chkdsk/f or r

[KARATEJOHN]

What is the difference? Is one better than the other? Which one should I use, use both, or use chkdst/f/r which I currently use. How often and does it harm the HDD?

/f = fixes all fixable issues (run without this switch if all you want is a report)

/r = checks for bad blocks (/f automatically applied)

Checking for bad blocks takes considerable time and is not usually necessary. However, if /r does turn up any bad blocks you should immediately backup and start looking for a new drive.
