Weird SD Card Reader Issue
 

My laptop (Dell Inspiron 700m) has an SD card reader on the side. Just bought a new camera, and a 2gb SD card. Took some pictures over the fourth, and when I tried to use the card in my laptop, it didn't read. While it usually pops up the options menu when I put in a card, it didn't with this one, and when I'd try to access it through My Computer it would freeze the screen. The card works fine in my desktop's card reader (the desk top is older than my laptop), and my older SD card works fine in the laptop. Any thoughts?
