What kind of external box is this? Could they have used lvm or md
internally to create your volume? I think some of those units are Linux
under the hood.
You could investigate the USB with lsusb, and take a look at the
available disks: ls -l /dev/sd*
I think the maximal mount count would invoke fsck, right?

e2fsck: No such file or directory while trying to open /dev/sdb1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

*3-2-1 for those that don't remember*
o *keeping 3 copies of any important file (a primary and two backups)*
o *2 different media types (such as hard drive and optical media),
to protect against different types of hazards.*
o *1 copy should be stored offsite (or at least offline).*
