Trouble mounting/formating 16g SanDisk USB

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?

*I Have a Acer Aspire M5-581t 6807 
-Intel® Core™ i5-3317U CPU @ 1.70GHz × 4 
-Intel® Ivybridge Mobile
-6gigs of ram 
-20gb ssd 
-500gb hdd
-lintel 4000 graphics
*I'm running Ubuntu 13.04 64 bit

Solution 1:

well i've not seen such error before, but you may try this: it may work

• Format it:

mkfs.ext4 /dev/sdc

For mounting it:

mkdir /media/mountPoint 

 mount /dev/sdc /media/mountPoint 

p.s: Check if device is /dev/sdc or /dev/sdb

Second way to do it (UI):

                 Use **Gparted**

Install it by

 sudo apt-get install gparted

 sudo gparted
