Cannot reformat Sandisk Ultra 32 Gb USB Memory card !!

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
