CHKDSK Warning: F Parameter?

Tom from Pennsylvania writes:

I am running windows XP home edition service pack 3. I was running the CHKDSK and a warning come up that the F parameter was not specified. Can you elaborate on this? I have had the computer shut down and reboot while I was using it, is why I was running CHKDSK. I am using Microsoft Security essentials for virus protection.


The chkdsk utility is a built-in program from Microsoft which scans, verifies and can fix some file system errors and hard drive corruption/errors. You can launch the utility from Windows by opening a command promptĀ (hold down Windows Key and Press R key, type cmd.exe and press enter) and typing chkdsk. The error you are receiving about theĀ f parameter indicates you’ve not told chkdsk to fix errors it has found.

The Chkdsk command has quite a few syntax options, the format to use is: chkdsk [volume:][[Path] FileName] [/f] [/v] [/r] [/x] [/i] [/c] [/l[:size]]

You may be prompted that a volume “Cannot be scanned due to it being in use” or “Unable to be locked. Would you like to scan on next restart?” It is a good idea to select Y for yes, then restart the machine to allow chkdsk to run. Most often when scanning your primary C hard drive for errors with the intention of repairing and fixing bad sectors, you would use the following syntax: chkdsk c: /f /r
