Memory card is damaged , not supported

Hi,

I bought a Sandisk 32gb Micro SDHC card class 10 and using since 18 months .Last night I deleted some pics and video and switch off the phone. Today morning(13/02/18) when I switch on the mobile It shows the card is damaged, please try to format it.
It is not detected by my android phone.So I try to connect it through a USB card adopter to my PC and It opened but when I cut my data and pest on computer the storage capacity shows same.When I try to format it in basic FAT,NTFS or exFAT. Windows prompt message “Windows was unable to complete format”.

Please Help!
Thanks!
