Revealing Original Battery
Revealing Original Battery
The hard disk is connected by a ribbon cable at the top of the iPod, with a foam 'clip' at the bottom to keep it in place. There're no screws, so you can lift the hard disc from the bottom, hinging on the ribbon connection. Try to avoid lifting the hard disc at the top, as this could tug at the cable's connection to the circuit board. With the hard disc lifted up, you can now see the nesting of the iPod battery, surrounded by circuit board. At this point I hadn't dared flatten out the back casing (by opening out the aforementioned case-to-case ribbon cable) but the battery doesn't easily lift out so it's necessary to flatten the case to get good screwdriver leverage on the battery. The battery is held in place with a small amount of adhesive, but with the case laid flat you can gently level it out with a screwdriver. Note that you can't remove it from the case until you've disconnected it from the circuit board, explained with the next photo.
Bad Drive
Bad Drive
This is the extracted original drive. Disk Utility says it can't repair the catalog, and fsck_hfs so far has been unable to help either. I still wonder if results would be different if I could mount it in another machine. It should probably be noted that this drive's serial # matches a list of known bad batches of drives Seagate sold Apple, so I'm surprised it lasted as long as it did.
