iPod Hidden Key Combination Commands!!

DISK MODE (push about 10 sec)
Many people overlook the fact that an Apple iPod can be used as a portable data storage device for any type of file. An iPod can double as a FireWire or USB 2.0 hard drive for your computer and is capable of storing anything. This enables you to take data, image, or other file types from your computer and place them onto your iPod very quickly and efficiently. Many people are unaware of these important features and do not understand what the iPod is capable of. In order for your iPod to be able to share non music files with a computer it must be configured so that the disk use mode is on.

DIAGNOSTIC MODE
If you have tried trouble shooting your iPod to no avail, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod. 1. You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. You should not see any orange. Toggle it on and off to be safe.
2. Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
3. The Apple logo will appear and you should feel the hard drive spinning up.
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode.
4. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode.

You can run the following tests on Photo and Video iPods.

If your iPod fails any of these tests, then you might have a hardware problem. You can try to trouble shoot your iPod some more, but there may not be much you can do.
