Dashcam Footage Deleted or Overwritten? How Loop Recording Works and What's Still Recoverable
Dashcams record in fixed segments and delete the oldest unlocked clip when the card fills — but 'deleted' comes before 'overwritten,' and the MP4 data survives until new footage physically reuses that space. The guide covers the three failure modes (loop overwrite, card corruption, manual deletion), why the card must come out of the camera immediately, computer-side carving of MP4/TS segments, partial clips at the overwrite boundary, and evidence-handling for insurance disputes.
