Truth Behind the Magic Wiggle

My old click-wheel iPod has been a pain the last year or so. About four times Ive had to take it to the Apple Store to get it fixed due to the sad iPod icon that comes up when I turned it on. Every time I take it in, some Genius Bar guy takes it in back for 30 seconds or so and comes out with the thing working again. I would inquire each time, only to have every Genius give me another cryptic answer, one even referring the technique as a "magic wiggle." Well guess what? Today I took it in again and learned just what is the magic wiggle. This Genius leaked the information that what they are doing back there is the default reset by holding down the top and middle button on the wheel, and while the iPod is resetting, slamminmg the iPod down on a counter. This apparently unscrambles its scrambled hard drive. You can see why they dont want to do this in full view of the public, but you could have told me, Geniuses. You could have told me.
