exception handling around GetDrives()? #261

Open bobeaton opened 3 years ago

bobeaton commented 3 years ago

Some of the users of Chorus in OSE get the below exception stack (green screen of death). I think in the past it was when maybe they had something plugged into a USB port... Is it possible to add exception catching if GetDrives() fails?
