I'm making a SD Card data logger.
I'm using an Arduino Uno Rev3 with Adafruit Datalogger shield.
The user can remove the SD card and insert it into their computer to copy the file.
Does anyone know anyway that I can protect the file on the SD Card?
I want to be able to write to SD Card when in the datalogger but not allow the user to edit and save the file when the SD card is in a windows PC.
I've used some commercial dataloggers and I don't know how they work but when you plug them into a PC you can edit the files on them but as soon and you unplug and plug them back in all the files are reverted to their un-edited form.
Does anyone know how I can do something similar with Arduino?
