Use the Dell Diag/Utility disk that came with the system, and do a hard
drive scan from that.  It will tell you if there is bad sectors on the
drive.  If it is still under warranty then dell will replace your drive.
 You should also be able to look at the system logs and see if SMART is
throwing any errors when it is trying to read or write to the drive.
