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

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...

You cannot mount an extended partition. It looks like you are using LVM in Ubuntu. You would need to import the LVM configuration on the new system.

Here is a link:

Well the error says "mount: wrong fs type, bad option, bad superblock on /dev/hdb2, missing codepage or other error." Are you sure /dev/hdb2 has the ext2 filesystem? You can mount paritions without specifing the filesystem type, try that.

Nevermind, not only did tells beat me to it, his answer is alot better
