How to remove write protected memory card. I have a problem with a card reader A-data 52 in 1 and

Question

I have a problem with a card reader A-data 52 in 1 and the RS-DV-MMC for my 6630. When I try to transfer files on it an error message apears : Cannot copy: The disk is write protected. Remove the write protection or use another card... I tried to format the card from the phone... no result - the same problem. I tried to format it from the card reader but it's write-protected and windows doesn't allow me to do that. Just help me :) There's no use of that card reader if I can only copy files from my cellphone. Please help me...
