Fixing bad sectors on WHS hard drive
When your WHS starts giving you hard drive errors make a note of where they are happening, somewhere on C:\fs\{drive letter}. Then open a command prompt and run: chkdsk /r C:\fs\{drive letter} After a few minutes it will then ask you if you would like to force a dismount. Say No. Then it will ask you if you would like to schedule a chkdsk /r the next time the system restarts. Say Yes. Restart WHS.
