I have a SanDisk 64GB dual flash drive I had no problems with it up until recently. I borrowed it to a friend and he somehow screwed it up by creating an unused partition on it and I had to reformat it. Now when I plug the micro side into my phone I get the message “USB Device Removed” even though I am mounting it not removing it.
I have tried reformatting to both exFAT and FAT32 and get the same message with both when connecting it to my phone. I have tried restarting my phone with the drive connected with both exFAT and FAT32 with no luck still. My phone is a Moto G and the flash drive worked perfectly with it before. I am now at a complete loss of what to do next.
