is my 2gb sandisk micro sd still repairable?

I could delete files and put files in the mem card but i cant format it. I tried the sd formatter it says write protected but my sd reader is on unlock, not only that after i deleted all my files i took it out of the reader and when i put them back in the files returned! so if u think about it i cudnt really delete files or put files in the mem card. when i try the windows format it says unable to comlete the format and tried formatting it to fat 32 ex fat etc. now the question is "is there anything i cud do to make my micro sd work perfect again?"
