Emergency · affected camera card
Why you must stop using an SD card after deletion
Why should I stop taking photos after deleting files?
Short answer
Because deletion only marks the space as free: the photos stay on the card until the camera needs that space again. The next burst or video can land exactly on those blocks. Switch the camera off, remove the card and take no test shot until the card has been scanned read-only.
The situation
The camera still appears usable after important files were deleted.
Deleting a photo in the camera removes its directory entry and releases its clusters; the image data itself is still on the card and unchanged. The camera has no way of knowing that you want it back, so it will happily allocate exactly those clusters next.
01 / Diagnose
Work out what actually disappeared
The risk is proportional to what you shoot next. A single frame writes a few megabytes; a burst or a video clip writes continuously and fills free space in large runs, which is why one short clip can end the chances for dozens of deleted photos. Windows offers no recycle bin on removable media, so there is no second layer to fall back on.
Deletion marks space reusable; the next burst or video may replace the exact blocks needed for recovery.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Switch the camera off rather than just closing the playback screen, because some bodies keep writing management files while they stay powered.
- 2
Open the door, take the card out and put it somewhere you will not pick it up again by habit, ideally labelled.
- 3
If the shoot has to continue, use a different card; do not free space on this one by deleting anything else.
- 4
Read the card in a computer through a card reader and scan it read-only before it goes back into any camera.
The test shot is the classic mistake: one frame to check that the camera is fine, taken straight into the free space the deleted photos occupy. Formatting the card to tidy it up before recovery has the same effect and adds a new directory on top.
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.
Stopping early keeps the door open; it is not itself a recovery, and it cannot help photos that a burst already overwrote before you noticed. File Recovery Hero can read the card and show what is still there without writing to it.
04 / Verify
Check the recovered content, not just its name
The measure of success here is negative: the card should show the same used space and the same number of visible files as at the moment of the deletion. A later scan that still lists the deleted filenames with their original sizes confirms the entries survived.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can affected camera card be recovered in this situation?+
Deleting a photo in the camera removes its directory entry and releases its clusters; the image data itself is still on the card and unchanged. The camera has no way of knowing that you want it back, so it will happily allocate exactly those clusters next. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
The test shot is the classic mistake: one frame to check that the camera is fine, taken straight into the free space the deleted photos occupy.
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?+
The measure of success here is negative: the card should show the same used space and the same number of visible files as at the moment of the deletion.
