I recently aquired two new 120GB SATA2 HDD from my friend. Previously I used a SYBA Controller card to control my DVD drives since my old HDD is IDE. Anyway I got my SATAs hooked up installed my Controller and plugged my old HDD into it. When I boot the system the controller says it noticed my old Maxtor drive. When I get into Windows it doesn't detect the drive. I know the old HDD works because I hooked it up to my MoBo and finished formatting it. Any ideas? EDIT: I've tried plugging it into my DVD drive and the drive works. I think the problem may be with the jumper on the older hard disk. I'll report back when I get my answer. EDIT2: First I removed the jumper, which made the disk change to CS (Cable Select). It still did not work so I removed the hard disk from the machine. I then noticed that before I removed the jumper it was already set to CS. I set it to Master and the drive works flawlessly. I'll Peace; later.
