SD Card Write protect problem!
I plugged in a SDCard(SanDisk 4GB) with the write protect On in my Ubuntu system. Ideally this shouldn't have allowed me to write to this card. But it did. And that's when I found that it was getting mounted as a rw filesystem instead of ro. But the same card when I inserted it in another Ubuntu system with write protect On,this problem was not there. So nothing wrong with the Card. Guys...Some help needed on this please!
