There are a few people I know that have been having problems with Adaptec AHA-2940AU/UW controller's unless power is supplied to the terminator. Using bus power created problems for those systems. I have also had a bad power connector on an internal power supply. It is usually the one on the end of the daisy chain. If you have a free power connector you might replace the connector you are using to power the CDROM with a free one. If you don't, add a Y cable and then use the new connector for power. I have also hooked a scsi cable incorrectly. Nothing on the scsi controller worked when I did that. You can't hook a scsi cable up to a CDROM off one pin like you can some devices. Nothing worked when you do that either. It seems like you end up with a ground on a data line or power.
