3B1 hard disk gone south? (HELP!)

[Kris A. Kugel]

I MOVED my unix-pc, and suddenly the machine won't boot
off of the harddisk -- all 4 leds remain lit, and the screen
fills up with those cute little squares.

I managed to boot off of the floppy disk (Foundation set #2),
when it asks for disk 3 and I insert it,
it fails: (3 identical HDERR lines)

#HDERR ST:1 EF:4 CL:4200 SN:4200 SC:4202 SDH:4220 DMACNT:FFFF DCRREG:F0
MCRREG:8F00
#HDERR ST:1 EF:4 CL:4200 SN:4200 SC:4202 SDH:4220 DMACNT:FFFF DCRREG:F0
MCRREG:8F00
#HDERR ST:1 EF:4 CL:4200 SN:4200 SC:4202 SDH:4220 DMACNT:FFFF DCRREG:F0
MCRREG:8F00
panic:iinit

I once saw an explanation of these message, but I cannot find
it in the notes I have saved.
A copy of the system diagnostics says:
	Recal Disk

	Hard disk restore failed

				** ERROR **
Test   : Hard disk test( Drive 0 )
Subtest: Recalibrate.
Pass   : 3
Error  : WINCHESTER:Can't Recal:Response = 4

and then some more similar message for subsequent tests,
all compaining they can't Recal:Response = 4.

I can't find my references to the meaning of the HD errs,
does anybody out there have any ideas on how to fix this?
