I have a Verizon Turbo Droid 2 running Android 6.0. Recently, for some reason, my 64 GB external micro-SD card unmounted, and I have been unable to remount it. Most of the data stored is recoverable from other sources, but, some is not. I've tried removing the card and reinserting it, and also tried to read it directly from my PC (Windows 10). If I connect the phone using a USB cable, I can see the internal storage from my PC, but, not the micro-SD card. I have also inserted another card, and the phone sees it just fine. I've looked on the net for info concerning programs for reading Android micro-SD cards, but everything I've found assumes you wish to read the card while mounted in the phone/tablet. Any information I find on mounting the card manually starts with "Format the card". Does anyone have any suggestions about mechanisms for reading the card directly from my PC, remounting the card, or recovering data from the card? Thanks.
