After 1.5 hour of recording while mountain biking no video recorded

Hi all,

during my vacation I wanted to explore one part of the island and had my GoPro Hero 7 Black attached to the external power on my chest while mountain biking. After approx. 1.5 hour of riding I got a puncture so had to fix it. At that time I stopped recording while GoPro was still on and did not want to switch off. I unplugged it from external power, tried holding power button for about 5 maybe more seconds but it behaved like being frozen.

My first question: how much longer after recording is stopped the camera yet records to the card? I was recording at 2.7K, 60.


So as it did not want to switch off I pulled out the battery which might have taken me roughly about 20-30 seconds until I got it out from the case on my chest and opened the battery door. Now when trying to download the videos I realized that my 1.5 hour footage is not on the card. I believe as GoPro records 4 GB sets of files there should be at least 5-6 videos even when I interrupted recording by pulling out the battery.


Any explanation what could have happened? Is there any way I could recover those lost videos?

Re: After 1.5 hour of recording while mountain biking no video recorded

I observed a similar symptom and it turned out to be the SD card - it was technically OK and on the 'known to work' list, but obviously still too slow for the recording.


The camera ran really hot, and I was unable to turn it off except for pulling the battery - video was unusable.


I think the write retries caused this. Swap card against a new one (same make), issue gone.
