Absolutely take this drive back to your dealer.  It has re-allocated
over a thousand sectors.  In my opinion, a drive should be put on a
short-term (~3month) replacement list for the next convenient
opportunity as soon as the first sector gets relocated.  If you get more
relocations in quick succession, replace immediately.

Interesting.  This drive claims to support SCTERC.  I was under the
impression the EARS drives didn't.  Could you please show the output of
"smartctl -l scterc /dev/sdl" ?
