USB drive will not mount

I am helping out a friend who has Mint 11 installed onto a USB drive. When booted, it will not auto mount another USB drive, although Disk Utility recognizes the drive. I tried to manual mount using Disk Utility and got the following error.
Error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sdb1 is already mounted on /
mount failed
I tried this with two separate drives and got the same results. In Windows XP, both drives work fine. Here is the output of fdisk. sdc1 is the drive that will not mount.

Any help with this would be appreciated.
