I purchased my iXpand 3.0 Nov 2017 and only used it twice to transfer from my iPhone 6 to the iXpand. One day it was fine and the next time I plugged it in I could not see my photos/videos. When I plugged it in the 3rd time to move my photos/videos to a 2nd drive for a backup it wasn’t detected, no error messages, I just couldn’t see the drive to find my data. Not on my iPhone, not on my Mac, no on a PC. I read where it says to use the firmware update tool but it asks you to plug in your iXpand but then it doesn’t recognize that I’ve plugged it in. Anyone have any ideas on what’s going on? Please don’t tell me i’ve lost all my precious photos and videos! Thought I’d reach out here before I inquire with SanDisk about how we go about retrieving my data through a service.
