The response to an unrecoverable sector shouldn't be 51/04 if the
flush fails, it should be 51/10 or 51/40.
51/04 would be the response if the FLUSH CACHE command was issued when
there were still outstanding NCQ commands active.

Tejun: I see we have another thread as well with FLUSH errors.
I really doubt that these are bad drives.
There's very likely a bug in libata / LLD there someplace.
