Windows surface RT Micro SD card issue.
Tried installing my 32gb micro sd inside of my Windows Surface RT. However, when I placed the chip inside and formatted it, it only comes out to show "15.9 MB free of 15.9MB".
Surface RT will recognize 32GB SD card (or larger). Now, you need to delete the existing 16GB partition and start over. Right-Click on Start Menu/Computer Management/Storage/Disk Management. Select the SD card disk and delete the existing 16GB partition. Now, create a new 32GB partition and format it: either NTFS or exFAT (I prefer exFAT). That should work. If you encounter a problem, let me know and I will try to replicate it on my RT.
