The problem with Itunes syncing is that it is usually a one way sync. If you uploaded originally from Itunes and it is in your library everything is fine. If you get the media on your device by some other means (or from a different computer using Itunes) and you sync, it will remove said media from your device because it isn't in your library. For fun some time, try syncing your apps. If you downloaded them direct to your device (the normal way I would submit) and you haven't transferred the purchases, this apps will be deleted from your device because they aren't in your library.
ALthough, not game to try it, I would believe that if the apps weren't transferred, then they would be deleted from the IPAD.
But, I have just been through the exercise of getting camera to IPAD images from my IPAD.
The only way I got it to happen was that I had to wait till the IPAD turned up as a device on my PC, only then was I able to do anything.
In this case, I was able to go to the DCIM folder on the IPAD, and transfer the images.
