I've hit this problem too in the latest Feisty release (5).
I have three drives which are labelled by Linux and grub in the following manner:
Drive type Linux grub SATA-1 /dev/sda ?? SATA-2 /dev/sdb /dev/sda (this is my boot disk) SATA-2 /dev/sdc ??
The BIOS lists them in with the first SATA-2 drive first. I don't believe I have any control over ordering the SATA drives in the BIOS.
I don't actually know what devices grub assigns to the other drives.
