I was wondering if a reformat might be possible but if it requires the
nuclear option so be it. LOL! I've only had to dd a handful of times so
searched and found this command to zero a drive. Will that get the job
done? Any idea how long that might take on a 1 TB drive? There is
cost|benefit|aggravation to consider . . .
dd if=/dev/zero bs=1M of=/dev/sda
In any case, I'll wait till the dock arrives for further testing to make
that decision.
Thanks again. Nice to see that you're still hanging around the campfire
. . . :)

as you write them. The various disk tools will then tell you what the
overall health of the drive is.

Thanks Bruce . . .
Unfortunately, I don't have spare 1 TB drives laying around. Since
that
drive is an exact copy of another still working drive, no critical
data
has been lost so no need to copy files.
I'm guessing that this failure is beyond fsck . . .
