Hello. I own an Acer Aspire that was purchased in 2002. It used to have a 20GB IBM hard drive. I decided to replace it today with an 80GB Seagate HD. When I went to load XP on it, I was told that Setup could not detect a hard drive. Checking the BIOS, I saw that there was no HD listed, either. Looking around, I've seen some recommendations about editing the SATA settings in the BIOS, but SATA does not show up at all among my options. I'd really appreciate any advice on how I can solve this problem. Thank you so much!
