Hello, Me again.
   Ummm... My external drive has taken to emitting a very high pitched
squeal periodically.  I just bought a batch of black disks that seem
to be defunct three times out of ten, so it might be just the disks
making the noise.  Has anyone else had this problem.  Has anyone got 
some advise.  Should I have it serviced?  Should I scrap the disks?
Should I sacrifice a goat under a new moon?  
   I don't know about these disks.  They're black, they come in white
unmarked celophane wrapped boxes of ten without labels.  The guy I bought
them from was a bit of a sleaze, but he says (so it isn't necessarily
true) that they're elephant disks.  They're crap.  As I said, three out
of ten either won't format at all, or die out quickly.
   Back to the tonal external drive.  None of my disks sing in the internal
drive, but not all of them sing in the internal drive.  I suspect that some
variable element in the drives is slightly bunged in the external one,
causing it to be more sensitive to the crap disks.  Any ideas would be 
greatly appreciated.
