I'm having trouble mounting or formating my 16gig SanDisk USB. When I run

sudo fdisk -l

I get this return

Disk /dev/sdc: 16.0 GB, 16008609792 bytes

64 heads, 32 sectors/track, 15267 cylinders, total 31266816 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00041d5f

and when I use the Disks Utility to try and format the device I get this error

What would be the best way to mount this device, or format it so it can be readily available every time I plug it in? Is there something else hindering this device from mounting that I am not aware of?
