This is the Scan Disk option, as it used to be known on Windows 9x/ME.
Open My Computer and right click on the C drive. It should be called Local Disk ( C: ).
Select Properties, then click the Tools tab. In the top section called "Error Checking", click the "Check now" button.
Error checking doesn't perform when Windows is active so you will get a message askiing if you want to schedule error checking on the next Start Up. Say yes, then either reboot your computer, or follow the prompts if a Restart is offered to you.
The computer will re-boot but before it fully loads Windows will start the error check. It may take some time.
If you have more than one hard disk, do the same procedure for each disk.
I hope this helps.
My computer has been freezing up latley. I tried to do system restore but it will only let me go back one day. I am also getting a message that says firefox.exe- the file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume C:
Can anyone help out?
