As was said before, This is a problem for a mobile scanner
VEHICLE INSTALLATION You can mount your scanner in your vehicle, using either an optoinal bracket or DIN-E sleeve. If the scanner loses power (as when you turn off your car’s ignition with the scanners power switch on), it can corrupt the microSD card. To ensure that does not happen, turn off the scanner before turning the car’s ignition off.
While I am not an electronic engineer or a software engineer, it seems this was overlooked. This is a problem that has been talked about with the 536 and seems to not have been addressed with the SDS200. That is very disappointing to me. There are several other things I wish were included in the new flagship but not deal breakers, but the power issue makes me, personally, not an early adopter.
I might be wrong, but I HIGHLY doubt this can be resolved by firmware as hardware would need to be changed or have the ability on the board already but not enabled to force the scanner to power down without corrupting the sd card when power is removed.
