Does CHKDSK fix corrupt files

Use CHKDSK regularly to scan your hard drive for corrupted files, help repair and clean up your PC, and maintain its health. CHKDSK can scan for bad sectors — ruined parts of your hard drive — even when your PC won't turn on. That helps you find and fix hard drive errors, and frees up disk space as well.

Generally chkdsk /r not only does the same thing as chkdsk /f, but also checks the bad sectors on the hard disk and tries to recover the readable information. Running chkdsk /r also means that the chkdsk /f is run. However, running chkdsk /f will only check for logical disk errors, but not bad sectors.Repair a storage device in Disk Utility on Mac
