  7. Hi,

    My microSD card also 64 gb became unrecognizable by my phone as well, plus windows 10 won’t let me format it. I had a microsd card adapter so was able to put it in my camera (Nikon) and the camera software automatically saw that it wasn’t formatted so I said yes to the formatting request. Worked when I put it back into my phone. I have also been able to get my card working again with EaseUS partitioning master pro software but the camera trick worked fine. Since then I have switched to the fastest microSD card I could get.

  31. How to prevent SD card data from formatting after making it as internal storage.

  32. I just purchased a new unlocked samsung galaxy s5 SM G900v. It came with Android version 6.0.1. When I insert a mmc card that has been formatted on my computer, it says unsupported SD card. I only have a portable storage option. When I select the SD card a menu pops up that says to use this SD card it must be set up. I push set up and a format menu pops up, I press format, it formats 20% then a menu pops up that says command 8 volume partition failed. This card works fine in other devices. I have wiped it clean and formatted it on my computer. I have tried several different cards with the same result. HELP! I would have NEVER purchased this phone without being able to use an mmc card for additional storage. I have another samsung galaxy s5 with lollipop and have no issues with the mmc card.
