Ok, that did not work, but I have more info,here's the messages I get
when attempting to mount the drive and running fsck:

myth at myth:~$ sudo mount /dev/sdb1 /var/lib/mythtv
[sudo] password for myth:
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
        missing codepage or helper program, or other error
        In some cases useful info is found in syslog - try
        dmesg | tail  or so

myth at myth:~$ fsck -C -f /dev/sdb1
fsck from util-linux 2.20.1
fsck: fsck.jfs: not found
fsck: error 2 while executing fsck.jfs for /dev/sdb1
myth at myth:~$

Is this telling me that I need to install fsck.jfs or is it saying  
something else?
