RiotousMonk:
Hi All,

I restored my nano-3g again on my macbook, and refilled it with a dd from /dev/zero, then took a dd of the entire device. Â The final .gz file is 7.5 MB.

Please have a look at what I did below, and tell me if that is correct, and let me know should you be interested in the details of the file.

That looks fine. Just upload it somewhere. Don't attach it here on the forum, as space is very limited.

I'm not exactly sure what you mean by Ubuntu not "recognising" your iPod when formatted on OS X, but if you mean you can't mount it, your kernel probably just doesn't have HFS+ support compiled in.

Here is the image dump from my 8GB Â nano-3g.

http://tokyo.moro.us/nano3g_8gb.img.gz

and some pics of the innards from some kind soul.
http://www.ifixit.com/Guide/iPod/iPod-Nano-3rd-Generation

same photos + ipod classic:
http://www.appleinsider.com/articles/07/09/10/a_peek_inside_apples_new_nano_and_classic_ipods_photos.html

cost analysis of the nano-3g, with vague references to makers and spec on some of the chips - maybe useful in trying to figure out which chip is what in the above linked photos (apple branded rather than off the shelf?) : http://www.isuppli.com/news/default.asp?id=8490&m=9&y=2007

jv823md:
As an owner of an iPod Classic 80GB I could of course provide a HDD dump, but that won't help much as the firmware is clearly stored on a separate flash chip. Even if you wipe the entire hard drive, it still boots fine although it doesn't save the settings until you give it a nicely formatted FAT (or HFS) partition again, as the iTunes iPod repair program seems to do additionally to reflashing the firmware.
