Makes sense then, after all 800 is more than 750 ... The leftover space has most likely been taken up by the downloaded packages in /var/cache/pacman/pkg/. I suggest you keep some more space free to have some room for cases like this. If your OS still boots normally, you can just delete part of the cache manually as described in the Arch wiki, no need for peripherals. If it doesn't boot it will be more complicated, in that case I would just flash a fresh image (you could backup files with Jumpdrive before).
