Err, unfortiunatly no, both Diamond Max 6800 ATA/33 & ATA/66 series (eg.
91000D8, 91360U4), seem to be affected with timing issues as well, on the
HPT366... (though they seem to work okay on the Promise Ultra66 (PDC 20262).
I also own an ATA/33 Seagate ST36531A with screwy DMA transfers on the HPT366
as well :-(
