Old Scandisk 2GB SD card that I removed from my TT 720 has write protection installed by TT. How can I remove it? So far, I have inserted it back into the TT, deleted all the files and reformatted as a FAT32 file through Explorer while it was loaded in the TT. Then I inserted it into my card reader and I cannot use it, nor format it using Explorer as it is still write protected. Can you give me any advice?
