I think I'm gonna still try to get a working Wii to do a NAND backup.
I've told you not to do that.
This is what you need to do. Format your usb hard drive to FAT32. You can use modmii to download FAT32, or even just run the USB Loader setup wizard (different from the normal wizard on the current version).
NTFS sucks horribly. Even if all you have is ISO files then Wii Backup Manager (which also can be downloaded through modmii) can convert all your ISO's to a FAT32 capable format while removing all the garbage data from the ISO so you save even more space for even more games.
So yeah, use FAT32 and wiiflow.
No matter what, converting a NAND will still result in the same issues with the hard drive.
