LinuxQuestions.org - Problems mounting Ubuntu HD in Gentoo

A little background. After using Ubuntu on a second HD and dual booting it with XP for a while, i found i was never using XP and ubuntu just wasn't configurable enough SO... i installed gentoo on my XP(80gig primary) HD with the view to getting my files off the Ubuntu disk (10gig slave) and then installing Win2k purely for gaming.

BUT i seem to be having problems getting the Ubuntu drive to mount

# mount -t ext2 /dev/hdb2 /mnt/ubuntu
gives

mount: wrong fs type, bad option, bad superblock on /dev/hdb2,
missing codepage or other error
(aren't you trying to mount an extended partition,
instead of some logical partition inside?)
In some cases useful info is found in syslog - try
dmesg | tail or so

fdisk gives me this:

Disk /dev/hdb: 10.0 GB, 10005037056 bytes
255 heads, 63 sectors/track, 1216 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdb1 * 1 31 248976 83 Linux
/dev/hdb2 32 1216 9518512+ 5 Extended
/dev/hdb5 32 1216 9518481 8e Linux LVM

I originally just created an entry for it in fstab which reads:

# <fs> <mountpoint> <type> <opts> <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda1 /boot reiserfs noauto,noatime,notail 0 2
/dev/hda3 / reiserfs noatime 0 1
/dev/hda2 none swap sw 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
/dev/hdb2 /mnt/ubuntu ext3 auto,user 0 1

I'm probably just trying to do something really stupid and obvious, i know but any help would be appreciated...
