“Do you still have the Media Drive LVD connected?” – No, these drives are disconnected.
“You may have a bent pin on the SCSI cable.” – All the pins are straight on the SCSI cables.
“If you changed the Id on the RTR320X, then you need to change it back.” – How do you change the ID? Is it something on the drives or in the computer? Would plugging in another raid change the ID, which in turn would need to be changed back?
“The RTR chassis has status lights on the front and the back. On the back, all the lights above the drives should be green. If they are not, you have a failed drive.” – All lights are green on the back on the drives.
“it is quite easy to plug the SCSI cable that connects the computer to the drive upside down on this drive.” – We haven’t unplugged the SCSI cable form the back on the raid, just from the back of the computer, so I assume we’re all good there.
Is there anything that can happen to the computer to make the drives not show up? Or if all the connections are good, should we be seeing the drives? Thanks a lot for you help on this!
