3650 HD repair

[Scott_Busse%mindlink.bc.ca@Warbucks.AI.SRI.COM (Scott Busse)]

Back in the land of Symbolics!

I was blessed with a visit from Mike Western of Symbolics (Seattle)
yesterday, and he coaxed my 3650 back into running order (under
Genera 7.2), from the previous hard drive crash a while back.
   The problem seemed to be a substantial mess of errors that all
occurred on the same surface (surface 7). The main problem was that
many of those errors were in the world file, which prevented it from
booting up Lisp. There was liberal application of (si:fix-fep-file),
which ultimately got most everything back (I still haven't gone at
the LMFS files yet, but will tonight), but a few errors came up that
were not totally resolved...
   While doing the (si:fix-fep-file), after the file was completely
read through, the prompt for what to do was presented, and at this
point when the (S)plice option was chosen, an error came up
that invoked the debugger...(the case of the error msg txt is
probably wrong here and maybe the odd space is missing...)

Unexpected Error: %DISK-ERROR-UNKNOWN-STATUS during a %DCW-READ32
  on unit 0., cyl 1281., surf7., sec7.,
Disk error,
  1. pending transfer SI:CHECK-FEPFS-TRACK
  Arg0 (SI:START-DPN): 461328

Returning from the debugger allowed the system to continue and the
eventual deleting of the files where this occurred seems to have
been successful in returning the space to the system. Mike repeated
the procedure on all newly created files, and generally it appears
that everything landed ok.

Another error came up when the (D)elete option of (si:fix-fep-file)
was chosen (after the file was completely parsed)...

Error: Can't find DPM 1605 data map #<art-Q-90 17051725>
 SI:FEP-REMOVE-BLOCK-FROM-MAP.
 Arg0 (SI:DPN): 461711
 Arg1 (SI:DATA-MAP): #<art-Q-90 17051725>

Again, exiting the debugger (with no action taken, I think) allowed
continuation...

So I'm wondering if anyone has encountered these errors, and has any
ideas for me to pursue. Note that for the few hours that I used the
machine last night, everything worked ok. I am going to attemp to
(si:fix-fep-file) and delete the existing LMFS files, and replace
them with new ones some time today/tonight. Any precautions or
insights are always appreciated.

If I get terminated, I'll be back :)
