My machine has a single NVMe slot, so I swapped my 500GB drive with a 2TB last night and did a fresh Bazzite install. I put the 500 into a USB enclosure and hooked it up expecting to be able to copy my games off of it. Steam sees the old drive but lists all its contents as “Non-Steam”.
I have tried ‘repairing’ the library but that does nothing. I tried manually mounting the drive to another path but with the same result.
What’s the best way to get the games off this drive?
Edit: just to clarify, the 500GB drive is a Bazzite install. It was the primary drive until recently.


I’d mount it as a second storage location in Steam, then, within Steam, use the storage option to move the files over to the main library. That will ensure that they all get moved properly and reduce any potential issues.
