我用 8GB 的 USB 2.0 闪存驱动器执行此操作。我正在执行的操作如下：打开 GParted：
然后我尝试创建新分区，但出现以下消息：
之后，我将转到设备/创建分区表并单击 Aply：
然后我再次尝试创建新分区，但出现相同的错误：
这是 GParted 控制台日志：

我也尝试过：
(parted) print
Error: /dev/sdb: unrecognised disk label
(parted) mklabel
(parted) mklabel msdos
(parted) rescue
Start? 0
End? 976773168 // This was just a random guess.
Information: A ntfs primary partition was found at 32.3kB -> 500GB. Do you want to add it to the partition table?
Yes/No/Cancel? yes
(parted) quit
Information: You may need to update /etc/fstab.
但救援后我得到了这个：
radibg2@radibg2:~$ sudo parted /dev/sdb
GNU Parted 2.3
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print
Error: /dev/sdb: unrecognised disk label
(parted) mklabel
New disk label type? msdos
(parted) mklabel msdos
(parted) rescue
Error: /dev/sdb: unrecognised disk label
(parted)
还尝试了低级格式化：
dd if=/dev/zero of=/dev/sdb bs=1M
和上述一切一样，但一切又都一样。
答案1
gparted 的问题可能有不同的原因。这里将讨论其中两种：
- 驱动器包含令人困惑的数据
- 驱动器可能出现故障
令人困惑的数据
有时分区分区表的内容或某些附加信息会造成混淆，例如驱动器已用于 RAID 或用作由混合 ISO 文件制作的启动驱动器。在某些情况下，某些版本的 gparted 会拒绝创建新的分区表和新的文件系统。
然后就可以擦除这些令人困惑的信息了。大多数情况下，只需擦除第一个兆字节 (mibibyte)，用零覆盖即可。可以使用 来完成dd，但这dd是一种危险的工具。韓國'系上安全带' dd，帮你更安全地完成任务。
请参阅此链接：help.ubuntu.com/community/mkusb
清除后，您可以再次使用 gparted。创建分区表，然后您可以创建带有文件系统的分区。
驱动器可能出现故障
如果 mkusb 无法解决问题，则驱动器可能出现故障。它通常以驱动器出现故障的症状开始只读（不仅是文件系统分区，还有驱动器本身）。USB 闪存盘和存储卡可能会发生这种情况，这是故障过程的第一阶段。有时也被称为“死锁”。
但问题可能还有其他原因，因此在放弃之前值得尝试一些方法。
当 U 盘或存储卡为只读状态时
- 在某些 U 盘和许多存储卡上，有一个用于写保护的小型机械开关，可以在读/写和只读之间切换。——您可能无意中将其设置为只读。
- 重新启动计算机并再次尝试使用 mkusb 擦除第一个兆字节。
- 断开其他 USB 设备。有时 USB 设备会相互干扰功能。
- 尝试其他 USB 端口和另一台计算机。
- 在另一台计算机上尝试另一个操作系统（Windows、MacOS）。
- 如果仍然无法擦除驱动器的第一个兆字节，并且驱动器是只读的，则它处于“僵局”状态，下一阶段它将完全“变砖”。

答案2
Gparted 的顶部栏上有一个名为“设备”的选项卡，它有一个名为“创建分区表”的选项，或者你可以尝试使用任何其他分区工具，“磁盘”随 ubuntu 14.04 一起安装
答案3
我会尝试使用老版本的 fdisk，看看它能否创建分区。我还会使用 dmesg 来查看是否有任何磁盘 IO 错误出现，表明可能无法写入。
这个磁盘是什么？它是普通的 USB 闪存驱动器还是某种特殊的东西？
答案4
使用以下方式创建主分区
ext4文件系统- 右键单击未分配的 USB（/dev/sdb）并选择第一个选项新的（ 插入 ）
选择文件系统输入
ext4并点击Add。参见下图。
现在使用磁盘信息面板上方的绿色右侧图标完成此待处理的操作。
笔记：有时你可能会得到一个错误，但不要惊慌，拔下并重新插入，首先
unmountUSB/dev/sdb使用上下文菜单/dev/sdb并重复步骤 1格式化为
fat32完成上述操作后，再次右键单击/dev/sdb并选择格式化为 >并选择
fat32（如果您也需要在 Windows 上使用此 USB）申请完成此操作。
现在你的 USB 已经格式化并具有读写权限
要确认这一点：从导航到 USB 位置地点并右键单击打开的 USB，你可以看到创建新文件夹和创建新文档选项现已激活。
我希望这可以帮助你。
