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!
