擦除可移动磁盘上的所有数据

If you have a removable disk, like a USB memory stick or an external hard disk, you may sometimes wish to completely remove all of its files and folders. You can do this by formatting the disk — this deletes all of the files on the disk and leaves it empty.

格式化可移动磁盘

  1. Open Disks from the Desktop.

  2. Select the disk you want to wipe from the list of storage devices on the left.

    一定要确保您选择正确的磁盘！如果您选错了，将会删除其他磁盘上的文件！

  3. In the toolbar underneath the Volumes section, click the menu button. Then click Format Partition….

  4. In the window that pops up, choose a file system Type for the disk.

    If you use the disk on Windows and Mac OS computers in addition to Linux computers, choose FAT. If you only use it on Windows, NTFS may be a better option. A brief description of the file system type will be presented as a label.

  5. Give the disk a name and click Next to continue and show a confirmation window. Check the details carefully, and click Format to wipe the disk.

  6. Once the formatting has finished, click the eject icon to safely remove the disk. It should now be blank and ready to use again.

格式化并不能安全地删除您的文件

格式化磁盘并不是擦除所有数据的绝对完全方式。经过格式化的磁盘不会显示含有文件，但通过特殊的数据软件却可能重新恢复这些文件。如果您需要安全地删除文件，您将需要使用命令行程序，如 shred。
