How to Run Check Disk at Startup in Vista or Windows 7

================================
Disk issues can get serious very quickly so I would thoroughly check the drive now and be sure
to keep redundant backups of your important data (use several methods).

32 or 64 bit and they are not copy protected) or make one. Also your System maker will sell the
physical disks cheap since you already own Windows.
chkdsk /f /r
