MicroSD card randomly unmounts itself

I inserted a Samsung EVo 128GB micros-SD card into my new Surface 3, intending to use it as photo storage for my photography workflow.

However, after a fee minutes - even without using it - the drive appears to unmounts itself. It's still visible in Explorer, but clicking it results in Explorer hanging and eventually giving the error "please insert a disk" after several minutes. In Disk Manager, the drive sometimes appears, with the correct amount of space, but indicates it's all unallocated.

This issue is fixed temporarily by removing and reinserting the disk, but a short time later it unmounts itself again. I tried the disk in my older Dell Venue 8 Pro, but the issue didn't occur there.

I've looked at previous threads about similar issues on older and Pro models, and tried setting the policy for the microSD drive to 'better performance' and even tried setting up a VHD, but none of these provided a solution.

Does anyone know what I can do?

    nope. I cannot use 128GB cards in my Surface 3. I've seen no indication that

    Microsoft is even looking into the issue.

    In my case a Samsung Evo 128 didn't work but an older Samsung did 128 did. Seems some work and some don't.

    Microsoft apparently has no interest in fixing this issue. My Surface totally failed, wouldn't boot, within 3 months and their customer service was remarkable in that it was the worst I have experienced. So much so, that I will never own another hardware product made by them. Luckily I had purchased it at Costco and returned it and got my money back.

    Good luck.
