As promised, I've copied the first 48MB of the disk + 2M at the
beginning of each partition

http://xoomer.alice.it/enodetti/ipod/ipod.sda.bz2
http://xoomer.alice.it/enodetti/ipod/ipod.sda1.bz2
http://xoomer.alice.it/enodetti/ipod/ipod.sda2.bz2

respectively from

/dev/sda
/dev/sda1
/dev/sda2

using

dd if=/dev/sda of=ipod.sda bs=1M count=48
dd if=/dev/sda1 of=ipod.sda1 bs=1M count=2
dd if=/dev/sda2 of=ipod.sda2 bs=1M count=2

If you need a bigger file, I will need to find a different host. I've
tried with 64MB but I could not upload it.
The output of fdisk is

[root at thinkpad tmp]# /sbin/fdisk /dev/sda
Note: sector size is 2048 (not 512)

The number of cylinders for this disk is set to 2432.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 2432 cylinders
Units = cylinders of 16065 * 2048 = 32901120 bytes

and this is what "file" says about the 3 files

ipod.sda1:    data

ipod1.sda: x86 boot sector, code offset 0x58, OEM-ID "MSDOS5.0",

Hope this helps

Cheers
