Hi, I currently have a 16 gb class 2 micro SD card in my D1. I also have a 16 gb class 4 micro SD card in my possesion, completely empty (I think). So I ould like to know: 1: How can I run liek a diagnostics on a card, to find out stuff that was supposed to be deleted, and more info about it. 2: What is the best way for me to copy all of my stuff from one card to the other, then totally erase the other card. 3: Drive forensics? I think that will answer my 1st question, but what is it and how cna I get it? I have Windows XP, Mac OSX leopard, a D1 P.S. Are kingston 32 gb micro SD cards good quality?
