[Ham-Computers] Re: DIMM vs UDIMM - Essentially The Same?

You said:
 "The process of trying to recover the HDD - not knowing
that the RAM and I/O were variables - resulted in loss of
the partition information, rendering the HDD inaccessible"

The master boot record (MBR) CAN be repaired ~ some times....
If you can start the machine using a DOS startup disk, you can use the 
command: FDISK/MBR. This command will repair the MBR.

I know that you are not running Windows, but the above might work.
