Hacking the SD Nav Card - In THEORY

In THEORY, what would happen if you copied all the files from the SD Nav Card to a read/write 16GB SD Nav Card, and then modified some of the .png files to get different icons for things like your home, favorites, etc?

Anyone ever theorized about this?

A new nav card won't work. There's some secure/embedded info on the factory card that allows it to be recognized by the MFT unit. The copied card would not have it, and the unit would treat it just as a data card. It has been tried before on the Edge forum.

But you idea IS certainly cool.

Would that info happen to be the *.key file?

chances are you don't have access to the real secure content. SD manufacturers/developers have that locked tight and it has not been cracked yet. Also I recall reading some cameras utilizing serial/manu codes from the card itself to verify authenticity. Could be possible with MFT too.

How is it that they make the SD card read-only? The little switch does nothing, so is there some attribute on the actual media?

SD (Secure Digital) was widely adopted by media companies because it has some propitiatory technology to hide and lock content from the end user. This has yet to be cracked and probably wont be because it relies on some hardware-level markers.
It's not just a flash memory card.. it can distribute content that is locked, it can run integrated hardware (like the eyefi cards), it can hide storage space (as well as anything saved to it).

All SD readers are subject to the gateway technology of the card that dictates how the card is interpreted when it is plugged in. No way around it as of yet.

If you worked for a memory company you might have tools to clone it, but nothing in the consumer world can.

It's not a matter of the card being read only.

There is a portion of the memory that you cannot access without the proper tools.

SD = Secure Digital

Actually, that's not even possible either.

The way SD cards work is that the memory can be sectioned off completely, and given special attributes. What this means is that someone can set a certain amount of memory as a separate partition that can only be accessed by a specific hardware ID code, and it can *never* be seen except by that piece of hardware.

Not even memory tools would be able to read it. That's the entire reason this format was created. It was made so that media companies (music and movie) could protect their content from ever being read by anything but their own products. It's basically a way to not allow the content to ever be copied, and cracking it would be almost impossible.
