I've seen this on Western Digital and Seagate drives as well.

I have used the "wipe drive" functionality in each drive's diagnostic
utilities and used dd to zero the entire drive as well. The drives
still report problems.
Unfortunately at this point I usually just throw them out, which is
terribly wasteful but I can't trust them for important data and I
can't get the manufacturer to replace them without an actual failure
of their diagnostic tools.
