They are created after a fsck is performed to place unknown files or files without a corresponding descriptor/inode, etc.

Something along those lines, maybe someone else can explain it better than I did.

well just to add to what trickykid said, and just to simplify what was said, when your system crashes you have an option to run fsck at bootup, which is the equivalent to running scandisk in windows...and as you know it doesn't only run when your machine is shutdown uncleanly, cause you can run it whenever you want...
so, whenever it does run, if fsck finds lost file fragments, it knows it can use the reserved inodes to safely relink them back into the filesystem..
What's an inode? Think of an inode as the tiniest part of a disk that can be assigned to hold your stuff -- parts of files, parts of directories, etc. They are usually 4k, but you can specify the size when creating a partition.
so if you lose data mysteriously, then check the lost+found to see if was placed in there....you have to be root to access this directory
