This is because of my nForce 4 Hardware RAID 0 (i.e. dmraid).
Linux sees 2 disks (sda,sdb) and the partition table of the first is for
the 2 disks combined.
Both disk have only 80 GB but both combined have 160 GB.

Oh I should have said in my case.
The BIOS presents GRUB only one (hd0) for the combined 2 disks.
Whereas the ata.mod from Marco sees both (well it fails to detect one
but in theory)
The BIOS does handle the RAID 0 for booting, but just for that.
As soon as the OS takes over it has to handle it.

Yes it isn't that important,
as I already said I only want to find a clean solution for the long
term.
The current way is better then before, but at least I don't like it to
have a error message shown more then needed.

This doestn't look that good either ;)
