I have three harddisk at my labtop, all with ext2 and ext3 filesystems, one internal and two USB. I would like to install grub in the bootsector of an USB harddisk. If I plugin the USB disk the partions are automatically recognized and mounted, but grub does not recognize the filesystems at hd2: grub> root (hd0, Possible partitions are: Partition num: 0, Filesystem type unknown, partition type 0xde Partition num: 1, Filesystem type is ext2fs, partition type 0x83 Partition num: 2, Filesystem type is fat, partition type 0x1c grub> root (hd1, Possible partitions are: Partition num: 0, Filesystem type is ext2fs, partition type 0x83 Partition num: 1, Filesystem type unknown, partition type 0x82 Partition num: 2, Filesystem type is ext2fs, partition type 0x83 grub> root (hd2, Possible partitions are: Partition num: 0, Filesystem type unknown, partition type 0x83 Partition num: 1, Filesystem type unknown, partition type 0x82 Partition num: 2, Filesystem type unknown, partition type 0x83 root@guenther:/home/guenther(7)# df -T Dateisystem Typ 1K‐Blöcke Benutzt Verfügbar Ben% Eingehängt auf /dev/sda2 ext3 54591040 30614788 21158452 60% / varrun tmpfs 512380 92 512288 1% /var/run varlock tmpfs 512380 0 512380 0% /var/lock udev tmpfs 512380 76 512304 1% /dev devshm tmpfs 512380 52 512328 1% /dev/shm lrm tmpfs 512380 1852 510528 1% /lib/modules/2.6.24-24-lpia/volatile /dev/sdb1 ext2 132206 15483 109897 13% /media/disk /dev/sdb3 ext3 74480096 12369932 58356580 18% /media/disk-1 /dev/sde1 ext2 1083488 15312 1013568 2% /media/disk-2 /dev/sde3 ext3 109210020 25615564 78090588 25% /media/disk-3 Any idea?

Sorry for the different version of this bugs. When I entered the bug, bugs.gentoo.org complains about "error with exec -T", so I tried once more. There is still a further difference between the disks with recognized filesystems and the disk where the filesystem is not recognized. The first disks have sector size of 512 bytes, where the latter has 4096 as reported by parted or fdisk. root@guenther:/home/guenther(21)# fdisk -l /dev/sdb Platte /dev/sdb: 80.0 GByte, 80026361344 Byte 255 Köpfe, 63 Sektoren/Spuren, 9729 Zylinder Einheiten = Zylinder von 16065 × 512 = 8225280 Bytes Disk identifier: 0xad0cca3d Gerät boot.

Not all parts of GNU Parted support this at the moment, and the working code is HIGHLY EXPERIMENTAL. Could this be the reason for grub issue?
I am now convinced that the sector size of 4096 Bytes is the reason that grub is not working with my new harddisk. See also http://savannah.gnu.org/bugs/?22138 Regards
Please post your 'emerge --info' output, and then this bug can be assigned to gentoo base-system team.

I think this would need major changes to fix.
Not reproduceable with 4K sectors hard drives and sys-boot/grub-0.97-r12. Closing this as OBSOLETE
