To uninstall Tails from a USB stick, and use it for something else, you have to reset it.

The content of the USB stick will be lost in the operation, but an attacker might still be able to tell that Tails was installed on that USB stick using data recovery techniques unless you securely clean all the available disk space afterwards.

以下的操作指示不適用於 Windows XP
Windows XP 版本下的Diskpart沒有列出可移除裝置清單。

    A new disk, which corresponds to that USB stick, appears in the list.

       Disk 1    Online         8 GB      0 B
    

    Make sure that its size corresponds to the size of the USB stick that you want to reset. Note down the disk number assigned by Diskpart to the USB stick.

  6. To select the USB stick, execute the following command: select disk=number. Replace number by the disk number of the USB stick that you want to reset.
