If your drive spins up and then stops shortly, it is likely that it
either does not come fully up to speed or it is unable to unlock (or
unstick) the heads from the park position. (I'd bet on the heads.)
Can you hear the usual clickety noises that a drive makes when it
initializes?

I double checked all the board numbers, and
everything but the ST-506
interface does indeed match the build/maintenance sticker. The tag from
that board states "Removed from IRIS Suspect U/S - no diagram". The
'U/S' might actually be 'U/5', but it is somewhat hard to read. The
board is a standard Multibus board. It was made by Data Systems Design
(Qualogy) and has a part number of 805215-08. Does anyone have a
databook or even prints for this board? I'm going to assume for now that
there is indeed something wrong with it, since it appears someone
"borrowed" the original ST-506 interface from this 1400 for another
system. This particular board might have come from a later IRIS system,
but it appears the 2000s and later used a 5217 instead of a 5215.
Maybe replying to my own emails is a little "different", but oh well :)
Tonight, armed with the user's manual for the DCD 5215, I managed to run
various diagnostics in order to help troubleshoot the board. Test 1F (8085
Environment Self-Test) seemed to pass, and test 1A (CR1, CR2 Blinking
Wakeup Address) seemed to pass as well. When I ran test 1B (R/WC
Self-Test), I got an error 45 (Read/Write Controller Error). Further
investigation seemed to indicate the hard drive itself wasn't spinning, so
I removed the top panels and powered up the drive. It seems to spin up ok
for about a minute, then shuts down completely. At this point, it
certainly looks like I'm looking at a malfunctioning drive instead of the
DCD 5215. Due to the fan noise, I never even heard the drive spin down
until I pulled the top panels back off, sigh...
This system uses a Vertex V170 (60MB?) ST-506 drive. Is anyone familiar
with them? I'm guessing I may just end up having to replace the drive with
something else. Does anyone have any brands/models they'd suggest trying
in this system?
