Disabling / Suppressing SD(HC) Write Protect

Question

I know that the write protect tab in SD cards is not a real hardware protection, but a simple signal to the reader that the card is write protected. For example, the CHDK project for Canon cameras specifically ignores it, and once had a cheap flash reader ($2 by mail from Hong Kong) which didn't recognize it.

Is there any way (registry hack, custom driver, anything) on Windows to prevent this flag from being set? I'd like my SDHC reader to also ignore the write protect tab; has anyone ever heard / seen such a thing before?

Answer 1

I'm not sure about any registry but the controller MUST support such feature (or lack of feature ^_^) from a driver point of view, I doubt this is standardized.

Good luck

Answer 2

did you ever figure out a solution to this. i have CHDK as well and I assume you, like I, always forget to change the lock switch everytime you go from camera to computer, and i'm getting tired of forgetting. is there a way to edit the driver or a registry hack that can force windows to ignore write protection switches?
