Sounds like termination or ID conflict issues to me. Cables can be a problem too.
SCSI is the most painful thing to get right - took me about 24 hours of slaving to make my CF card reader work in the E4 a few years back now - for some reason having an internal drive without termination and termination on the card reader would make it fail like you described - no matter what I did. I consider myself a SCSI "expert" form way back yet its still never easy. It would work well on its own - as the only device. I had to also make sure the right jumpers were set on the card reader - can't recall exactly but there were options for async/sync I recall i needed to adjust to async.
Considerations:
Termination - make the simplest setup you can. Terminate both ends. Make sure your not terminating in the physical middle. Lots of data out there.
ID"s - ensure no conflict
Make sure the sampler is ignoring any other host IDs
If using EOS 4.7beta do NOT have your PC/MAC drive on the scsi chain and the sampler and its peripherals...two masters = corruption and loss, in a bad way.
try cables if all else fails. SCSI cables have a ton of connections. It takes 1 earth line to break the whole thing in an infuriatingly intermittent manner.
shorter cables are better but old cables are likely to be suspect.
