Script to Auto-Mount NTFS, BTRFS & exFat SDCards, External USB Drives (or SSD Docks) & Internal Partitions (If you Dual-Boot) on the Steam Deck
NTFS & BTRFS Partitions containing a SteamLibrary at root level or in a folder named SteamLibrary
will automatically be added to Steam, exFAT isn't supported as a SteamLibrary but will be Mounted for use with other Launchers or for Media/ROMs etc.

This script is basically a mirror of Valves own Auto-Mount script (which lives on SteamOS at /usr/lib/hwsupport/steamos-automount.sh
) adding in support for ntfs
, btrfs
& exFAT
and adding rules for Internal Partitions.
Additional RegEx has been added to the rules to allow he mounting of "Full Disk" Formatted drives (eg ones that don't have a partitions table) so even drives that are eg sda
or mmcblk0
as well as sda1
or mmcblk0p1
can be mounted.
SteamOS's rule for this lives at /usr/lib/udev/rules.d/99-steamos-automount.rules
and because SteamOS has a Read-Only File System, files in /usr/
cannot be changed without removing the Read-Onlyness, however systemd rules can be overwritten due to how systemd prioritieses directories, so by adding a rule with the same name in /etc/udev/rules.d/
we can override the rule without making changes to SteamOS.
Looking for the old code? see https://github.com/scawp/Steam-Deck.Mount-External-Drive/tree/pre-3.5
a udev
rule is added to /etc/udev/rules.d/99-steamos-automount.rules
which takes priority over /usr/lib/udev/rules.d/99-steamos-automount.rules
this then calls systemd /etc/systemd/system/external-drive-mount@[sda|sda1|sda2|sdd1|etc].service
that then runs /home/deck/.local/share/scawp/SDMED/automount.sh
to Auto Mount any supported SD/External USB/Internal Partitions.
/etc/fstab
is not required for mounting in this way, (however if a Device has an fstab
entry these scripts will still work)

The Drive(s) will be Auto-Mounted to /run/media/deck/[LABEL]
eg /run/media/deck/External-ssd/
if the Device has no label
then the Devices UUID
will be used eg /run/media/deck/a12332-12bf-a33ab-eef/
In Konsole type curl -sSL https://raw.githubusercontent.com/scawp/Steam-Deck.Mount-External-Drive/main/curl_install.sh | bash
a sudo
password is required (run passwd
if required first)
sudo rm /etc/udev/rules.d/99-steamos-automount.rules
sudo rm /etc/systemd/system/[email protected]
sudo rm -r /home/deck/.local/share/scawp/SDMED
sudo udevadm control --reload
sudo systemctl daemon-reload
This will probably have bugs, so beware! log bugs under issues!
