Quick Fix to SD card not recognized GS4 for Windows users.
Okay so if your sprint galaxy S4 gives an error that "SD card removed" "insert sd card" then I have a quick fix for you.
This fix will only work if you have Microsoft Windows XP and above.
Open up a file explorer.
plug in your SD card and make sure that the computer recognizes it.
If SD card is not recognized then unplug and try checking if it is recognizable on any Linux Distrobution.
If the card is recognizable:
Right Click the SD card and then click properties
Then go to tools and click Check Now under Error Checking
Click run when the dialogue apears and wait
When complete, eject the SD card from the system tray and then plug into your device. It will temporarily fix the problem. It worked for my phone and it may work for yours. If you have any issues related to this problem try this and see if it helps. Used to have to use this whenever our hard drives would fail during a class project. This Error Checking Does Not Have to find any errors. As long as it says it is completed this should work.
