SD card write protection

I bought a SD 2 GB
When I want to put photos inside windows will show "card write-protected";

How to remove this protection?

I tried, impossible with my knowledge. If I go further in the system, I see my two drives C and D are FTNS, and the map is FAT it is stated that it is read-only.

Can someone help me...?

Just Check that micro SD card-lock switch (just like the old floppy disks) with symbolized on the map mini padlock open / closed for his position.

Thank you for responding.
I actually found this micro inter. It is set up, according to the arrow's position "lock" is down.

Now it's working properly.
