Your iPod's Debug Menu
quakeslut writes "Want to access your iPods hidden debug menu with 16 developer tools, including a 'HDD Scan' and various system tests? Just 'restart' your iPod (press and hold the 'menu' and 'play/pause') and when the Apple comes up, press and hold the 'back', 'select' and 'next' buttons (all 3 buttons in the center row). Cool nerd stuff."

here is a picture of the HD test running on a 20 gig iPod.
I would provide more pics, but the test is taking a while to run...
I have a new 20G pod and this works for me. I notice that the newer pods have a RTC as well. This should save some battery life for those of us who use the calendar and alarms.
On many Sony televisions, you access the maintenance menu by turning the TV off, pressing "Display" "5" "Volume +," and turning the TV back on. So yeah, there's a long tradition of hiding service and maintenance features behind obscure keystroke combinations.
Before you try it, though, be aware that you can seriously fuck up your TV if you change a setting by mistake.
I write in my journal
its seems that holding menu+back+play/pause resets the battery..... oops
