That is so NOT-GOOD on the scsi bus. Under scsi-1, it was considered a
horrible deed to plug a scsi device into a working, powered-on scsi bus.
Why this is, I never asked, and I don't know if it's changed since the
invention of scsi-2, but hot-plugging a bus that is not made for it is
supposed to dammage it.
