    Hello,

    Inside the microSD flash memory, and SD flash memory, there is a bit, that
    once programmed, the data inside the chip becomes write-protected, and
    permanent. I searched for a tool that can program this bit, but I did not
    find any. Do you know of such a tool? Or driver? Or Software? Any
    thought on this will help me. Thank you very much.

    Best Regards,
    T.I.

    You might want to post that question over in the comp.arch.embedded
    group -- that bunch there is always playing with stuff like that at the
    bit level. Another group to try is the sci.electronics.design group.
    Or, you could just put tape over the pins .... oh, you wanted to still
    be able to read from it :)

    'sdlock' for Linux.

    Thank you for the suggestion. I searched the web for sdlock, and found
    only an application for an embedded board. Is this the sdlock you are
    referring to?
