It's obvious from the error message that there isn't a partition table on the
device, since /dev/sdc is *mounted*.

Your user probably doesn't have permissions to read or write to /dev/sdc, so
you'll have to run the mke2fs command as root if you want to remake the
filesystem. Users don't usually have direct read/write access to disk
devices, because if they had that access, they could bypass/change the
permissions system and the filesystem.
My first message said "if it already has a filesystem on it, you can do
"tune2fs -L A_NEW_LABEL /dev/whatever". You should be able to run tune2fs on
a mounted filesystem as well. Did you not see that part of the message?
Well, a lot of people appear to only skim the first paragraph of things....
