chkdsk /r or chkdsk /r /f

[2teky]

I always see people post about running chkdsk /r /f but i thought that chkdsk /r did all the repairs on the disk. Why would you run chkdsk /r /f instead of just chkdsk /r

bump.

/f - fixes errors on the disk
/r - Locates bad sectors and recovers readable information (implies /f)

directly from the chkdsk /?
It would seem all you need is /r

i have always used r but i noticed ms seems to recommend f in vista

Here's some info from Microsoft's site about this...

Looks like /f doesn't check for bad sectors while /r does
