IIRC, the seatools just run the smart tools that come on CentOS/Linux.
Not the same as those on the DOS tools version. It's been several
months, but barring memory failures (mine, not the computer's ;-) I
ended up downloading the DOS ones so that I could do the repair and run
the "real magilla".

Try the DOS version. I bet the lack of that support is in the standard
*IX smart tools, not the drive.

If all drives left the factory in great shape, it is natural that the
older ones would show an error first. Often just a "weak" spot or two
that passed mfg tests and finally failed as they aged. That's why I
don't worry about them (I don't have data center servers to the world
here at home) as long as the repair utilities run successfully and then
no more show up for a long time. If they start coming in frequent
bursts, then it's time to act.
BTW, most warranty replacements are "reconditioned" drives that have
nothing more than diagnostics run and bad sectors reassigned. As long as
total capacity still meets advertised and the mechanics/electrics and
media (high %) are still good, they'll ship them.
