Tutorial [Q] I think there's something wrong with my phone's file structure

I've had a terrible time trying to flash a rom recently. Long story short, I suspect that 'wipe data' is actually wiping my SD card (in addition to, or instead of the internal memory). I have no idea if this is truly the case or how I would fix it if it was. Can someone look at the attached image and tell me if it looks ok or if there's something else I can use to diagnose my issue? I lost my TI backup!
