Recovering corrupted photos, video and audio
Can corrupted media files be recovered or repaired?
Short answer
Sometimes, but in two separate steps: recovery finds the best surviving source bytes, and repair then fixes container or header information on a copy. Neither step can invent overwritten video, photo or audio content. Keep the original file and a card image untouched, and check the repaired output from start to finish.
The situation
A file exists but will not open, has the wrong duration or stops partway through.
A file exists but will not open, has the wrong duration or stops partway through. If the original source has not been written to again, useful file-system traces or data blocks may still remain for media file or recording card. A read-only scan can assess the source, but no result should be promised before that examination.
01 / Diagnose
Work out what actually disappeared
Recovery locates the best available source bytes. Repair then fixes container or header information on a copy. Neither step can invent overwritten content. For media file or recording card, first separate a missing path, folder or volume name from actual deletion. That distinction determines the safest next recovery step.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Disconnect or remove media file or recording card and prevent further writes.
- 2
Write down the device, the date and the last action before the loss so you can match recovered files later.
- 3
Check known destinations, backups and trash without restoring anything onto the source.
- 4
Export every candidate only to internal storage or a physically different drive.
Preserve the original file and card image, then validate the entire repaired output. Do not record a test file and do not approve formatting or file-system repair.
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.
Software cannot reconstruct overwritten blocks or storage cells that are no longer readable. If the source disconnects repeatedly or becomes unusually warm, a professional laboratory is the safer route.
04 / Verify
Check the recovered content, not just its name
Validate files recovered from media file or recording card completely: compare the size and format, then read the content from beginning to end. A preview or surviving filename is not proof of a complete recovery.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can media file or recording card be recovered in this situation?+
A file exists but will not open, has the wrong duration or stops partway through. If the original source has not been written to again, useful file-system traces or data blocks may still remain for media file or recording card. A read-only scan can assess the source, but no result should be promised before that examination. The result still depends on what remains readable on the source.
How do I know whether the result is complete?+
Validate files recovered from media file or recording card completely: compare the size and format, then read the content from beginning to end.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
