Opening the iPod can be challenging. Don't get discouraged if it takes you a few tries before the iPod is opened.
Insert a large iPod opening tool into the seam between the plastic front and metal rear panel of the iPod, near the headphone jack. The tool's edge should point towards the metal rear panel to prevent any accidental scratching of the plastic front.
Run the tool along the top seam toward the upper left corner of the iPod. Press the tool into the corner, creating a small gap on the side of the case.




How necessary is it to have the HOLD switch in the locked position? On my iPod the switch is stuck in the unlocked position and I can't force it into locked.
Is locking the iPod for a mechanical reason or an electrical/soft ware reason?
It is for an electrical reason. If the iPod hold switch is kept on, the device will not turn on, thus ensuring the device stays powered off while performing service.
I have a 60 GB iPod photo that needs a new Logic Board. I bought a 30 GB used iPod on eBay and replaced the Logic Board. Now the iPod thinks the hard drive is only 30 GB, when it is really 60 GB. It works, but the hard drive is not recognized for its full size. Sites like this offer a 20 GB and 40 GB logic board...I apparently need 60 GB. Can I bypass this somehow, or do I really need a logic board that is specifically made for 60 GB???
My 30gig drive shows up as a 16.4gig. I can not for the life of me, figure out why this is doing this. Can anyone help? Thanks!
