Use lsblk to see if there's in fact still a device node for sdc. And then you can try:

dd if=/dev/sdc count=1 2>/dev/null | hexdump -C

That will report the contents of LBA 0, a.k.a. the MBR. 

What device did the SD card come from and how big is it? Is it SD or SDXC? The SDXC spec makes exFAT the volume format for these cards, which is proprietary. There are one or two floss projects that enable support for exFAT. But when I do a yum search, I get no results. I don't have rpmfusion or any 3rd party repos enabled, however. So I'd look there.
