The memtest is now running more than 24h without any errors.
So I think I can presume mem is OK.

i.m.h.o. it now can only be a bad chipset regarding the IDE, the HD itself, or a software bug (sorry I don't want to offend someone).

I did some normal cp en rsync to see if I can reproduce the error, but nothing happened.
Are there some stress-test for the HD, or is there a website where I can more info on what all the errors mean.
