At least the Aurora is not my main machine, it just gets used to test
software on a QDOS ROM from time to time really.

So in that sense, even if the drive was lost completely, it's not the
end of the world, as the boot and extensions can reside on the romdisq
and programs can be run from floppy or (slowly) via Sernet for the
testing purposes. Anyway, small capacity 2.5 inch HDs don't cost much
as second user hardware (I do have one lying around somewhere I could 
press into service).

This rather "brute force" approach to fixing things reminds me of what
we used to do in a past job to fix broken CD players. For a while
(until it went bust) I worked for a firm which recycled "brown goods"
and we often resorted to some unofficial maintenance methods to
resuscitate seemingly dead bits. We'd bring dead motors in the 
portable CD players back to life by putting a 9volt battery across the 
3-4.5 volt motors for a few seconds. It was a bit of a juggling act - 
apply the 9 volts long enough to get it going without burning out the 
motor coils.

I live in hope that shouting loud enough at a hard disk will
initimidate it into waking up ;-)
