CHKDSK /F, CHKDSK /R, and CHKDSK /X are the most commonly used CHKDSK commands. Based on the disk error types, you can use the different CHKDSK commands and switches to fix hard drive errors. CHKDSK /F VS CHKDSK /R VS CHKDSK /X, What's The DifferenceĬHKDSK can fix two types of disk errors: logical errors and physical errors. Then, it automatically fixes these errors as well. Besides, CHKDSK also can be used for detecting bad sectors on the target disk that occur because of physical damage. What is CHKDSK /F /R /X?
