I used a Sandisk Ultra 32 Gb USB Memory card in my Camcorder a few days ago without any issue . Yesterday, my cam corder could not read this card anymore so I tried to reformat it on my Windows 10 PC but Windows always said it could not complete the operation .
The strange thing is I could still delete and write in this card on my PC . But when I refresh the screen and click on this Mem card , the deleted videos reappear again as if no deletion occurs at all .
I have tried other third party SD card formatters but nothing works ! Is this brand new SD card a toss now ? Please help
