GoPro high-bitrate video fails during copy
Why will one large GoPro clip not copy?
Short answer
Usually the destination or an unreadable card area: a target without enough free space or large-file support stops the copy, while a failure at exactly the same point every time suggests the clip crosses a bad region. Check the destination first; if it is fine, image the card instead of retrying the copy.
The situation
Short clips copy, but a large chapter fails at a repeatable point.
Small clips copying while one large chapter fails points at the destination or at a specific region of the card, not at the file itself. A failure that happens at the same byte position on every attempt is the clearest signal that the copy is hitting an unreadable area.
01 / Diagnose
Work out what actually disappeared
There are three plausible explanations. The destination may lack free space for a multi-gigabyte chapter, or be formatted FAT32, which cannot hold a file of 4 GB or more. The card may have a weak region the reader retries until the copy times out. Less often, the reader or cable drops the connection under sustained load.
The file may cross an unreadable region or the destination may lack capacity or large-file support.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Check the destination first: confirm it has far more free space than the clip and is formatted exFAT or NTFS rather than FAT32.
- 2
Try one different reader and a direct port rather than a hub, then attempt the copy once more and note where it stops.
- 3
If it fails at the same point again, stop copying and create a full sector image of the card as an unencrypted IMG or DD file.
- 4
Recover the chapter from that image rather than from the card, and copy the remaining clips off before the card is used again.
Do not retry the same copy a dozen times; every retry stresses the region that is already struggling. Do not run a repair or check utility on the card, do not reformat it to make the copy work, and do not carry on filming with it.
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.
If the card has genuinely bad blocks, imaging will skip them and the chapter comes back with a damaged section that no software restores. File Recovery Hero reads supported volumes and unencrypted images without writing to them, but hardware faults belong with a recovery lab.
04 / Verify
Check the recovered content, not just its name
A successful copy is one where the file size on the destination matches the size on the card exactly and the clip plays to its full duration. Pay attention to the region where the copy used to fail: if the picture breaks up there, the data was read incompletely.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can GoPro card and destination drive be recovered in this situation?+
Small clips copying while one large chapter fails points at the destination or at a specific region of the card, not at the file itself. A failure that happens at the same byte position on every attempt is the clearest signal that the copy is hitting an unreadable area. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not retry the same copy a dozen times; every retry stresses the region that is already struggling.
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?+
A successful copy is one where the file size on the destination matches the size on the card exactly and the clip plays to its full duration.
