Unable to mount

[BuddyThirteen]

When inserting a USB flash drive (named "Sexy"), I'm getting an error message that indicates the drive can't be mounted.

Error mounting /dev/sdb1 at /media/johnny/Sexy: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb1" "/media/johnny/Sexy"' exited with non-zero exit status 32: 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

running dmesg|tail results in:

And of course it was right when I'd copied a bunch of important stuff to this drive, and I haven't yet gotten to back it up. So yeah.

Is it recoverable, or am I just completely out of luck?

So...?

You could try running fsck on the device? Is it formatted Ext4, by the way? That is what it is being detected as, but usually flash drives are preformatted as Fat32 (vfat).

[BuddyThirteen]

Yes, I reformatted it as ext4 because I needed to create a truecrypt container that was about 6GB.

Running fsck, it says:

fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)
Superblock has an invalid journal (inode 8).
Clear<y>?

So, do I want it to clear?
