Thanks for your reply. I have swapped them.

I wonder if it even cares about the disks. There is supposedly a reset mode (six blinks?) that will boot up without mounting the disks. I tried that with the same result.

Yesterday it booted up from each one of the original drives in tandem with the upgrade drive. Only once, though. Each time rebooting led to diagnostic blinks.

I just feel like I strayed into a realm of clairvoyant experts. These debug commands, for instance-- if it weren't for these forums I wouldn't know they exist. Where is this stuff documented? I see the list of commands, but how do you guys know what they mean?

Anyhow, I would rather this device be useful to somebody who knows what they're doing than to rust on my shelf.

It used to be valuable to me. To someone with the nous it could be valuable again.

No reasonable offers refused.

Thanks,
