Hi everybody!

I finally solved my problem. After some more test, I was finally able to reproduce the
problem under Linux 2.4 too. My Test had to run over 10 hours and many gigabytes of copied
data until the same disk corruption occured. It seemed that the Linux kernel 2.6 triggered
the problem faster, because it did more stress on the hardware.

After that, I tried RAID on this harddisks on an external IDE controller with a different
chipset with no success either. Finally I replaced my cheap mainboard (AsRock K7VT4A+) by
an expensive MSI mainboard and everthing works fine.


As somebody else on this list already stated:

~ NEVER buy cheap hardware, if you want to run RAID on it!


Linux RAID may have some bugs, but it seems to be stable, after all!
Never trust cheap hardware :-)


Thanks for all the help,
