Hey there fellas
I had a hard drive failure a while back which had my console's initial nand backup on it (firm 3.0.2), made with hekate as soon as I did the RCM exploit (there was a secondary backup, but I have zero idea where I put it as this was 2018). I sent the hard drive to seagate and they sent me back a little hard drive with all of my data on it, but some portions of data were not recoverable and are just empty files that somehow take up space anyway. The nand backup is there, but I want to make sure it is usable.
My question: is there a way to check the integrity of a switch nand backup? My purpose for doing so is to establish sysnand and emunand on my switch.
Before anyone asks, the console still only has 4 fuses burned and game cartridge slot has never been updated.
