SATA 0: 200 GB (Windows 7)
SATA 1: 1 GB (Rescatux USB. E.g. Grub mkrescue disk)
SATA 2: 20 GB (SteamOS E.g. Debian)

 From GRUB point of view:

* (hd2,msdos1) is Gnu/Linux root filesystem
* (hd2,msdos2) No such partition
* (hd2,msdos3) No such partition
* (hd2,msdos4) No such partition
* (hd2,msdos5) FATAL: int13_cdrom: function 42. Can't use 64bits lba

 From GNU/Linux point of view:

Disk /dev/sdc: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders, total 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00068a9f

    Device Boot      Start         End      Blocks   Id  System
/dev/sdc1   *        2048    40136703    20067328   83  Linux
/dev/sdc2        40138750    41940991      901121    5  Extended
/dev/sdc5        40138752    41940991      901120   82  Linux swap / Solaris


If I try:

ls (hd2,msdos5)/

from a 2.00-15 system mkrescue image (Super Grub2 Disk 2.00s1-beta6) I get:

error: unknown filesystem.

So, it's ok, because it is not a fatal error.
It would seem that somewhere between 2.00-15 and 2.02~beta2-7 (Debian 
version) the bug arises.

Or maybe the error was before because grub did actually to arise a FATAL 
error and it didn't.


Thank you for any indication on how to make more tests.
