Hello.
I'm not so curious than the left mark tells. :-)
Looks like your HD is not conected, or becomes faulty. Open the SX-1 (5 screws) an look at it. Could be the SX-1 conector, either. Put something to lift the CD32 part (and rest the SX-1, of course ;-) )
Some Early Boot Screen information:
DF0: is the floppy drive
CC0: is the PCMCIA (CreditCard device, if any)
DH0: or TDH0: IS THE HARDDRIVE!
There is NO xx8: device in ANY Amiga!
But, if you don't have a set of WorkBench 3.1 disks (6 DD floppies), go for it! I live in Brazil. Maybe far away to send you a copy set.
