Fix a GoPro SD card error before recording again
Protect existing footage, verify the exact camera card requirement, test insertion and free space, format in-camera, and replace a failing card.
Direct answer
The shortest reliable path.
Stop recording attempts and copy readable footage off the card first. With the GoPro powered off, remove and reinsert the card, then confirm it meets the exact camera model’s capacity and sustained-speed requirements. After backup, format the card in the camera. If SD ERR, repair messages, or recording stops return on a recommended card after a camera update, replace the card rather than repeatedly formatting valuable footage.

Scope before steps.
GoPro HERO cameras that show NO SD, SD ERR, FORMAT SD, file-repair messages, full-card warnings, or unexplained recording stops.
Data recovery guarantees, physically broken slots, counterfeit-card authentication, overheating-only shutdowns, or non-GoPro cameras.
Procedure
Do this in order.
- 01
Preserve the readable files
Stop recording and copy the card through a reader when the files remain accessible; verify several copied clips.
- 02
Classify the camera message
Distinguish no card, full card, unreadable format, file repair, and temperature warning before choosing a fix.
- 03
Verify the exact card requirement
Match the GoPro model to its documented capacity and speed class; current HERO12 and HERO13 guidance calls for V30 or UHS-3 or higher.
- 04
Reseat, then format in camera
With power off, inspect and reinsert the dry card. After backup, use Preferences → Reset → Format SD Card on supported models.
- 05
Run a controlled recording test
Update the camera, then record a demanding mode long enough to exceed the previous failure point while monitoring temperature separately.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| Camera reports FULL | Back up media, verify the copies, then delete or format. | The camera can read the card but lacks free recording space. |
| Computer reads card; GoPro shows SD ERR | Verify model support and format in the camera after backup. | The card may have an unsupported or damaged file system for this camera. |
| Error returns after in-camera format | Test a recommended known-good card. | The original card is suspect even if it still mounts on a computer. |
| Temperature icon appears instead | Stop and cool the camera before testing lower-load settings. | The recording stop is thermal, not proven to be a storage fault. |
Stop conditions
Know when not to keep changing things.
- Do not format or continue writing when unbacked-up footage is still needed.
- Do not remove the card while the camera is powered or writing.
- Replace the card or contact GoPro when errors persist across a documented recommended card, current firmware, and in-camera format.
