you cannot access Device files and folders while connected as Disk Drive mode, only storage card.

This is kind of a funky error if you say AS syncs just fine.

I would plug it in, wait till the green wheel stops spinning then close the sync thing so it's just in your taskbar.

then open windows explorer and click on "mobile device" and see if it opens (even after a lag).

Also, which OS are u using?
