Hi, I have just bought my first SLR a Canon EOS 1000D. I have a Silicon Power 16GB HC Class 6 High Speed SD Card. Having taken my first pictures, I inserted the card in my laptop and the Media Manager opened with an option to transfer files. There was an option to delete the image files upon transfer, which is what I did. Now, however, when I put my SD card in the camera it says it is write protected. I have tried accessing the SD card, and have enabled sharing, but I cannot find an option to release a write protection on my computer. Anyone any ideas? By the way, this is my first post, and as a newbie I would like to say thank you to all you helpful souls out there. Much appreciated.
