that you can look over and see if it applies.
I would really encourage you to purchase an SD card reader - it's a drop in the bucket for the amount of headaches that it would likely prevent. I'll also note that I made sure that any micro-SD card that I purchased comes with a full size SDcard adapter that the micro slides into for use in a standard SD card slot.
