Did you forget to sacrifice a chicken to the SCSI gods? Your settings are the same as I have on the 24x Apple CD-ROMs in my PCI Macs (parity, ID#3). I've gone through the original 8x on the 7500 and the original 24x on the 9600. When the 8x died it was doing similiar things, even though it was still recognized by ASP. One thing that might work is to hard reset the logic board by unplugging the computer and removing the PRAM battery overnight. This has cleared up SCSI and PCI problems with my 9600 when nothing else would. But my guess is that the drive is dead. -+-+-+- RPM -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
