I have an older computer that I want to use for a spare. I installed a 320 gig hard drive and Windows XP in it. It runs great except that it only sees the first 137 gigabites of the hard drive. I have since learned that this is a well known problem (except to me). Does anyone know a way around this that doesn't involve expensive hardware replacement? I can live with it if I must but I would much rather have the whole hard drive available. Any information will be very welcome. Thanks.
