Need to check it by yourself. Try both combinations. In Samsung Utility, should be a picture with correct PIN placement.

Nothing will happend. If you will connect terminal wrongly - SSD will not detect terminal.

Firmware update with _FORMAT option will allow to erase all user data and restore SA to default settings.
