Hedge's ParaShoot integration will tell ParaShoot when a Source is ready to be erased and ejected after a successful transfer. ParaShoot always asks for confirmation.
If you Parashoot-ed a card by mistake, you can restore the card by re-inserting it into the reader and choose the Restore option from the ParaShoot menu.
Once ParaShoot is installed, enable the ParaShoot integration in Preferences.
Enabling this integration disables Auto-Eject in Hedge.
