Troubleshooting

Most problems occur due to improper termination or 2 devices using the same ID. Also, check for loose cables or damaged cables.

If your SCSI controller is still not detecting the drive, then you may have selected not to scan for the required ID in your SCSI BIOS. Go into your SCSI BIOS and make sure your ID's are turned on for scanning.

Other problems may occur when you are using SCA drives and an improper adapter. Usually the drives will not spin up, or they will spin up, but the SCSI controller will not detect them. Contact the vendor you got the adapter from and they can provide you with a different adapter.

Cooling is an important factor as well, most 7,200 to 10,000 RPM SCSI drives need to be cooled. If they go above their specified temperature they will heat up and fail. Purchase a HD cooler and install them. It's better to be safe then sorry.

This is the very basics of SCSI. There is far more to cover, but this should just be enough for a common SCSI setup. If your looking for a much more detailed description of SCSI, then I suggest you read this FAQ:

I did not write the above FAQ, and it is a little old. Although, it is one of the best FAQs I found.

That's all there is! :-)
