SMART

Eben King
My friend gave me a used USB HD, so before mounting it I scanned it with
gsmartcontrol (a wrapper for smartctl).  All of the parameters came up
either Old_age or Pre-fail.  Is there a way to do a low-level format and
start fresh, or am I stuck with how it is?  No data is on the disk, so
whatever is done to it causes no loss.

I try to wipe any used drive I get.  I've used DBAN http://www.dban.org/
for years, it should overwrite every(*) block of the drive several times.
REMOVE ALL DRIVES you don't want destroyed before booting.

You can also do it be hand, as discussed here:
        https://wiki.archlinux.org/index.php/Securely_wipe_disk


If you run it a couple times, you may kill the drive, which would be good
to know.  

If you can remove the harddrive from the USB enclosure and connect it
directly, you may get improved performance (faster).

This is the TYPE of the attribute. They will *always* be either Old_age or
Pre-fail, period. The part you want to pay attention to is the WHEN_FAILED and
self-test results, which look good in your paste.
