Maybe that useing a notebook hard drive or ssd drive could help.
In any case a hdd which not using the 12v source, uses less amps consumption and is fast enough for recording/playing.

Other test could be,
Disconnect the hdd, use a usb stick or external hdd station for recording and playback.
In any case one that is fast enough for recording and replaying.
