USB stick won't mount ("wrong fs type, bad option, bad superblock ...")

dmesg happily says my USB memory stick is found and ready at /dev/sdb. It's formatted in Windows as FAT. Yet it gives the following error for three differently formulated mount commands:

# mount /dev/sdb1 /mnt/usb1
# mount -t vfat /dev/sdb1 /mnt/usb1
# mount -t vfat /dev/sdb /mnt/usb1
mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage, or other error

I've also tried reformatting (FAT and FAT32) a couple of time.

The same command have worked for the same memory stick on another system/machine.

Thanks in advance for any ideas!

What is the output from running

Code:

fdisk -l

when the USB drive is inserted? Note that's a lowercase "L"

# fdisk -l
[...]
/dev/sdb1 1 1010 1033199 6 FAT16
# mount /dev/sdb1 /mnt/usb1
mount: wrong fs type, bad option, bad superblock
on /dev/sdb1, missing codepage, or other error

How about

Code:

mount -t msdos /dev/sdb1 /mnt/usb1

Thank you for that, syg00. You made me take a look at dmesg, which said that codepage 437 couldn't be found. Then I remembered disabling something like that (apparently precisely that) in Native Language Support under File Systems in the kernel configuration (I'm running Gentoo). I'm right now recompiling and will edit this message when done.

Edit: And it works.
