Corrupt O/s, Need To Restore From Original Drive

O/S was corrupt so I had to do a reload on a new drive. I'm trying to mount original drive (already connected as 2nd) but it is not showing up in df -h


Code:
root@server080 [~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 145G 2.5G 135G 2% /
/dev/sda1 99M 12M 83M 12% /boot
none 252M 0 252M 0% /dev/shm
/usr/tmpDSK 485M 11M 449M 3% /tmp
/tmp 485M 11M 449M 3% /var/tmp
/dev/sdb1 99M 12M 83M 12% /backup
root@server080 [~]# e2label /dev/sdb1
/boot1

root@server080 [~]# dumpe2fs /dev/sdb1 | grep -i superblock
