Nope, the specs leave it up to the device to implement, kind of like the old notch on floppies ;-) >From the Nokia n800 user manual: This device does not support the write protection feature of SD cards. I don't believe the write protection switch was part of the original MMC card design specs was it? I'm not "in the loop" but it's only recently I started seeing cards with the switch. I'm assuming it sets some bit somewhere to tell the hardware "Hey, leave me alone" which Maemo promptly ignores.
