Hi
thank you so far...
it seems to work now, though the performance is not that great...
(~3MB/s with 100 percent cpu usage when doing a dd from /dev/zero to the
disk), which is not that unexpected...
so the question is, is that a known problem with the hw in genreal and i
have to live with it orsomething i should give a closer look to find 
out what is going wrong?

thanks

yours
albert
