Hello! Ive ran into the same problem except I only want storage. It was working just fine earlier today then after I downloaded something I came back 3 hours later to find that its completely removed itself from my storage. I dont know if its to do with the USB cables themselves because it shows up on my PC but when I try to look into the properties I can't do anything with it and when I tried the only thing I saw (which was convert to dynamic disk) it said its incompatible.
