Deleted SD Card Videos, Then Recorded 56GB More: Is Recovery Still Possible?
Yes, some footage may still survive, but do not expect a paid license to restore video data that has already been overwritten. In this r/datarecovery case, a 128GB SD card was reused for about 56GB of new video after older .ts footage was accidentally deleted. Disk Drill reported about 36,000 video results that would not preview, while DMDE found no useful videos. In a later update, PhotoRec recovered about 18,000 playable files, but the video was heavily spliced and out of order. That means some stream data survived, but it does not mean the original clips remain intact.
Stop Writing to the Card
Do not record anything else to the SD card. If the card is stable, create a byte-to-byte image before more experiments and work from the image instead.
Should You Pay for Disk Drill?
Not just because it lists thousands of videos. Disk Drill itself recommends previewing files before purchase and warns that a file that cannot be fully previewed may be fragmented, overwritten, or otherwise incomplete. Paying can unlock recovery of scan results, but it cannot replace video bytes that new recordings have already overwritten. Treat the 36,000 results as recovery candidates or fragments, not as 36,000 intact original clips. See Disk Drill's scan-result guidance.
What Does the Playable but Spliced PhotoRec Result Mean?
It is actually useful evidence: some deleted video data is still present. But PhotoRec is a signature-based carver, and its own documentation notes that camera video can be fragmented across a memory card. Once deleted file-location information is gone and new recordings have overwritten some of those fragments, a recovery tool may return playable pieces without being able to reconstruct the original clip boundaries or sequence. PhotoRec's video-recovery documentation describes this fragmentation problem directly.
Would a Professional Recovery Shop Do Better?
Possibly for reconstructing surviving video fragments, but not for recovering sectors that were overwritten by the 56GB of new recordings. Because the card is readable, this is primarily a logical and video-reconstruction problem, not a dead-card NAND problem. If the missing footage matters enough, look for a specialist that specifically handles fragmented camera or transport-stream video and tell them exactly how much new data was written after deletion.
Best Next Decision
- You only want whatever is still playable: preserve the PhotoRec results, image the card, and stop writing to the source.
- You need the original clips reconstructed: do not buy another general scanner first. Ask a video-recovery specialist whether the surviving
.tsfragments can be reassembled. - A specific clip was overwritten: neither paid software nor a lab can recreate the missing overwritten bytes.
