如何格式化已损坏的 USB？

我正在尝试格式化用于安装 Ubuntu 的 USB。我试过了，磁盘，出现错误。fdisk这是我得到的结果：

我不知道该怎么办……请帮帮我！我对这一切都很陌生。

还原到标准存储设备

您可以使用 mkusb 将克隆的 USB 启动驱动器恢复到具有 MSDOS 分区表和 FAT32 文件系统的标准存储设备。我认为这就是您所说的格式化。

查看这些链接，

  • 安装 mkusb

    如果您运行标准 Ubuntu Live，则需要额外指令来获取存储库 Universe。（Kubuntu、Lubuntu ... Xubuntu 已自动激活存储库 Universe。）

    sudo add-apt-repository universe  # only for standard Ubuntu

sudo add-apt-repository ppa:mkusb/ppa  # and press Enter
sudo apt-get update
sudo apt-get install mkusb mkusb-nox usb-pack-efi

  • 使用 mkusb 恢复到标准存储设备

    在此处输入图片描述

其他分区表和/或文件系统

如果您需要其他格式、其他分区表和/或具有其他文件系统的分区，请先使用 mkusb 删除可能引起混淆的数据，然后使用 gparted。

  • 在这种情况下，让 韓國 擦除第一个 mibibyte进而

  • 安装分区如果尚未安装

    sudo apt update
sudo apt install gparted

  • 然后使用分区

    • 从下拉菜单开始设备 - 创建分区表进而

    • 使用文件系统创建分区具有直观的用户界面。
