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.

In those examples the drive was mounting just fine and mounting where it should, I'M not that luck, take a look.

Here's what I get with the HD plugged in:

Any ideas?

Looks like it's coming up as sg6. Tail dmesg as you plug it in to be sure.

Here's what I got:

garrett@mint-desktop ~ $ dmesg | tail
[11392.002016] sd 6:0:0:0: [sdc] Write Protect is off

I got it with sudo mkfs -t ext4 /dev/sdc

Thanks, I wouldn't have noticed that it was sdc with the dmesg command you gave me, didn't know that one. Like you it appeared to me that it was sg6.
