This is not much difference between chkdsk /f /r
and chkdsk /r /f. The only difference is the sequence of two parameters /f and /r. /f stands for correcting errors on the target disk and /r stands for locating bad sectors and recovering readable information. Mostly, the correct form should be chkdsk /f /r. Basically, when we don’t know if the target drive contains bad sectors, we suggest you run the general CHKDSK command: chkdsk /f/r/x together.
