trouble mounting jfs hdd
 

I'm running Ubuntu (I think Breezy).
My second hard drive (SATA), formatted JFS doesn't mount.

Fstab entry:

/dev/sdb1 /video jfs defaults 0 0

then, when i use the command prompt i get:

$ sudo mount -t jfs /dev/sdb1 /video
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

once I run fsck.jfs, which comes back clean, and re-run the above command, it mount OK.

Any ideas as to what is wrong?
