Attempted to format drive in question (/dev/sdc2, /dev/sdb2 before
reboot) from ext4 to NTFS, failed to unmount disk 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. Shell format utilites would
actually complain about mounted disks-- the fact the "Disks" was able to
format an in-use, mounted drive is very worrying.
