When we got it open, we discovered that it was completely caked, and I mean to the BRIM, with dust, lint, cigarette ash, etc. A simple can of air could not have done the job alone. We had to vacuum it out.

Once it was all clean, we hooked it back up, and it worked like a charm.

I've also found everything from tools, to food, to various parts just laying inside cases. I've also seen people try to use credit cards in their floppy drives.
