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.

Basically follow the first 3 steps, then move your games manually into the newly created Steam\steamapps\common folder. The next time you try to install one of the games, Steam will find the already installed game.
