My bios and disk mgmt. won't see 2 sata drives hooked into my comp. They are on sata 1 and 3 however it sees 2 and 4. Do I need to do something to set them both to slaves? I'm not really sure how that works with Hard drives? I installed the 2nd hd with no problems, not sure whats goin on with 3 and 4, please help.
