I recently pulled one of my old CD-RWs for A Creative DVD/CD-RW Combo. Pluged in the IDE and power. It powers on; can open/close. Made sure it was enabled in bios. It was. Then I start the CPU and it says there is no drive there? Is there a step I'm missing? It doesnt show up in device manager or anything. I'm pretty sure my IDE cables are still good since it was working before I put in the drive. Dell Dimension 2400 w/ original mobo.
