My baby sister decided it would be smart to open the disc drive and step on it to use it as a stepping stool to climb the rest of the entertainment unit/tv stand.

The drive appears to be stuck, as my father pushed the tray back in, and wont open. How much will it cost to fix this or is there a DIY fix?

If it helps any, its a Halo edition xbox.... we'd had it for just over a year or so when she broke it. Everything else runs just fine.

Thanks a bunch in advance!
