It only exists on certain filesystem types.  Its purpose is to have some
preallocated disk blocks so that e2fsck won't have to allocate blocks
when it's trying to recover files in case of some kind of problem.  Thus
it's not something you need often, but it should exist for reliability.

Use "cd /mnt/data && sudo mklost+found" to recreate it.
