Windows suddenly doesn't recognize micro sd

My Windows can't recognize my 8 gb micro sd, even though it can read it fine before. It works fine in my device and on my brother's computer, but I just can't seem to get it working on my windows. If I insert the micro sd card into my laptop card reader, it says I need to format it, but I'm not sure I should do that. The only difference I can see is that it reads micro sd card as drive I: when it usually reads it at H: I tried plugging off my other devices and restarted and then put it back on but it still stays at I:

Just to make it clear, I could read the micro sd just fine before today
