Greetings- I just purchased an i/oware (Hi-Val) external USB CD-RW 6x4x6 drive. Just for kicks I thought I'd try to put in a different drive (HP DVD-100i) in the case to see if it would work. The USB stuff comes up fine, but the actual drive hardware is not detected. I'm hoping that the external USB interface is not specifically looking for the original drive, and it is just a matter of a driver for whatever is hooked up to the IDE/ATAPI header. I'd also like to use the USB interface for hard drives. Anybody have any tips on making this work?
