Does anyone have any clue what's going on here? I'm trying to backup one SSD to a newer SSD in a new PC I'm building. It's just a secondary disc where I install games, doesn't have system files. But it's "Invalid" while it works perfectly fine on my other PC.

Why is windows being so fucking gay about a disc? Asking bing is giving me conflicting replies and some say "convert to basic disk" may incure data loss. I don't want to copy 600gb accross LAN. Fuck this gay earth.
