How can I install and run Steam games on external drive? Because I tried to format the drive in ExFAT, NTFS and btrfs (the same of my machine) but with a filesystem I can install the game but it doesn’t start at all, and with another I can’t add the drive as other location on steam

    • I’m on Arch (btw) and the output of lsbk says

      N.B. sda1 is the external drive.

      • I’m not in reach of a pc to test, but I think the problem is that the partition is mounted temporary. Try making a new mountpoint and adding it to fstab (with noauto iirc, so that your system does not hang when you start with the drive unplugged).

          • Create a dir in a place you like

            mkdir (If it is in a dir where you have no write access, you need to sudo or doas)

            Unmount the automounted /dev/sda1

            umount /dev/sda1

            Then mount sda1 to the newly created dir

            mount /dev/sda1

            Then you can use genfstab to create a fstab entry. (You maybe need to sudo pacman -S arch-install-scripts)

            genfstab /

            This will write a fstab file to stdout (the terminal). Look for the line with , copy it and sudo open the /etc/fstab file with your prefered editor. Add the line at tge bottom and add the flags rw,user,noauto to the entry.

            This way you have to manually mount sda1 every time you boot with mount /dev/sda1

            You can add that to your .bashrc or equivalent. (If you don’t plan to remove the disk, you can skip the noauto and the drive will be loaded automatically, but if it is unplugged your system won’t boot normally). Maybe there is a better way, but this way works for me good enough.

  • Mhhh as btrfs it should work. The only thing I noticed is the you have to stop steam connect your drive and restart steam for it to work properly

    My iscsi drive needs a bit to connect so I start steam 30 seconds later after login.

  • Make sure the file system is ext4 and make sure the drive is mounted when you go to add the library on the external drive. A lot of games won’t launch on Linux if the file system isn’t ext4

  • Format it as ext4, set auto flag on fstab and after restart you can select it as secondary library on Steam.

    Not sure about the part if you need to select it from Steam again after you reconnect it though.
