修复写保护（只读）文件系统

我制作了可启动的 USB 驱动器，然后 USB 驱动器被写保护。我使用了以下命令

hrirks@hrirks-MS-7592:~$ sudo fdisk -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes

Partition table entries are not in disk order

Disk /dev/sdb doesn't contain a valid partition table

我尝试了以下命令 磁盘显示

在此处输入图片描述

现在 Gparted 没有显示该设备，但我可以在 Unity 磁盘管理器中看到驱动器，我现在应该怎么做才能修复这些错误？
