I have an older housing for an 80gb hard drive that I no longer use. Yet recently I decided I needed a second disc drive on my PowerMac. So I took an old CD drive out of a 2002 dell and hooked it up to the connections on the inside (IDE I believe?) of the now empty external hard drive casing. The connector looks like this: The CD drive gets power, yet when I plug it into my PowerMac, nothing happens. Is what I'm trying to do even possible? I'd love to know!
