Hi guys I need some help. Just received my surface rt and got it set up and running. When I went ahead and popped in my microsdxc 64gb sandisk card I got a notification with the three standard options, I pressed do nothing. When I went inside my computer I could not see the sd card. So I popped the sd card into a usb reader and hooked that up to the surface and it worked fine. I can see the card. Ive been trying with two different micro sd cards in the slot and now I don't get a notification when it goes in nor does it show up. I did a fresh reinstall of the surface rt and that doesn't work either. I talked to a support guy and he had didn't have anything helpful to say other than it seems like iam going to have to send it back in the mail, than after they receive it wait 3-5 days to get another one. Yeah I don't wana do that and wait a few weeks to get a new one. Any ideas? My last option is to go to a near by pop up store and try and exchange it.....
