Just purchased a new Samsung 250 Gig SSD, extern & internal. When I pluged it into my Mint Linux desktop via USB it never showed up or auto mounted. When I tried to run the command 'sudo mount /dev/sdc /mnt' it gave me this error, 'mount: you must specify the filesystem type'. I have yet to format and I have no idea what it is out of the box. What can I do here? Thanks.
