the total wrong place to be asking this. However it's friday so what the hell. Many possibilities:<BR><BR>1) Hard drive could be dead.<BR>2) Hard drive might be disconnected.<BR>3) Hard Drive could have been formatted. <BR>4) System board could be faulty causing the drive to be unrecognized.<BR>5) You could have an unformatted floppy in the A drive.<BR><BR>I'd start with a boot disk and see if you can read the drive at all. That and see if during the POST it is recognized by the BIOS.
