If you're not sure, whether its your external USB drive, you may check
with `dmesg` and see how it is initialized. I can't suggest a good grep
pattern, but you should look for lines where 'sdb' first appears and
then several lines above there might be usb-storage, usbcore messages,
similar to this:

A possible test would be to boot from live CD/USB and see how the
machine performs. If it seems usable, including reading files from an
internal HDD, then a fresh install might improve things.
