CHKDSK (short for "check disk") is a command on computers running DOS, OS/2 and Microsoft Windows operating systems that displays the file system integrity status of hard disks and floppy disk and can fix logical file system errors.
In short, It verifies a storage volume (hard disk, partition, floppy disk, flash drive, etc) for file system integrity.
It is equivalent to the Unix command fsck
Use the following options specific to your needs:
/F : Fixes errors on the volume (without /F, chkdsk only detects errors)
/P : Forces a full verification
/R : Searches for defective sectors and recovers legible information (applies /F)
/X : Unmounts the volume before processing if needed. (Note: Unmounting temporarily invalidates all pointers/handlers to the volume until process is completed)
