Thank you, yes that question was answered I only have the one hard drive in my computer and it is a SATA! The original one in my computer was a sata, the first new one I bought was an IDS but I replaced it with a sata when I realized thats what I needed. I have everything disabled in BIOS except for the cd drive, thats how I done it every other time I re-installed windows. My new harddrive did not come with directions or a disk or anything. It is a HITACHI Deskstar 250GB.
