    I have a 128 MB pendrive that has a write protect by a sliding switch.

    Peter_England I am with you. I miss these pendrives. I wonder why they don't make these types anymore.

    Then those links I posted will take care of that without the physical circuit modifications.. have fun virus hunting

    Thanks for the link I have contacted to seller.but can any one have knowledge how to do it by modifying the circuitry of the PENDRIVE? if that costs high I can make one from my old drive thanks.

    and weird.. when searching for a flash memory IC with a physical hardware write protect pin I came across a post on another board where you asked this same question last year.. funny this is a post about "memory"

    But like they told you before.. If your memory IC or controller IC has a physical write protect pin you typically just pull it low to enable hardware write protection. If it doesn't its gotta be done in software.
