Bug#533898: grub-common: "grub-probe --device /dev/hda4 --target=drive" returns (hd0, 4), should return (hd0, 3)

[Lutz Lehmann]

Package: grub-common
Version: 1.97~beta3-1~bpo50+1
Followup-For: Bug #533898

Hello,

see subject. Perhaps too trivial, but in the opening post the grub-probe command should return (hd0,3) instead of (hd0,4). Grub counts from 0, the dev system from 1, so /dev/hda1 translates to (hd0,0) etc.

On another computer with Debian unstable in a current version, /dev/sda4 is translatet into (hd0, msdos4), obviously comming from the succeeding fat32 partition. The partition table there is
