Here is a picture:

Nice I think I found it. it was attached to the white cog under the lid. I guess I have to super glue it back to the motor spindle ontop Thankz.
Wow, I'm surprised that was the reason for the drives trouble, but since it happened to my drive, I thought it could happen to other drives aswell. I bet the extreme heat of all the spinning and such had melted the glue between the magnet and the spindle motor, which eventually came off.
Make sure you super glue it all the way on and evenly. Then wait for the glue to dry completely. Otherwise the magnet might get kind of loose and end up stuck in an uneven position, causing the disc to be un-secure, especially if the 360 is stood vertically.
This problem happened to me and I had to force the magnet off with a razor (didn't have acetone at the time), and then I had to scrape the superglue on the inside off to get the magnet to fit evenly.
