Tried it. Does not work. It does show up and I can even play games that are on it.
Thanks. I will try that then as a last option, but I really wish there's something else I could try first. I would need to find a place to put all the games I have on it now and there's no guarantee it won't happen again.
EDIT: just realized, you said reconfig it in xbox. My disk is actually not configured for Xbox. It's just a regular Fat32 disk. It used to work like that before. And if I configured it for Xbox, it could only be a small partition as well, not the entire disk, right?
