I inserted a USB drive before I inserted the SD card and now the USB is D:\ and the SD card is E:\. I gracefully ejected both and shut down the RT. Now the SD card is E:\ even without a USB drive in. How do I get it named back to D:\?
Disk Management under Computer Management (right click on the Computer Icon and click manage), right click on the SD Card and Change Drive Path and follow the prompts...
