Hi. Not sure if this is the right place to post--let me know. I have a new HP Laptop17t 300 Envy Notebook Product #8YK40AV. It comes with what HP calls an "SD memory reader." I regularly use a Sony Handy Cam that uses the Memory Stick Pro Duo. The HP's slot is too large. My question is: what type adaptor can I use . (Pro duo is smaller than a regular SD card). I have searched high and low for an adapter but no luck. Any help appreciated.
