Default USB Mass Storage Woes

I'm a Mac guy, and since I got this phone a little more than a week ago, I've been plagued by the fact that I can't mount the SD card on my Macbook. I always get a notification that the drive isn't recognized. However, the virtual cd with the Windows drivers mounts, but not the SD. Does anyone know of a mod that will only mount the SD card, and completely ignore the virtual CD? Better yet, is there a way to completely delete the virtual Cd function? Thanks!
