Problem
A card is formatted in-camera immediately before copying, erasing the only copy of a take that had not yet been archived.
Solution
Root Cause / Diagnostic:
Lack of physical media state tagging and human workflow error led to formatting a camera card before DIT ingest. While standard camera quick-formats wipe only the File Allocation Table and root directory rather than zeroing NAND flash, recording even a few seconds of new footage immediately overwrites unindexed data.
Actionable Fix:
1. Emergency Read-Only Lockdown: Immediately flip the SD write-protect switch or remove the card from the camera; do not record a single additional frame.
2. Raw Carving Data Recovery: Run deep signature-based raw recovery software (such as PhotoRec, Klennet Carver, or Disk Drill) to carve unfragmented video streams directly from raw NAND blocks.
3. Physical Status Tape Workflow: Enforce physical tape tagging: cards with exposed red tape are unbacked media; cards with green tape are verified and cleared for format.
Pro Tip:
Establish a simple physical rule on set: cards stored contacts-down in cases are uncopied footage; only cards stored contacts-up are cleared for formatting.
