Hi, I've just bought a micro 4gb sdhc card on a store and everytime I plug it in my laptop, it can't be recognize. I also bought the m3 real rumble pack RAM on the website www.kickgaming.com wich gave me an adapter for micro sdhc cards. When I plugged the 4gb sdhc card, into the m3 adapter to the laptop, it just recognize the m3 adapter and NOT the 4gb sdhc card. I tryed to format it but I get a message saying me that "there's no device plugged in." Thank you for your help. EDIT: I currently have the windows SP3.
