i've recently switch from windows me to windows xp and i'd noticed that there's no more scandisk. so, are there any other ways to scan my system for any errors?
Or alternatively, open a command prompt:
( Start - Run - CMD )
In there type: chkdsk /F
eg chkdsk c: /F
Usually you will then have to reboot (at your convenience) before the check can take place as the drive cannot otherwise be locked for exclusive access to enable it to be scanned safely.
