Information & Setup
This modification is completely computer-side, meaning that you will have to change no settings on your Zune. This is a good thing and a bad thing. The good news is that there is no worry about voiding your Zune's warranty, but the bad news is that you must complete this mod on every computer you with to use to access your Zune as a portable hard drive.
The only setup required is that your Zune is NOT connected and the Zune Software is NOT running
And remember, ZuneMods.net or DarkZune.com is not responsible for any possible problems that may occur. Changing your registry is something you should perform at your own risk, because if you change the wrong values your computer may not function properly.
Step 1
Hit the "Start" button and choose "Run".
In the Run Menu type "regedit", and hit "OK"
Step 2
Now, a window should pop-up and on the top it should read "registry Editor". Now in that window use the left side browser to find "HKEY_LOCAL_MACHINE\System\ControlSet001\Enum\USB\ ". Once you have completed that your screen should look like the following:
Step 3
Right click on the folder titled "USB" that you just found and select "Find".
In the "Find" window search for "PortableDeviceNameSpace"
Step 4
The right section of the window should now look like the following: The next step is changing the following values: Change:"EnableLegacySupport" from "0" to "1" Change:"ShowInShell" from "0" to "1" Change:"PortableDeviceNameSpaceExcludeFromShell" from "1" to "0"
Step 5
Close all windows and connect your Zune. Now when you browse to "My Computer" it should read your Zune as a device that you can browse into, and drag and drop files into.
In order to access files freely on your Zune, you must make sure that the Zune software is RUNNING. If you try to access your Zune as a hard disk while the Zune software is closed, it will give you a permission error.
Conclusion
Now remember, this must be done on every computer you wish to use to access your Zune. I know this article may look long but once you have done it once or twice it really only takes a minute or two to do it.
Immediately I noticed a major convenience, the "Music" folder in the Zune organizes your music by artist. This means that it is VERY easy to transfer music and songs to a friends computer.

Found the alternate method over on the other board but it doesnt work either. Not sure if I am doing something wrong or if it has to do with Vista. Oh well, no big deal.
Hmm.. I also tried the alternate method and the patch. Niether work.. but apparently, even if setup correctly, there are many problems with it, such as only being able to sync once and that new added items arent picked up...
Ok, found the problem. The guide says to modify the registry values below "HKEY_LOCAL_MACHINE\System\ControlSet001\Enum\USB\ ".
This did not work for me under Vista. I searched around and found a post in another forum to use HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB\". this worked for me. I have two icons listed now so I need to get rid of one but at least its working now.
I made the hacks on original Zune firmware in ControlSet001 and ControlSet 002. Could see my Zune in My Computer, but could not really use it as hard drive. Could see my files. The new firmware disabled that. So I went to CurrentControlSet and made the hacks there. Now I can see my Zune once again in My Computer, but can't really use it as hard drive. If I double click on a song it doesn't play, but it copies it under User/Local Settings/Temp.
