Well, I'd rather not lose my data so would it be possible to transfer my C:\ and D:\ files over to the two new harddives and keep everything operational? I know it's possible between EIDE drives, but not sure on EIDE -> SATA. I'm running with a AMD XP 3000 64BIT, Asus K8V, and PC3200 1.5GB RAM so I know hardware wise, I'm sufficient for the transfer tasks if possible. Let me know if it's possible and also ideas on how to transfer the drives (Software and what have you). Thanks a lot in advance.
