You can use file to inspect the contents of the device:
# file -s /dev/sdc1
E.g.:
# file -s /dev/sda1
/dev/sda1: Linux rev 1.0 ext3 filesystem data (needs journal recovery)
# file -s /dev/sdc1
/dev/sdc1: x86 boot sector, code offset 0x3c, OEM-ID " mkdosfs",
sectors/cluster 4, root entries 512, Media descriptor 0xf8,
sectors/FAT 125, heads 3, sectors 127848 (volumes > 32 MB) , serial
number 0x4b21069a, label: " ", FAT (16 bit)
The '-s' is needed to tell file to look at the device content and not
just report that this is a block device node.
The blkid command (part of util-linux) will also give useful
information on what devices contain:
# blkid /dev/sdc1
/dev/sdc1: UUID="4B21-069A" TYPE="msdos"
