Yup. That looks a little worrying. You'll get people say "oh that's not
much", and if that doesn't change in a month or two's usage they're
probably right, but if you don't monitor those errors and have a long
term feel for them it could all go pear-shaped very quickly. I wouldn't
trust that drive unless I was confident that figure wasn't changing much.

Force-assembling the array ... if you can copy that disk, use the
original to force-assemble, because it will force a read error and a
raid recovery. If you used the copy, you will get a blank sector and no
read error to force a recovery which will likely corrupt your data. (And
if things go wrong, it probably won't make much difference whether
you're trying to recover from the original or a copy).

If you can, when swapping out the WD and the dodgy Seagate, use the
--replace syntax for mdadm, it'll reduce stress on the array, and keep
redundancy.

Cheers,
Wol
