I have a Toshiba Satellite Pro A200 01H, PSAE4C which has a newly installed windows 7 ultimate 32 bit, i am missing a driver in my device manager under mass storage controller, my sd card isn't working so i'm presuming that is why. Can anybody direct me to this driver? I can't seem to find anything on the toshiba website for this particular laptop model. I've tried windows updates and done google searches but haven't had any luck yet!
