What we really need for the harddrive hack is some way to mimic the signal sent to the Zune when the Zune software starts up (duh!)
What I did (I know I'm not the first) was track what was going back and forth between the computer and the Zune with a USB Sniffer (starting when I plugged it in and through a sync). I got lots of useful data out of it, but I don't know how to use any of it, and I certainly don't know how to write a program to mimic it. I am posting it here in hopes that someone who knows what they're doing with this kind of thing will take this information and use it to write a totally kick-ass Zune Syncing (but not really) program. I am attaching the info in the form of a .jpg. Once you download it, change the file extension to .usblog. Then, open it up using a USB Sniffing program like Snoopy Pro (
http://sourceforge.net/projects/usbsnoop/).
I think it is the 4th "down" when the computer sends the Zune the signal to sync... but as I said, I'm no expert. Could someone please have a look at this and figure out if it can be used in a mimicing program?
