Thanks.  We're currently trying to find out what's actually going on
with all these drives.  At first, drives which got blacklisted aren't
many and made sense (had other problems with NCQ, etc..) but with new
generation drives from many vendors showing the same symptom, we aren't
too sure now.

I'll keep your email in my todo list and add the drive to the blacklist
once the problem is verified.

Thanks.
