Hacking Nand Problem

[Blastoise]

Ok so I have a few different nand files on my computer cause Iv hacked a few friends wiis aswell and backed up their NAND onto my computer.
Problem, I just realised I cant tell which one is mine... -_- yeah stupid of me

Is there a way if I can tell which NAND is mine
OR
Is it possible for me to still backup my NAND even though my Wii is already hacked? Or is there something else I can do?

Nothings happened, it just struck me and i just wanna do something about this in case something does happens.

Make another NAND backup now, save it to a new directory on your PC, and then compare the keys of your known Wii, to the Keys of you other Dumps.

One would assume the keys should remain exactly the same.

In fact, just did same, there were 2 bytes different in the middle ??

But the first few hundred bytes are identical, which also houses the unique console ID

Ok so its safe to recover using an NAND that was created after hacking?

 

[C.S.I.]

Sure, but your system will revert to the exact same state as when the NAND backup was made, including any hacks.

Yeah I noticed the different bytes when I've taken multiple NAND backups. I just keep the keys and nand.bin file in a directory that is the consoles nickname and date it was taken. That way if I ever need t restore I have the nand/key pair as they were dumped.
