Matt,
thanks for suggesting smartctl. Ubuntu had loaded a GUI version. It looks
fine on all drives but the smallest (and therefore probably oldest) one. I
had to apt-get install smartmontools to get the command line version. The
GUI was returning almost immediately from the self test with no values for
any test parameters. The command line gave the data below. The error count
kept increasing when I re-ran it. It looks like the drive is trying to
start up and finding a smart mode error. If I just mount the volume (VFAT),
it does not make the sound and the directory appears to work correctly
(virtually nothing left on that drive, anyway). But when I unmount it, and
try to run tests, it starts making the sounds again every minute or so, and
the error count begins to go up again. I guess it is time to shred the
drive. remove it and throw it away.
