read-only recovery scan: use after formatting
How does read-only recovery scan help after a quick format?
Short answer
Often yes, after a quick format: it rewrites only the file-system management data, while older payload blocks remain until new writes reuse them. A read-only scan searches those areas without adding a single write. It cannot help after an overwrite or full format, so record which option ran and keep the card unused.
The situation
Old folders are gone while the newly formatted source appears ready to use.
A quick format is a bookkeeping operation. It writes fresh management structures and an empty directory, then reports the card as ready, while the recorded data still lies in the area the new directory no longer describes. A read-only scan searches that area instead of trusting the directory.
01 / Diagnose
Work out what actually disappeared
What decides the outcome is which format ran and what happened afterwards. A quick format in camera or in the operating system touches only management data; a full format or a secure erase writes across the whole medium. Every photo taken and every file copied after the format claims free space and can land on the old recordings.
New file-system records and older payload blocks can coexist until later writes reuse them. For read-only recovery scan, this matters because a safe scan keeps the read source and export destination separate
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Take the card out of the camera before anything else and keep it out, because a single test shot can consume the space you need.
- 2
Write down which format option was used, where it was run and how much was written to the card since then.
- 3
Scan the card read-only from a computer, allowing a full pass rather than stopping at the first results that appear.
- 4
Export the candidates to a different drive, keeping folder names the scan proposes so you can tell reconstructed groups apart.
Do not reuse the card for a quick test and do not copy files onto it to see whether it still works. Each write claims free space, and free space after a quick format is exactly where the old recordings still sit, so a single test shot can remove them.
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.
Nothing recovers what a later write has replaced, and a full format or a formatted SSD with TRIM active usually leaves nothing to find. File Recovery Hero reads exFAT, NTFS and FAT16/FAT32 cards only, scanning free of charge and exporting with a licence at 50 €.
04 / Verify
Check the recovered content, not just its name
Results after a format look convincing before they are checked: open the exported photos at full size and play the longest clips to the end. Original filenames often do not return, so match files by capture time, resolution and content rather than by name.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can stable readable exFAT source be recovered in this situation?+
A quick format is a bookkeeping operation. It writes fresh management structures and an empty directory, then reports the card as ready, while the recorded data still lies in the area the new directory no longer describes. A read-only scan searches that area instead of trusting the directory. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not reuse the card for a quick test and do not copy files onto it to see whether it still works.
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?+
Results after a format look convincing before they are checked: open the exported photos at full size and play the longest clips to the end.
