I'm pretty sure there are tools for recovering corrupted data on usbs and sd cards. I'm not sure what this does exactly, but there are times where the computer asks you to make it scan your device. I think it scans for any potential viruses, but again, I don't know. It could be looking for broken files and such. Another thing you could do is put it on a virtual storage like google drives, which gives you 15GB worth of space, which should be plenty for a story, though depending on how big it is, you could possibly go over 15GB it's not impossible, just unlikely from what I've seen.
