This disk has a pretty high count of reallocated sectors, plus a lot
of other errors.  I recommend to replace it ASAP.  It is not worth
further investigation - this drive has reached EOL.

This disk also has stored a number of errors, but it does not look
as bad as the first one.  However, there are errors.  I would
replace it as well.
