Hello Unraid Community. This is my first post here and I found a solution for a problem I had all day and I wanted to share because I was unable to find this exact problem listed with a solution provided. It is entirely possible that I have posted this in the wrong place, mods please feel free to put this where it belongs if so.
The Problem:
Loading Unraid on a 64GB (and presumably larger) thumb drive.
The Solution:
1. Run Unraid USB Flash Creator.
This works as an initial install or as a restore from a backup .zip
2. When it hangs at ‘Syncing File System…’
3. Run Rufus and use following settings:
Boot Selection = FreeDOS
Volume Label = UNRAID
File System = Large FAT32
4. START (Run Ruufus) > OK.
Unraid Flash Creator should finish extracting/installing.
Eject USB
Install in Unraid device.
Incidentally, if the problem (which I saw a few threads on) is that the Unraid Flash Creator is hung up on 'Syncing File Systems', the alternative to Rufus is to run a Windows Quick Format naming the volume 'UNRAID'. When it completes, the Unraid Flash Creator continues its process of building the flash stick.
Thank you all for being such a helpful group.
