I bought a 32GB Ixpand (the smaller thin one) and it initially worked on my iphone 6s and my wife’s. We put hundreds of important pictures on it and then used the app to delete those pictures off the iphones. A few weeks later (and still today) everytime I try to plug it into the iphone 6s it gives a message “Ixpand would like to communicate with the sandisk ixpand flash drive” so I select “Allow”, and then the app opens up and gives an error message “Failed to connect to ixpand drive. Please remove and reattach.” I do that, remove and reattach but nothing is ever detected.
It also does not show up on my macbook or other PC’s that I’ve tried. So now I have hundreds of important photos that have been deleted off our iphones and I am not able to access them on the flash drive. HELP!
