I know this post is kinda old, but I can help. The answer is in the partition tool of Wii Scrubber. Simply load the iso in Wii Scrubber. Right click on the data partition. Under Unencrypted Partition, select extract. Create an empty folder with a name you will remember to extract the files to...
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
