Sorry, sorry, I was 'tuning' the IDE chips in a wrong way. Since ever
and on every machine (~ 50) I'm using

hdparm -c1 /dev/ha[a-d]

to enable fast 32-bit I/O.
But with i820 chipsets, this will corrupt data!!
After 100 tests and reboots I changed to

hdparm -c3 /dev/ha[a-d]

and the world is okay. Thank you Wintel once again, I have never seen
this kind of problem with any ServerWorks or VIA chipset.
