GoPro SD Card Error: Card Problem or Corrupted File?

GoPros report storage trouble in two very different ways, and they call for different responses. SD ERR or NO SD on the screen means the camera can't talk to the card at all. A small file-repair icon after a shoot means the card is working but the last recording didn't close properly. The first is a card problem. The second is a file problem. Mixing them up wastes time, and sometimes footage, so start by working out which one you have.

If the screen says SD ERR or NO SD

Per GoPro's own troubleshooting, this message means the camera can't communicate with the SD card. Work through it in this order:

1. Reseat the card. Power off, eject, and push the card fully back in. A card that isn't seated all the way produces exactly this error.
2. Copy your footage off with a card reader, then format the card in the camera. Formatting rebuilds the filesystem and clears most SD ERR cases, but it erases everything, so the copy comes first.
3. Test the card's speed. Record one clip at a low resolution and frame rate, then one at a high setting like 5.3K or 4K120. If SD ERR appears only in the demanding modes, the card can't sustain the write speed the camera needs. Replace it with a faster one.
4. Try a card from GoPro's recommended list. Counterfeit and worn-out cards are a common cause here. Buy from a reputable seller.

If several known-good cards all produce SD ERR in the same camera, the fault is the camera's card slot, not the cards.

If you see the file-repair icon

The camera found a recording that wasn't closed properly, usually because the battery died or the card was pulled mid-write. Press any button and the camera attempts an automatic repair; the icon blinks while it works. This built-in repair handles clean truncation and often succeeds, so let it finish.

When it fails, or when the "repaired" file still won't play, you're past what the camera can do. The recording's frames are almost always still in the file. What's missing is the index, the moov atom, that the camera never got to write. That's a container rebuild, which is what our engine does. The GoPro Hero 12 truncated file guide covers this failure in depth.

Card failure or file corruption? A quick triage

• Card mounts in a computer reader and files are listed with realistic sizes, but a clip won't play. File corruption. Repairable. Skip to the upload below.
• Card won't mount anywhere, or mounts empty or garbled. Card or filesystem failure. A free carving tool such as PhotoRec can often pull files off a card whose filesystem is gone. Carved files frequently won't play (no index, or fragments); that output is then a normal repair case.
• A file is listed at 0 bytes. The camera never wrote any data for it. There is nothing in that file to repair.

Why the file broke in the first place

GoPro's high-bitrate modes push cards hard, and a card that falls behind mid-recording gets the take cut short. Batteries die in the cold, housings flood, cameras get knocked off mounts. All of these end the recording before the index is written, the same truncation covered in file truncated, and leave an MP4 that looks normal on the card and opens nowhere.

How our recovery handles GoPro files

• No reference clip needed. Codec parameters are read from the frames in the broken file itself.
• H.264 and HEVC both handled, covering every recent Hero recording mode. Detection is automatic.
• AAC audio is rebuilt alongside the video.
• Chaptered recordings: GoPros split long takes into multiple files, and normally only the final chapter is damaged. Upload just that one; the earlier chapters are fine as they are.
• Files over 4 GB get the 64-bit chunk offsets they require.
• Processing happens on EU servers and files are deleted after 48 hours.

What you do

1. Upload the broken clip.
2. A free 5-second preview arrives about a minute later, picture and sound.
3. Pay only if the preview shows your footage. From $5 per file. Nothing to pay if it doesn't work.

FAQ

Will formatting the card fix SD ERR? Usually, because it rebuilds the filesystem the camera is choking on. It also erases everything on the card, so copy your footage off with a reader first. Format in the camera, not on the computer.

The repair icon ran, but the file still won't play. Now what? The built-in repair only fixes the simplest truncation. When it gives up, the frames are normally still in the file and the container can be rebuilt from the stream. Upload it and judge the preview.

Do I have to buy GoPro's own SD card? No. Any card on GoPro's recommended list works. What matters is a genuine card rated for the sustained write speed of the modes you shoot; counterfeit high-capacity cards behave exactly like a dying real one.

Why do I only get SD ERR in 5.3K or 4K120? Those modes need sustained write speed for the whole take. If low settings record fine and high ones error out, the card can't keep up. Replace it with a faster card from GoPro's recommended list.

My file shows 0 KB on the card. Can you recover it? No. A 0-byte file contains no data at all. If the data was ever written elsewhere on the flash, card-level carving with a tool like PhotoRec is the only avenue.
