iPod diagnostics

I dropped my iPod some days ago (aahhhh!!!) and tonight I experienced the first problems because of it, one of the songs wouldn’t open.

So I restored the iPod software, thrashing all the music on it and enjoy the fresh start. Then I figured that it would be nice if I could run some sort of hard disk scan, searched on the net and found the coolest thing; the iPod bhas uilt in diagnostics!!
On my 4G iPod I can enter the diagnostics menu by pressing "BACK" & "SELECT" button while the iPod restarting. It gives me several check, including a hard disk scan! WOW 🙂
Here‘s a site with some more info!
