Ah, but what size sectors? If 1024 byte sectors (floppies), it could be 
a corruption that occurred on the harddisc (512 byte sectors). I had 
similar myself when things got really badly messed up when !PC trashed 
its image file. Thankfully it was an image and not a real harddisc.

On a (barely) related note, my old boss ran his computer with a failed 
CPU fan. It was a 2xxMHz early Pentium so it worked okay through Autumn. 
I offered to replace the fan for a tenner, but he was a cheap b**tard. 
When it got cold in winter, he turned the heat on. It turned into the 
Sahara in his office, overheated the motherboard, and since the SIMMs 
were just above the CPU, it all went pear shaped really quickly when the 
memory started to malfunction. It would seem, from poking around the 
drive hooked to my RiscPC, as if the swap file was written to random 
locations to the harddisc, trashing everything.

Those SIMMs would no longer work in the PC, but they worked quite 
happily at the more sedate pace of a RiscPC. ;-)


At any rate, good luck and he's hoping things are okay with the originals.


Best wishes,

Rick.
