To do this you have to either do a lot of very deep, very arcane research into the limits and disadvantages of FAT32 – or just take Tarkan’s advice and use the public domain extended format utility he recommends – which runs only on a PC.
Of course you can get round that on a Mac Book by running Windows in a virtual machine, but that may be more trouble than it’s worth.
Ease up the brownish plastic clamp on the battery cable connector and detach the battery.
Many people forget that i Pods are effectively powered on all the time: changing the storage subsystem is something you don’t want to do while the i Pod is active.
A PC: If you are a Mac-only person, then you’ll struggle to complete this job, because one of the vital steps is to format your SSD as a FAT32 device.
This isn’t a problem for small drives – but the whole point of the exercise is to upgrade the storage.
The technique required is to push a sharp blade between the side joint of the front and back covers: look carefully at our finished case to see how the metal casting of the front is shaped underneath the steel stamping of the back – this is the best place to push your blade.
DON’T try to carry on with the blade: you need a wide flat implement in there to lever the back away evenly.
On the other hand, while the back is not clipped on, this will probably be your only chance to put in a new battery.
The reason not to – which won out in the end for us – is that it’s impossible to gauge the quality of third-party replacement i Pod batteries.
