General SCSI CD-ROM Troubleshooting
If you have installed your SCSI host adapter and drive properly and have installed the requisite drivers (described in the following sections) and your drive does not work, check the following items before proceeding to other troubleshooting steps:
Is the host adapter installed in a bus-mastering PCI slot? Verify with the system or motherboard documentation that the chosen slot supports bus mastering, or try another slot.
Are all SCSI devices turned on, and were they turned on when you booted the system? The SCSI adapter recognizes only devices that are active when the system boots. If necessary, power down all SCSI devices, turn off the computer, turn the SCSI devices back on, and then turn the PC back on.
Are all SCSI cables and power cables connected properly? Verify that the Pin-1 orientation of all SCSI cables and devices is correct, and that the power cable is fully seated in each SCSI drive.
Does each SCSI device on the bus, including the host adapter, have a unique SCSI ID, and is the bus terminated correctly? If not, correct the ID assignments and/or termination and restart the system.
If SCAM is enabled on your host adapter, are you certain that all connected devices are SCAM-compliant (or at least SCAM-tolerant)? If not, either replace the non-SCAM device, or disable SCAM on the adapter and configure SCSI IDs and termination manually.
Are you certain that you have installed all driver software that your adapter and/or devices require?
