Toy Story Delete Disaster

We've all been there.  You're finishing up a paper or project for school the night before it's due but when you try to open it's gone.  You don't know where it went, you might have accidentally deleted it, saved over it, or aliens hijacked your computer and messed with your files. Either way you are screwed.  You know the feeling. 

We'll you're not alone.  The folks at Disney Pixar had that same problem with Toy Story 2.  It was one of the first few completely computer animated films. So it was a fairly new process and they almost lost everything when their computer started deleting the films files.  Here's a video of what happened.
