🚀 Usage

📦 Install using Flatpak

Due to required raw device access (/dev), this app is not accepted on Flathub. For now, install via the file f3-gui.flatpakref

By installing the flatpak package, you won’t need anything else, as everything is already included in it.

Note: f3probe and f3fix require root privileges for direct device access. It will ask for the user’s password when this action is necessary.


1. Plug in the suspicious device
2. Click ↺ Refresh list
3. Select the device
4. Run f3write  → writes test data
5. Run f3read   → verifies integrity (verdict shown automatically)

If the device is fake:
   └─ Run f3probe → detects real capacity (Okay, you can run this one first if you're in a hurry.)
   └─ Run f3fix   → fixes partition table


🔍 Tool overview

Tool Description Root required
f3write Fills device with test files No
f3read Verifies written data No
f3probe Detects real capacity without full write Yes
f3fix Fixes partition table to match real size Yes
