Soon after I first installed OS X on my beige G3, the Quantum ProDrive LPS stopped working (stopped showing up in the system). Just randomly started. It is 80 megabytes and empty so I didn't really care and I didn't have time to fiddle with it. This was before I transported it here. It's been not working ever since. Why doesn't it work? Note: The beige G3 is bricked (bad PSU and can't get anywhere) and I have no other computer with SCSI so I cannot test SCSI drives anymore. Second question: What are these three things that plug in right behind the SCSI port? See the image attached. P.S. These old hard drives have such fat logic boards that almost 1/3rd of the device is just the board! When you take the board out, you can see that the actual disk drive is quite thin!
