CHKDSK Moved GoPro Clips Into FOUND.000: Can the Videos Be Recovered?
TL;DR:
Stop using the GoPro SD card immediately and do not run CHKDSK again, as your original photo and MP4 video data may still be recoverable from the generated FOUND.000 folder and .CHK files.
● Create a verified byte-level copy of the stable SD card to work from and preserve the FOUND.000 folder separately without deleting or blindly renaming the CHK fragments.
● Export selected clips to a separate healthy disk and play their entire duration to verify integrity, because recovered MP4s might remain fragmented or unplayable despite displaying correct filenames or previews.
● Readable SD cards can be evaluated with Recoverit Memory Card Recovery, keeping in mind that no scanning software can guarantee the restoration of missing portions from damaged clips.

If a GoPro SD card shows FOUND.000 and .CHK files after Windows Scan and Fix, do not run CHKDSK again. The repair may have changed directory links, but some original photo or video data may still be recoverable from the card or an image.
In this r/datarecovery GoPro CHK-file report, a crash and unsafe removal preceded Windows repair. The poster created an image, compared tools, and reported that most files were recovered while some MP4 results remained unplayable.
Preserve the Remaining Evidence
Keep the original card out of use and make a verified byte-level copy if it remains stable and one does not already exist. Preserve the FOUND.000 folder separately too; CHK fragments should not be deleted or blindly renamed in place.
Microsoft explains that CHKDSK can save lost allocation chains as .CHK files. That process is not the same as restoring original names, paths, and full video sequences.
Test Recovered Footage, Not Just File Counts
Work from a stable image or separate copy and compare available file-system reconstruction and signature recovery results. Original filenames or correct-looking previews are useful clues, but an MP4 may still be fragmented or incomplete.
Export selected clips to a separate healthy disk, open and play their full duration, and compare them with the camera originals or backups if any survive. A readable card can also be evaluated using Recoverit Memory Card Recovery, but no scan can guarantee the missing portions of damaged clips.
