Actually /dev/sdc2 is mount ls /run/media/user
Sorry, this is wrong /dev/sdc on /run/media/user/Data Logger type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)
/dev/sdc 3856 0 3856 0% /run/media/user/Data Logger
mount /dev/sdc1 /mnt/tmp mount: /mnt/tmp: special device /dev/sdc1 does not exist. dmesg(1) may have more information after failed mount system call
sdc2, sdc3 and sdc4 respond the same way.
Perhaps someone created a partition table on the device, but then wrote a FAT32 filesystem to the raw device, and the bits on the only filesystem look close enough like filesystem entries to confuse tools?
