Details:

hello! i'm having a problem with usb-hdd "Samsung S2 Portable". first of all,
it's partitioned in a such way:

/dev/sdb1: UUID="4492DD7D514F2801" LABEL="svalka" TYPE="ntfs" 
/dev/sdb5: LABEL="backup" UUID="fd81f9f9-efd0-428f-a30f-8405da82b39e"
TYPE="reiserfs"

sdb1 is 400G ntfs partition, sdb2 is extended and sdb5 is logical, 15G
reiserfs

fdisk -l /dev/sdb:

Диск /dev/sdb: 500.1 ГБ, 500107862016 байт

the problem is: grub2 doesn't correctly see my sdb5 partition. i go to
command line and do "ls", ls says:

(hd0) ...smth from my sda... (hd1) (hd1,5) (hd1,1)
error: out of disk

if i say "ls (hd1)", it displays (hd1,5) as "unknown filesystem".
partition table type is "msdos". i partition this hdd with gparted, firstly
there was no extended partition, just sdb1. earlier there was second logical
partition, sdb6, and grub2 didn't see it at all. then i used fdisk and removed
extended partition at all. then recreated it with fdisk and created 15G
logical sdb5 inside. and then mkfs.reiserfs with default params (only set
label). after that i got the same errors as before: "out of disk".
what is intersting, in Linux everything is fine with this drive, all
partitons mount/read/write succesfully, during partitioning i've never got any
errors. the disk is new. both sdb1 and sdb5 partitions are ok due to fsck.
i've even installed grub2 on sdb5 (grub-install
--root-directory=/media/backup /dev/sdb), but when i've tried to boot from
this drive, i've got "error: no such disk" and been dropped to grub-rescue.
now i have grub 1.97.b4 on Ubuntu 9.10. i'm not sure if it's related to fs on
sdb5, so i plan to try with another fs or with empty partition.

below is some additional info...

now i'm not ready to re-partition the whole drive, because i have some GBs of
data on my big ntfs partition, but i will try to place them elsewhere outside
and recreate the whole table later
