I have been playing with a selection of these drives recently (well,
actually 3 of them) and they all have the same problem ...

After turning them on, make the disk work a bit (SCSI evaluator
for example) - when the test has finished just watch the drive ...
after a minute or two you will here the drive stepping across the
disk all by itself (the light won't be on) - then there will
be a horrible clunk and this tinkling noise followed by the thump
which will then repeat every 30 seconds or so - if you force the machine
to access the disk, the Mac will crash !

If, however, you let the drive warm up for half an hour before
you use it, all will be fine - this seems to be a heat related
problem (all drives were either in their fan-cooled cases or in
the open) and they all do it, repeatably.

Has anyone else run across this before, I know that they
have sold loads of these, but maybe not everybody uses the drive
vigourously after switch-on?

Comments anyone ?
