have changed my CD0 mountlist (which uses CacheCDFS) from scsi.device unit 1 to 1230scsi.device unit 2.
You should also run Prefs/CDFSPrefs resp. Prefs/CacheCDFS and check if it complains about some settings (e.g. direct-SCSI, change interrupt, motor-off etc.) and if it does, save the new settings.
When I insert a disc, it takes ages for the disc to be recognised, but eventually the icons appear on Workbench.
Does that also happen if you don't connect the data cable (only power) ? Then it might hint on some dirt in the drive or a weak / misaligned laser or something like that.
Bye,
Thomas
