我有一个处于只读模式的 USB：
getfacl: Removing leading '/' from absolute path names
file: media/user/USB/
owner: user
group: user user::rwx group::r-x other::r-x
运行时fsck -p /dev/sdc1，我收到：
fsck from util-linux 2.37.2 /dev/sdc1 is mounted.
WARNING!!! The filesystem is mounted. If you continue you
***WILL*** cause ***SEVERE*** filesystem damage.
Do you really want to continue<n>? yes fsck.ext2: Permission denied
while trying to open /dev/sdc1 You must have r/w access to the
filesystem or be root
sudo fsck -p /dev/sdc1或者sudo dosfsck /dev/sdc1：
*** Filesystem was changed *** The changes have not yet been written, you can still choose to leave the filesystem unmodified: 1) Write
changes 2) Leave filesystem unchanged [12?q]? 1 /dev/sdc1: 5 files,

permitted Writing 512 bytes at 0 failed: Operation not permitted

sudo fdisk /dev/sdc1：

sudo rm filename.mkv：

sudo chown user:user /media/user/USB/：

挂载/卸载无关紧要，我无法更改或修改 USB，尝试过sudo -i，sudo su没有帮助。我在网上查看了所有指南，但上述命令之一帮助那个人解决了问题，但对我没用。USB 没有可见的只读模式，以前从未发生过这种情况。
我也尝试删除它的条目，sudo nano /etc/fstab但没有帮助。
