There are a number of different reasons why this information can become corrupted, but in some cases, if the damage isn't severe, it can be corrected using these techniques.

Not really tricky. Pretty logical when you think about there's a pointer to the next free block involved. If you don't update everything...I'm sure you get the idea.
