zivan56:
Here is an xml file from the hard disk (devcert.dat):

[EDIT: file moved to attachment]

Does this give any clues or keys?  I guess these are known already...
I have also zipped the filesystem and you can get it here:

zivan56:
I guess I forgot to mention that the filesystem appears to have unsigned files with executable binary code (relating to booting/memory/disk checks).  Maybe someone could have a look at that?

Bagder:
The file 'zconfig.dat' contains several strings mentioning TFTP which I find interesting. You aware of any functionality in the Zune that uses TFTP?

NicolasP:
Track sharing over wifi maybe?

Bagder:
TFTP is often used for booting stuff why I'm curious. There are also others strings hinting about this possibility, like:

"SendBootme()::Error on SendUDP() call"

Further research on the "recovery.bin" file shows that it starts with B000FF \n which according to
this page is a file "generated by microsofts romtools". And the description there seems to match the initial bytes in that file. It mentions a 32 bit start address and length following that seven byte marker and there we see 80080000 and 00121C60 (little endian). Another funny thing is that if we run 'strings -el' on that image we get to see "0x80080000" and "0x00121C60" stored...

It is worth noticing that 0x00121C60 is significantly bigger than the recovery.bin file. 45873 bytes bigger to be exact.

Update: zivan56's 53MB fat dump is now also available here => http://daniel.haxx.se/rockbox/zune-tfat.zip
