For the past 6 months I've used a 32gb micro sdhc card in my nextbase dashcam with no problems at all. I've formatted the card once a week as suggested in the dashcam information booklet and have succesfully used the provided adapter to transfer files on to my windows 10 laptop several times. Yesterday I noticed that the dashcam was saying there was an "sd card error" and since then I have not been able to use it. No matter what device I try (2 different laptops, dashcam and samsung galaxy s8 phone) it's never recognised. Does anyone have any tips? I'm really not good with things like this and have no clue what to do.
