Hmm...

I believe, that a "dd bs=128k count=1000 of=/dev/null" (maybe with
several iseek values) would be sufficient to detect the worst
disadvantages.

That test should be done on at least one box (always the same if
possible), whenever a hard disc is changed (then the box has
changed a little bit), and whenever there is a new release or some
development progress.

May I try, please?

Maybe I should admit, that I damaged my slices and partitions some
days ago, but now everything works fine again... :-))
