I'm trying so hard to do a full NAND backup but it fails everytime.
I'm on 3.0.0 atm and have got two mSDs (FAT32 and exFat).
My FAT32 fails with either a
bad sectors error or with "
Fatal error (1) when writing to SD Card". Always at something around 43 to 46 %.
Also there's no
partial.idx file at all. And everytime I retry (although some files are already present if I insert the card into my PC) it seem to start over again from the very beginning.

My exFat card doesn't even start to dump anything but gives me the "
failed to mount sd card fatfs" error.
Don't have exFat drivers installed in Horizon if this is important. Also I formatted the card to exFat using just the explorer in Windows 10 and without changing any settings. Was that wrong?
I'm really tired as it always takes around 60 minutes to dump (on my FAT32 card) just to end up in an error and I have to start over.
Just want to dump my NAND before I can use the guide to update to 5.1 without burning fuses.
