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.

All the Elephant brand black diskette that I've seen have been 1s2d, and thus might not be wise to use in the amiga. If they haven't polished the back side, that might be what is making the drive sing. Somebody sold one of our IBM-portable users some black diskettes that came in a yellow box marked, "Elephant 1s2d". Needless to say, they did not work out very well, even in the IBM. Sorry to respond via the net. Something is wrong with our news mailpaths file.

The guy I bought >them from was a bit of a sleaze, [...] I've experienced exactly this sort of high-pitched singing sound, not unlike the sound you can get running a moistened finger around the rim of a glass. It has ONLY happened with disks that have a "cheaper feel" to them (nearly always black, in view of other current discussion...). These disks have plastic sleeves that are much thinner and lighter than the blue Sony disks I always use myself. Interestingly enough, the only black disks (hence the only singing disks) I have are the 1.2 beta release disks I receive from C-A! Since the first thing I do with those disks is copy them to working copies, I don't worry an awful lot. In answer to your questions, then, I believe the problem is in the disks themselves, and not in the drives. As you said, their source was a bit of a sleaze... >Should I sacrifice a goat under a new moon? Perhaps. I usually find, however, that sacrificing a slow left-lane driver at a full moon works better (1/2 :-)...
