Default Data recover help

Over the weekend my virtual debian lenny machine in a data centre failed to reboot having suffered damage to the file system.

A new debian lenny machine has now been made and the hard disk (san) of the old one has been attached as /dev/sdb2

The fstab look like this:
Code:
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda2       /               ext3    errors=remount-ro,usrquota,grpquota 0       1
/dev/sdb2       /mnt/oldfs      ext3    defaults        0       0
/dev/sda1       none            swap    sw              0       0
/dev/hda        /media/cdrom0   udf,iso9660 user,noauto     0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0
and I've been trying to mount it like this:
Code:
mount /dev/sdb2 /mnt/oldfs
In that directory I see a lost+found directory and another directory called orig. The lost+found directory has many files like #23424.

There is nothing in the orig directory.

This is the result of df -h
Code:
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2             9.4G  2.3G  6.7G  26% /
tmpfs                 503M     0  503M   0% /lib/init/rw
udev                   10M  596K  9.5M   6% /dev
tmpfs                 503M     0  503M   0% /dev/shm
/dev/sdb2             9.4G  3.9G  5.1G  44% /mnt/oldfs
With sdb2 being the old file system gives me hope that the information is still there.

It seems the directory structure is missing. I'm desperate to rescue files from the file system.

I've tried fsck on the sdb2 when it's unmounted but it doesn't report any errors.

Can anyone help me recover these files please?

No, the first link seems to be a software package for £79 that I would struggle to get into a data centre.

The second doesn't seem be related to my issue...
