Issues with large drives going back to PIO

[Peter Kieser]

Hello.

A few months ago (May) to be exact, Søren posted a patch (
http://lists.freebsd.org/pipermail/freebsd-current/2003-May/003275.html
) to the FreeBSD-current mailing list relating to IDE drives over a certian
size having issues with falling back to PIO mode and other things. This
patch was commited, and is currently in 5.1-RELEASE, and my friend told me
to try applying to the patch to fix the problem (although the patch was
already commited). There does NOT appear to be anything wrong with the
drives, as I have run tests on them and stuck them in another FreeBSD
5.1-RELEASE box, and the problem seems to disappear.

The error I'm getting is..:

The drives are 120GB Maxtor 7200RPM with 2MB cache, I have 3 of them; and I
have experienced the same error with FreeBSD 5.1-RELEASE, and 4.8-RELEASE
(4.8, which always made the drives go back to PIO mode no matter what). The
board is a Asus P4SDX:

I have not had the box crash, or anything in that matter. Just very slow
access to the drives because they have switched back to PIO; and I have to
force them back with atacontrol to regain the speed.

Any suggestions, comments, tips? Should I be trying to replace the drive?
How can I do that if MaxDiag doesn't give me an error code so I can get the
drives RMAed?

Cheers,
