Has definitely solved the issue of mounting. Managed to mount 4 seperate USB sticks. Perhaps this needs to be passed onto the scripts somehow if its not mounting properly?

Also failed to mount (or recognize) an external harddrive, that isn't a fair test, however, as its first partition is WBFS (for Wii) and not even sure it has an extX or fat partition on it.

Also could you add and option to disable portrait mode? (Or at least note it for much later releases) as I find it particularly annoying when I'm plugging and unplugging things constantly? :P
