  Attempted to format partition in question (/dev/sdc2, /dev/sdb2 before
  reboot) from ext4 to NTFS, failed to unmount partition beforehand.
  Admittably a failure in proper user policy; but a frontend graphical
  program like "Disks" should know better than to have actually tried to
  preform said operation without doing an unmount first. Result was a
  partition which read 16EB (exabyte) ext3/ext4 in caja shell properties
  window. Attempt to unmount via caja shell resulted in kernel panic :(

  Clearly this is a very serious issue; anybody working on disk
  partioning could potentially make this mistake. Terminal format
  utilites would actually complain about mounted partitions-- the fact
  the "Disks" was able to format an in-use, mounted partition is very
  worrying.
