I hope this is an OK place to ask a Question about Sd CArd copy protections. I have also posted this in the Flash memory forum
I am trying to copy mapping software for my GPS. I live in a area where 2 map cards cover my area. I want to copy both cards to 1 larger one. The cards will copy, but the copies will not work unless reinstalled on the original SD card. I know this must be some sort of CPRM protection, and I have read on this forum that it can be defeated. I cant even make a working backup of my softwares. The cards are Lowrance Fishing Hot Spots Maps. The documentation says to make a B/U, but when I called to ask how the rep said only a B/U for the original card (a lot of good that does if something happens to my cards or GPS unit).
Anyway, If someone would give me some help it would be greatly appreciated
