Well just a word to the wise not all sdram card adapters are created equal. I’ve just removed my TF card from the dashcam to review its footage…. Linux scanned and rejected the card as corrupt beyond repair… Windows came back with read errors throughout the initial sectors… Try a different adapter as I have a few… Hey presto OK not perfect but easily corrected error and files retreved…
Moral of the storey keep adapters from all cards as some seem to read better than others.
