Please describe your issue in as much detail as possible:

When I add a drive via fstab to a mount point (ex: /mnt/slow-storage) the drive appears to be attached but shows the wrong amount of storage available. A drive auto-mounted at media seems to show correctly though.

In my example, the mounted drive is a 4tb HDD given the name "slow-storage" it appears that the drive isn't showing the correct amount of free storage and is instead showing the same storage that the system has available.

Steps for reproducing this issue:

1. Mount a drive to /mnt/ using fstab
2. Add the drive to Steam (in my example, /mnt/slow-storage/steamlibrary)
3. Note the available storage being inaccurate
