Well there are no lvm related file systems.

But, you said you had this....

# mount | grep sdc3
/dev/mapper/HGST_HTS721010A9E630_JR10006P0BSEEF3 on /sdc3 type ext4 (rw,relatime,journal_checksum)

So, the file system defined by /dev/mapper/HGST_HTS721010A9E630_JR10006P0BSEEF3 is mounted on the mount point /sdc3.   /dev/mapper/HGST_HTS721010A9E630_JR10006P0BSEEF3 is probably a link to some thing else which may give a clue.

/dev/mapper, AFAIK, is only used for lvm, part of a RAID, or dm-crypt partitions.

Do you know what this disk is supposed to contain?  If nothing is valuable I'd just wipe it clean and repartition everything.

You mention problems talked about on blogs and things....but don't cite references so nobody can vet the information.
