Suggest 'fdisk /dev/sdb' to check out the partition table on the unmounted device - make a back-up first.
I have a 128 MByte '3-inch' USB flash drive that occasionally ends up with a thrashed partition table - although I always unmount and eject it properly. I've tried various file-systems on it - VFAT, ReiserFS, ext2, ext3 - but so far no cure.

There is a very good chance that /dev/sdb contains a file > system. Try it before saying it won't work.
