hello! i'm having a problem with usb-hdd "Samsung S2 Portable". first of all, it's partitioned in a such way:
sdb1 is 400G ntfs partition, sdb2 is extended and sdb5 is logical, 15G reiserfs
fdisk -l /dev/sdb:
the problem is: grub2 doesn't correctly see my sdb5 partition. i go to command line and do "ls", ls says:
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...
udevadm info --query=all --name=sdb:
hdparm -I /dev/sdb:
fdisk - x - p:
fdisk - x - d:
lshw:
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
