I have a Kioxia 64GB micro SD card that I got with my dash cam. It was working fine for a few months, recording as expected and overwriting old files. However, it's now stopped working properly; the recordings only last about 10 seconds and don't always show up on my computer. Some of the .mp4 files won't open in VLC or QuickTime, and I've noticed weird dates on some files which makes me suspect they might be corrupted. To troubleshoot, I bought a new SanDisk micro SD card, and the dash cam works perfectly with it. So I know it's not the camera. I'm wondering if there's any way to fix the original card or if it's just a lost cause. I'd hate to throw it away since it seems to be in good condition physically. Can anyone explain what might have gone wrong and if there are any options to salvage it? I'm not very tech-savvy, so please keep it simple, thanks!

It's highly likely that your micro SD card is beyond repair. When a card starts going read-only, that usually means it's reaching the end of its life. If it can’t write any new data, there's not much you can do. Sometimes these cards fail without any visible harm, so you're not alone. It's unfortunate, but the safest and most reliable option is to let it go and keep using your new card for peace of mind.
Unfortunately, it sounds like your micro SD card has succumbed to what’s called bit rot, which can happen when cards are constantly written to, like in a dash cam scenario. It’s not uncommon for these cards to fail, and when they start acting up, it’s usually a sign they’re on their last leg. Honestly, at this point, buying a new card is probably your best bet since you can't really trust the old one anymore. It’s best not to rely on cards that show issues like this.
Yeah, dash cams can be pretty tough on memory cards because they write and erase data a lot. They can get overheated as well, which doesn’t help. If your new card is working without any issues, it sounds like a smart move!
Thanks for the insight! I guess I was hoping there was some way to save it. My camera was really abusing the card, then!
I was hoping it could be fixed too, but I understand now. It’s a bummer, but not the end of the world. Thanks for clarifying!
