Usually the format command is something vendor unique when using a
bridge board (whether it's controlling ST506/ST412 drives, tape, floppy
disks or whatever), but IME everything else works logically for just
shunting data around.

There may of course be vendor-unique test routines or query routines
built into these boards, but for typical running they just behave like a
mass-storage device with multiple LUNs.
