Recover deleted videos from an exFAT microSDXC card
How do I recover videos from a microSD card?
Short answer
Take the card out of the action camera or drone first, because the device can reuse deleted space with its very next recording. Then put the microSD into a stable reader, avoiding adapters that drop the connection, scan it read-only for MP4 or MOV and play each recovered clip completely.
The situation
Action-camera, drone, or compact-camera MP4 or MOV files are missing.
Action cameras and drones are the fastest overwriters there are: they start a new recording within seconds of powering up and write continuously at high bitrate. The card has to leave the device before anything else, and the clip format decides how it is judged afterwards.
01 / Diagnose
Work out what actually disappeared
MP4 and MOV keep their index, the moov area, together with the media data, and many devices write it only when the recording stops properly. A flat battery or a crash therefore leaves a large file the player refuses to open. Deleted clips are a different case: the data usually sits in one long run that a read-only scan can follow.
Small removable media behaves like other flash storage: new recording can reuse deleted extents immediately.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Power the action camera or drone down and eject the microSD card; leaving it in means the next flight or ride writes over the clips.
- 2
Use a reader that holds the card firmly, avoiding the flimsy adapters that disconnect mid-read and turn a long clip into a fragment.
- 3
Scan the card read-only for MP4 and MOV only, so the result is a list of clips instead of thousands of unrelated fragments.
- 4
Export every candidate to a computer disk and play each one through, including the chapters that the device split at the 4 GB boundary.
Do not put the card back to check whether the device can still see the clips, and do not let the manufacturer's app format or repair the card. A single short recording is enough to cut a deleted clip in half.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
A clip whose moov area was never written cannot be made playable by recovery alone; that needs a repair tool, run on a copy. File Recovery Hero reads the card and returns clips as they are, without repairing damaged containers.
04 / Verify
Check the recovered content, not just its name
A clip is only good if it plays to its final second at full resolution, with the frame rate the device recorded and sound where sound was recorded. Skip to the end first: a truncated file often starts perfectly and stops at the point where the data runs out.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can exFAT microSDXC card be recovered in this situation?+
Action cameras and drones are the fastest overwriters there are: they start a new recording within seconds of powering up and write continuously at high bitrate. The card has to leave the device before anything else, and the clip format decides how it is judged afterwards. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not put the card back to check whether the device can still see the clips, and do not let the manufacturer's app format or repair the card.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
A clip is only good if it plays to its final second at full resolution, with the frame rate the device recorded and sound where sound was recorded.
