Not without you telling us how it is partitioned, how it is mounted and what filesystem(s) it is formatted with

Of course... Plug in your USB thingy, wait a moment, (choose "Open" if in doubt) then, in a terminal, konsole or whatever try these commands
Code:
fdisk -l
which will tell you about the partitions linux recognises, and how they they are formatted. Then,
Code:
mount
will tell you about how they are, or aren't, mounted

Note: you may have to be root for these commands to work (depends on your distro, and its security settings).
Just work out how to make these commands work (experiment a little), and post their output here.

The [Search] button on this page is quite useful, as may be the "related threads" list at the bottom of this page,

This doesn't look like a partition table
Probably you selected the wrong device.

There is something wrong with the partition table on sdb.
I do not think this is fixable other than by re-partioning it, and then reformatting it.
