Preserving/snapshotting the contents of a SCSI

hooking it to a UNIX box and running a "dd" command.
For drives that have 512-bytes-per-block (which is most of them),
that's true, but there is the kink that really early SCSI devices,
specifically many non-embedded drive controllers with attached drives
(commonly MFM or ESDI) don't support the SCSI INQUIRE packet, so can't
be easily connected to modern Linux/UNIX boxes. Probably nearly
everything made since about 1990, though, "plug it in and use dd"
works great.
And, yeah, it was a PITA to connect them up back then too. That's why
INQUIRE exists.
