Well, that sent me on a ~1 1/2 hour journey.
I have an old 2nd gen iPod that doesn't work anymore (it was my first Apple product and ultimately what brought me to this site), so you got me thinking what it would take to get it back up and running again. Unfortunately, I stopped using it when the headphone jack broke off, so first thing would be to find a working logic board, then upgrade the battery and put in a CF/SD reader.
Nice. Any reason why you opted to put in a new hard drive instead of upgrading to a CF or SD card?
