How to Format an SD Card or USB Stick on Linux, Chromebook & Steam Deck

Quick Shortcut: Linux, Chromebooks, and the Steam Deck all have a simple built-in 'Format' button—no command line needed.

On a Chromebook (ChromeOS)

  1. Open the 'Files' app on your Chromebook.
  2. Right-click (two-finger tap) your SD card or USB drive on the left sidebar.
  3. Click 'Format device', select 'FAT32' (for Sat Navs, Cars & Trail Cams) or 'exFAT' (for large video files), and click 'Erase and Format'.

On Ubuntu / Linux Mint (GNOME Disks)

  1. Open your applications menu and search for 'Disks'.
  2. Click your SD card or USB stick on the left, click the three dots (or gear icon), and choose 'Format Partition'.
  3. Select 'Compatible with all systems and devices (FAT)' and click 'Next' -> 'Format'.

On a Valve Steam Deck

  1. Insert your microSD card into the slot on the bottom edge of the Steam Deck.
  2. Press the physical 'STEAM' button -> go to 'Settings' -> 'System'.
  3. Scroll down and click 'Format SD Card' (this automatically sets it up for Steam games).
