if you refer to the "Lock" switch of SD memory cards, then please note that this "Lock" switch is only evaluated in OS software and no physical/electrical protection of the flash IC. Normally, the mechanic "Lock" switch only pushes away a contact on the SD card socket, so the OS can evaluate whether the contacts are conncted or not. On GNU/Linux I think it is sufficient to just mount -o remount,rw a previously read-only mounted SD card. USB sticks with real physical (i.e. electrically routed to the write-protect pin of the flash IC) write protection are rare, but they exist (as you said). _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
