I think that is the point RR_NDB wants to bring forward :
If the recorders have their own independent power supply, they will keep recording.
My point of logic was: if you have no power for instruments and sensors there is absolutely nothing to record.

Sure, you can verify that any specific data was missing, but if the data cannot be generated or transferred, it cannot be recorded. If you loose all power on a modern aircraft there is nothing left to record if you do not create a completely independent array of sensors powered equally independently
