Kingston 8GB class 4 Card not working

[opx20]

I have an Kingston 8GB Class4 SD Card from my Pi but filesystem is broken.
Now im going to insert them in my Windows PC and get error some data could be damaged but after i let him correct this the sd card disappear and only the reader is shown.
If i try to reformat it doesnt work because after error correction from Windows i only see my sd card reader but not the card

Any ideas?
