  • Consistent SD Corruption

    Posted by lukec on 2025-06-20 at 23:03

    This is most frustrating, I’m burning through SD cards at a rate of knots with this to the point I wish I never purchased it now.

    I’ve purchased the recommended cards in a variety of makes and capacities and finding that they corrupt sometimes within days, sometimes within weeks or months depending on how big the capacity is for the card.

    Anyone else had this issue? I’ve worked through all the trouble shooting, checked the adaptor is fitted security to prevent moisture ingress etc etc etc but at the point of ripping the lot out.

    I’ve recently put in a SanDisk MaxEndurance 64GB MicroSDxc U3 class10 card which lasted all of 2 weeks before the rapid flashing red light comes on the unit

    Prior to that I used a SanDisk 128gb Extreme MicroSDxc U3 A2 which lasted 3 months before corrupting. Prior to this I had a SanDisk MaxEndurance MicroSDxc 128gb which lasted a year and also been through a few Lexar versions of the same all amounting to a year and a 9 months of use and a total of 6 memory cards.

    The camera unit is connected via a thunderbox which provides some power for a few seconds after turning the bike off. I’ve checked all connections, and they are all as they should be

    Hi Luke,
    What setting did you use for ‘Loop Recording’?
    And how do you format the SD cards?

    How did you connect the yellow wire? Did you also connect the red and black wires to the Thunderbox? These are also switched by the Thunderbox?

      Hi Hans, thanks for your reply. I’m keen to get this sorted as it’s become annoying and unnecessarily expensive to have it now.

      Loop Recording is set to continuous overwrite. I format the SD cards from within the app but I’ve also tried formatting via my windows PC to FAT format too.

      I don’t have a yellow wire in my K6 dash cam (it was one of the first production ones ordered the moment they released in the UK, not sure if that makes a difference). I have a white wire as an extra but don’t use that as per the manual.

      Red and black wires are connected to the relevant ports on the thunderbox and the thunderbox manages the power to the K6. Hope that helps

      Power to the unit seems good, but I get the rapid red flashing light whenever one card breaks.

    Hi Luke,

    It is recommended to only format the SD cards using the Innovv app. An SD card formatted with a computer can sometimes cause problems. Innovv cameras sometimes cannot handle an SD card formatted by a computer.

    I suspect that the white wire is the same as the yellow wire. So the switch wire. You should use this. If the K6 is switched off suddenly because the voltage on the red and black wires drops, this will certainly cause problems. The current recording cannot be closed properly and the SD card can also become corrupted.

      Forgive me I just went and checked – the Yellow wire is there, it’s connected into the port as the Red wire terminals on my thunderbox

      I’ve formatted one Lexar card using the PC as I wanted to try it bearing in mind every other time I format is via the Innov app

    Hi Luke,
    I think I see the source of the problem.
    You have the yellow wire connected to the red wire. And that is a ‘no-go’ and the ultimate recipe for problems.
    The red and black wires should be connected to a constant plus and minus. The yellow wire should be connected to a switched power supply.

      I thought the thunderbox is designed to effectively a bit switched connector hence the set up… Can I put the yellow wire into another one of the green/black thunderbox terminals then? Or do I have to feed it somewhere else entirely?

      Btw I appreciate your help with this
