Now that it's getting colder out, I sometimes run into the "hard disk not found" error, so it would be nice to be able to use my factory head when the empeg is out of the car.

And let me just say that if you're getting that error, something is flat-out wrong and should be fixed.

Whether the "wrong" thing is one of these problems, or it's your desire to leave your fragile hard disks out in the cold, either way, the situation should be corrected.
