The message warning f parameter not specified while running the CHKDSK command in windows 7 may appear due to the program running in scan-only mode. It happens when windows find a problem with the system if the check desk command is run without specifying the F(fix) parameter. 

However, if your computer displays such a message, your hard disk might have some errors and they can be fixed by running the command ‘chkdsk’ with the f parameter being specified.

What Does Warning F Parameter Not Specified Error Mean

‘CHKDSK’, aka check desk, is a command in Windows that scans whether there are any errors in the hard disk and the F parameter is the command that fixes those errors identified by the ‘CHKDSK’ command. The F parameter is programmed to fix any logical error ‘chkdsk’ finds. 

However, when ‘CHKDSK’ is run alone without the F parameter, windows only check the disk, it doesn’t fix any errors.

So whenever you see a message saying the warning f parameter is not specified on your computer, it means the program CHKDSKhas been run and it found errors but since the f parameter was not specified, it couldn’t fix them, therefore the notification came up.

How to Fix the Warning F Parameter Not Specified Error Effectively

To fix the issue, the only thing you need to do is to specify the f parameter while running the chkdsk command. Because when the f parameter is specified, it tells the windows to fix all those errors identified by chkdsk.

Here are the steps to follow –

Step 1: Press the Windows key + R and type cmd.

Step 2: Press and hold the Ctrl + Shift key and click OK to open the command prompt as administrator.

Step 3: Type the command “chkdsk /f” and press Enter.

Note: The command may take quite a long time. But it would be safer not to stop the process until it completes.

What If Chkdsk /f Doesn’t Work

The command chkdsk /f may not work due to the following reasons –

• Third-party interference, 
• Disk failures, 
• Raw partition, 
• Fast startup enabled with a multi-windows OS system, 
• Write protection on the drive.

However, you can Disable the fast startup, run the Fsutil Command, or Disable the write protection switch to solve the issue when chkdsk is not working.

Frequently Asked Questions

What Is Warning F Parameter Not Specified?

The F parameter not specified means a program named check disk got run on your computer to find out if your hard drive has any problems and found some issues but couldn’t fix them due to the f parameter being missing. If the f parameter was specified, then it could easily detect the root of the error and could solve that.

What Is the F Parameter in Chkdsk?

F parameter in chkdsk is used to fix the error in the hard disk of a computer. But the condition is the disk must be locked. 

To Conclude

Your windows may display a warning that the f parameter is not specified. In that case, it indicates chkdsk has possibly located some errors on your hard disk and running chkdsk /f is most likely to solve the issue. However, if you are still notified of problems, it would be more helpful to contact your local computer technician.
