How can I complete format?

I get "windows was unable to complete the format" error when I try to format my micro sd card on my computer. So I check everywhere in the drive and I find a folder that gives me "the file or directory is corrupted and unreadable" error when I try to delete or access it. I can delete everything else but it reappears after I reinserted the drive. I tried to format with command prompt and I get "invalid media or track 0 bad - disk unusable." I also treid Panasonic SDFormatter but I get "the memory card is write protected please release the write protect switch"
