    Have you tried to remove the write protection like this:

    1. Plunge the drive or memory card to a computer. (Of course, you should use a card Reader to connect your memory card.)

    2. Click “Start” on the taskbar to open “Run” and type in “regedit”.

    3. Hit “HKEY_LOCAL_MACHINE” to expand “System”.

    4. Find “Current Control Set” in “System” list to click “Control”.

    5. Check whether there is a key named “Storage Device Policies” to change the digit in the “DWORD value” box into “0″ and press “OK”.

    But, if you cannot find the key named “Storage Device Policies”, you are supposed to create a one: right click “Control” to create a new key and name it as “Storage Device Policies”=> right click this new key to highlight “DWORD Value” and name it as “write protect”=> Double click this “write protect” box to change the number.

    i created the key and set it to 0 but it still didnt work still says sd card write protected cant post a screen shot but is this ok this is where the key is:

    computer/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Storage Device Policies

    in storage device policies there are 2 items:

    (default) REG_SZ (value not set)

    Write Protect REG_DWORD 0x00000000 (0)
