There are a lot of SD cards with fake capacities, they appear to be large but are actually a smaller card reprogrammed to do so. You only find out when you go beyond the true capacity. There are tools to check this, such as sys-block/f3. Yes, I tested the card in the dashcam, it has been running reliably for several years, including producing footage that the police used in their prosecution of a drunk driver. I've also used a microSDXC card in a camera, with an SD adaptor, with no issues. =20 > Oh - and 32GB cards are physically different from 128GB cards because=20 > they work to different standards. They are, but the differences are minor so don't necessarily cause compatibility issues. However, it is always worth making sure than the card and camera are fully compatible before trusting it to anything important. --=20 Neil Bothwick Evolution stops when stupidity is no longer fatal! --Sig_/tqJ9VoSaEDJqcbI=GrzmKse Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE8k9T/rX16EJxEKG692eFu0QSMJgFAl7xBNkACgkQ92eFu0QS MJjVEBAAr8AFoCkyo7T/v9aSDUXd/pHBKNMI6YewGofyIGTYhVUdBpXIsMRhRJBv y0uC68cYuxEfBMZ1JZmNs5L6Pzc4SCXpdMIv9a7nbo831EFWQgzZrcOmge91xN2I VImXENywaayWkievk1LEuwXHusy9AYoq+y3u5AHdMc12hXiauvgG1wZs9Rpt5AmZ +Z+04FJGDKpzQZhJONFBOfpo3FTmIqL9G79VWMsmcyEge9ZpsCakrdlkXBDY/XzB isDnMcfipzQ+qKBfrHBsjfH+0JuAOwxS/BQSpIHOHGmSs2Lk22KGgHd3HKlKyw8/ ehNatbWAU4NwcLrpaal4i0RPGDRmc3/4SZEXTEoCSYSxLWK6PcYB8isigPpCOp1u fBcskEiAPnf2UYqdH0vgPqM9gDhF5XtFPYL7b2tn/+Pb9JbYA31xO6qlfSrPUjGH E2Z2eAUrphzvDElcfH13tg0HT1SXrOvXBpnH+7Pysb6BjWlTNm2iZN+r7qI7CGIz 7tXSTPx7DYTuiypq4G6zx57l4gcguIZWj//TwdbDa6TJngh8RR+VFMIuqlqZeP/9 50Mob0zv9Cg86sm7Ipy73HTn2ZCsuq88X6QIK2m+PrF9Bx+pwVDWevU7VvzBgawg elAxeBrKPDGr9PDWS8K50fNkoE5/se3s2w31gK4pnKzRxxdCcCA= =92B9 -----END PGP SIGNATURE----- --Sig_/tqJ9VoSaEDJqcbI=GrzmKse--
