I know it's not likely to be schedule issue, but it doesn't hurt to ask :-) And please don't tell me it's hardware, I've changed a few motherboards (all VIA 8235/8237) and different manufacturer / types / firmware revisions HDDs since 5.0 because after an update or another some specific combination ceased to work. It seems some kind of regression introduced sometime after 5.3 release. > Did you try sos' new driver yet? Nope, I didn't have the time. Given my luck with ata it is rather prudent to back-up ~200GB before trying. -- IOnut Unregistered ;) FreeBSD "user"
