The drives are sata.
The virus issue is a non issue it is a fresh install of XP with no connections to other pcs, the internet, or files/applications loaded.
The drives do not list any driver loading in the install instructions so I am guessing that is a non issue.
The bios is my guess as to the culprit. because that is where I see the problem manifest most often (no hard dive is listed as the bios displays the drive scan half the time.
