I have two exact the same 16GB SanDisk 45MB/s Class 10 for over 2 years now, I’ve been using them with my Nikon D5100. One of the two SD cards won’t show up in Windows Explorer since a few weeks. I’m running Windows 8.1 64-bit and I’m using the built-in SD card reader on my ASUS N550JK
Funny thing is, the other SD card still shows up like they both normally did. The malfunctioning SD card still works and I can still access my photos through another PC. Also, connecting the Nikon with my PC with the SD card inside my camera allow me to access the pictures.
Does anyone know how to solve this? I want it to show up in my Windows Explorer like it did a few weeks ago.
Thanks in advance.
