SCSI madness
« on: April 24, 2011, 01:07:08 AM »
I swear to God, if I ever meet the guy who invented this damn standard I'm going to throttle him. Here's the deal: I have an Amiga 3000 that came with:

* A 50MB Quantum Prodrive LPS as SCSI ID 1
* A 4.5GB Seagate Barracuda ST34572N as SCSI ID 4

I have an 850MB Quantum Trailblazer I'd like to replace the ProDrive with (currently set as SCSI ID 2,) but I want to copy the files from the ProDrive to the Trailblazer so's I don't lose the WB3.5 install the computer came with. Problem is, SCSI is Deep Magic and it seems like every time I get one thing working another stops.

Currently, it doesn't seem to recognize any of the drives alone or in combination, despite the fact that it all of them are in perfectly funcitonal condition. I've tried enabling and disabling termination on the Trailblazer (the others don't have a jumper for it,) I've tried fiddling around with SCSI IDs, I've tried swapping positions on the cable - nothing.

The hard drive LED on the computer does a very soft blink like it's being turned on very briefly and then off for longer periods, but it doesn't show any actual hard drive activity. (In some configurations it comes on solid and just stays that way.) The boot menu and HDToolbox don't show any of the drives as being connected besides DF0. The Barracuda goes through its normal spin-up and initial chatter, as does the Trailblazer, but the ProDrive does it spin-up and then a brief bit of quieter chatter than usual.

I am completely lost here. I don't understand anything about why SCSI does or doesn't work in whichever configurations - all I want is just to get the ProDrive and the Trailblazer to work together first, and then the Trailblazer and the Barracuda after. Can anybody help me figure this out?

Not really an option at the moment - I've already dropped a bit more on this than I should right now, and besides, I've got these perfectly good drives that I'd hate to see go to waste.

Aaaand after a full afternoon of dicking around with this, I discovered that the cable had popped out of the socket on the motherboard end D:

Only on SCSI could the symptoms be so inconclusive that I didn't even notice...

Well, I've actually got it working now - it was pretty much just the issue of the cable having popped. Bleargh...
