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.

prudent to back-up ~200GB before trying.
