We are currently using sandisk 1GB Compact flash and CF to IDE adapter. In addition to EWF we wanted to have phyically write protect switch for the compact flash to avoid corruption due to power failure. Both the compact flash and CF to IDE adapter doesn't have any write protect switch?.Can any tell me how to do this? or is there compact flash is available with write protect switch?. or is it possible to add the write protect switch in the CF to IDE adapter?.
