Intenta lo siguiente:

-   Start > Run > type ‘regedit’ (without the speachmarks) > Enter
-   Single-click on ‘My Computer’ > File > Export > save it to the Desktop (Always best to have a backup!!)
-   Go to the following:[/COLOR]
My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDeviceP olicies

*There seems to be some spaces here in 'StorageDevicePolicies' in the text above, there shouldn't be, OK*

-   Double click on the string ‘WriteProtect’ and change the ‘Value Data’ box to ‘0’
-   Then: File > Export > save somewhere useful as something like ‘StorageDevicePolicies001.reg’
-   You also need to do this for the strings in any folders called ‘ControlSet***’ (* = any Digit, i.e. 001, 002) – for example: Everything is the same, just change ‘CurrentControlSet’ to ‘ControlSet***’
My Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StorageDevicePolic ies

*There seems to be some spaces here in 'StorageDevicePolicies' in the text above, there shouldn't be, OK*

-   Save these to the same place as before as ‘StorageDevicePolicies00*’
