Why is this repo archived?

I bought some real sd cards and they work fine without ext4. Once again the solution is to throw money at the problem.

The project this is forked from also got archived, so there's no way or reason to keep up with the changes to SteamOS.

Check out their new project: SteamOS BTRFS

fatdeck

Enables vfat (fat32) and exfat file systems on the steam deck.

Features

Format sd cards as exfat

• Automatically given label "SDeck"

Automatically picks up sd cards already formatted to exfat or fat32 (good if you use the official microsd card formatter on a pc)

Have not tested fat32 since nobody should be using it anyways.

This script may or may not get updated as the steam deck gets updated. Should work regardless. Hopefully this hack becomes obsolete.

I straight up copied the btrfdeck downloader, but it should work regardless. Also not tested.

Guide:

1. Download this project to your home directory of the deck.

You'll want to be in konsole, sshd or some other terminal.

    cd ~
    git clone https://github.com/LeifMessinger/fatdeck
    cd fatdeck

2. Setup deck user with a password so that you can run things that need sudo.

passwd deck

3. run the fatdeck_post_update.sh script

If you want to know what it does, read the code.

You may need to give the script execute permissions, so do chmod u+x fatdeck_post_update.sh

To run, you have to do ./fatdeck_post_update.sh

This is because linux will search the default path for an executible unless the command looks like a path. ./ means current directory, but you could just as well do /home/deck/Documents/fatdeck/fatdeck_post_update.sh to run the script.

Troubleshooting

At this point it should automatically mount the drive because both files were changed. If it does not here is how I would troubleshoot:

• Try ejecting the microSD card and reinserting. (Sometimes it'll take a few seconds to mount a large drive.)
• Restart Steam.
• Go to the desktop and check if it is mounted.
• If that doesn't work, try to format in the SteamUI again. I need to figure out where this logs to so I can add that here.
• You could try formatting manually, either through KDE Partition Manager or though the terminal.
• Lastly, if all else fails, you can follow the Undo the changes section below to make it as if you never made a change.

After a SteamOS update

Don't remove password and run the exfat_post_update.sh script by right-clicking it and selecting "Run in Konsole".

Undo the changes:

1. Setup deck user with a password.

passwd deck

2. Change the filesystem to read-write.

sudo steamos-readonly disable

3. restore from the backup.

sudo rm /usr/lib/hwsupport/sdcard-mount.sh && sudo rm /usr/lib/hwsupport/format-sdcard.sh
cp ./backup/sdcard-mount.sh /usr/lib/hwsupport/sdcard-mount.sh
cp ./backup/format-sdcard.sh /usr/lib/hwsupport/format-sdcard.sh

4. Change the filesystem back to read-only.

sudo steamos-readonly enable

5. Remove the password from the deck user.

sudo passwd -d deck
