For my (belated) birthday, a friend of mine gave me a CDRW drive. His dad is a computer guy, they have like 4 computers, networked, all of them upgraded out the wazoo, he's real good with computers. So we put in the new CDRW drive, under the old CD-ROM. The old one is the master, the new drive as the slave. When we booted the computer, in BIOS mode, both drives were recognized. When wondows loaded up, neither drives were recognized. Right now, I don't have any CD-ROM drive at all. Neither of the two work. We made sure the cables were all connected the right way, the red stripe is closest to the power cable, etc., yet windows still does not recognize either of the drives. Both drives open and close when I pust the button; they both have power. Any help?
