above colonel is typically called brigadier, brigade general or brigadier general.
