When I turn off my car, the HDD will continue to spin for 12-14 seconds and that doesn't seem to be enough for the computer to shut down, so it freezes in the middle of shut down/hibernate.
I checked the voltage, and when the car is off, the HDD only gets 10.5v on the 12v rail and the 5v has 4.95v. when the car is on, they 12v rail gets 11.95v, so that's good. any suggestions?
should i add a sealed 12v battery inline somewhere?
