Does "cat /proc/mount" produce the same result?

Do you see any entry that you cannot identify as a disk you know
(beside the usual proc, sysfs...)? Maybe there is a node in /dev
referring to sdc with another name.

Can you read the disk? E.g. (probably to be done as root)
  dd if=/dev/sdc of=/dev/null count=10
  dd if=/dev/sdc2 of=/dev/null count=10

Can you mount it read-only (-o ro)?
