问题始于 Windows，驱动器名称打印出乱码和奇怪的字符，并且一些文件和文件夹自动创建了相同的乱码。通过 Windows 格式化并尝试不同类型的修复指南都没有帮助，主要是因为它被写保护了。
启动 Ubuntu 尝试修复此问题，正常格式化会导致错误消息
Error wiping device: Command-line `wipefs -a "/dev/sdb1"' exited with non-zero exit status 1: wipefs: error: /dev/sdb1: probing initialization failed: Read-only file system
(udisks-error-quark, 0)
尝试使用 gparted，但卸载驱动器会导致此错误
Unable to open /dev/sdb read-write (Read-only file system). /dev/sdb has been opened read-only.
Unable to open /dev/sdb read-write (Read-only file system). /dev/sdb has been opened read-only.
Unable to open /dev/sdb read-write (Read-only file system). /dev/sdb has been opened read-only.
(gpartedbin:6382): glibmm-CRITICAL **:

尝试更改读写权限但似乎没有效果
sudo hdparm -r0 /dev/sdb
/dev/sdb:
setting readonly to 0 (off)
readonly = 0 (off)
gparted 相同的输出和
sudo mkfs -t vfat /dev/sdb1
mkfs.fat 3.0.27 (2014-11-12)
mkfs.vfat: unable to open /dev/sdb1: Read-only file system
sudo mkfs -t vfat /dev/sdb
mkfs.fat 3.0.27 (2014-11-12)
mkfs.vfat: unable to open /dev/sdb: Read-only file system
chmod 也不起作用
find /dev/sdb -type d -execdir chmod 777 -Rv {} +
find /dev/sdb1 -type d -execdir chmod 777 -Rv {} +
fdisk -l 输出

答案1
您已将驱动器安装为只读 - chmod 将不起作用，因为它是一项写入操作。
您需要重新安装具有读写权限的驱动器：
sudo mount -o remount, rw `/dev/sdb1`
替换sdb为您的设备名称。
