Not sure what else...Have you gone to http://www.accelerateyourmac.com
for troubleshooting info? It's a great site.

Also, there are a couple of much more active lists than this one, have
you tried any others?

The part that goes from the motherboard to the CD-ROM drive is wider than the part that goes from the CD-ROM to the disk drive (and looks like a 40 pin cable). This means that I can't use the cable that comes with the new drive.
