I mean, if that's where your usb_install_pc.py is then it did work. But ehh, long as you got it. :D As for your other issue, not sure. My card is ExFAT and I have had no issues loading anything. 6.2 / with the latest Atmosphere.
cd into the folder where usb_install_pc.py is, then:
python3 usb_install_pc.py /where ever the folder is containing your nsp, hit enter.
Note: It can't link directly to the nsp, just the folder the nsp is in.
I finally modeled and 3d printed the new HDD cages I need in order to build my 2nd NAS. Original ones don't fit the mounting holes on the hdds I'm using. Been sitting on this project for over 2 years smfh
Also another 70TB going in the front mount drive bays of this server. 182tb raw, going to probably use a zfs RAID-Z3 for 3 parity disks, so 140TB usable
I could claw back 14tb by only doing 2 parity disks but I feel like with 13 disks in the RAID I'd be kind of pushing my luck on rebuild time if I encounter a disk failure
