[HD2 Android SD Development] shamez23:
You don't need partitioning for Windows Mobile.

Just put your Android folder on your SD card. That is all you need for Android as a system. Windows will see that folder like it can see any other folder you put onto your card. And Android will see all folders on your SD card aswell.

Both systems can use your SD card fully, without any partitioning.

In your Andorid folder is a file named data.img. That is your Android system. You might say that file, in a way, is your Android partition.

With a file explorer you can create folders in that file while you are using Android.

But you can also create those folders by putting a folder named "root" into your Android folder. Files contained in the "root" folder will be copied into the data.img during booting.

If you want to use your own ringtones, those ringtones have to be in a special place so Android recognizes them as ringtones.

That's what you do with

/sdcard/android/root/system/media/audio/notifications/YourAwesomeWhateverNameHere.mp3

If you follow these instructions a folder named "media" will be created in the existing "system" folder, that is inside the data.img file. There will also be created a folder named "audio" inside the "media" folder and inside the "audio" folder will be a folder named "notifications". Android needs those folders in this order and place to recognize the audio file you want to use as notification ringtone.

The folders and the ringtone will get copied into the data.img when you boot into Android.

The folders and the audio file will now be inside the data.img file and also inside the Android folder, where you copied them to, in the first place.

If you are booting into winmo, you can see the Android folder on your SD card and what is inside. You can also see the data.img file, but you can't look inside it and not use anything that is inside.

You can however see the files you copied to

/sdcard/android/root/system/media/audio/notifications/YourAwesomeWhateverNameHere.mp3

and you can use them in winmo.

It's been a while that I used winmo and I can't remember what you have to do to set a audio file of your choosing as a ringtone.

Oh man, it's difficult to explain those things, when english is not your first language.

Let me give you an example.

Let's assume you like listening to Joe Cocker. You have his latest album.

You put that album to your SD card.

When you are in winmo, you start the media player, choose the album and a song and you listen to it.

The same with Android. Start the media player, album, song and listen to it.

If you want to set that song as a ringtone in Android, you have to put it here:

/sdcard/android/root/system/media/audio/notifications/YourAwesomeWhateverNameHere.mp3

and reboot your phone. The song will get copied to the right place and you can use it as a notification ringtone. You cannot choose it as a ringtone when it's not in the right place. But that's a Android thing for ringtones. It doesn't mean you have to put every file there so you can use it in Android.

Android can see everything on your SD card, just like winmo can. One partition.

What a mess. Well, I hope this didn't confuse you even more.

Try to read up on how Android works on the hd2. There are some good faqs that explain things in the sticky threads.
