如何从只读文件系统删除/编辑文件

我的存储设备（实际上是充当像 pendrive 一样的外部存储设备的存储卡）出现了问题。

experimentx@workmateX:/var/www/zendtest$ sudo rm /media/A88F-8788/python-2.7.1-docs-html.zip
rm：无法删除“/media/A88F-8788/python-2.7.1-docs-html.zip”：只读文件系统

我尝试更改系统的文件权限，但没有效果

experimentx@workmateX:/var/www/zendtest$ sudo chmod 0777 /media/A88F-8788/python-2.7.1-docs-html.zip
chmod：更改“/media/A88F-8788/python-2.7.1-docs-html.zip”的权限：只读文件系统

但它在 Windows 上完美运行。

更新

打开驱动器并运行命令sudo mount -o remount,rw /media/A88F-8788

答案1

它以只读方式安装；您无法更改权限，只能尝试sudo mount -o remount,rw /media/A88F-8788。但如果您的运气和我一样，您在插入卡时设法抓住了卡上的“锁定”滑块，并且必须将其弹出并更加小心地放入。

检查/var/log/messages挂载/var/log/syslog事件或可能的文件系统损坏（这可能导致内核以只读方式重新挂载它以避免造成更多损害）。

答案2

或者如果你没有 Windows，请使用以下命令修复 Ubuntu 下的文件系统：

sudo fsck.msdos -aw /dev/sdb1

对我有用。

答案3

要求 Windows 修复设备上的文件系统并正确弹出它。

答案4

这篇文章很有帮助：http://sharadchhetri.com/2013/12/19/how-to-fix-read-only-usb-pen-drive-in-ubuntu/

1）通过以下方式找到 USB 驱动器目录df -Th

umount2）通过命令卸载USB驱动器

3）然后，运行dosfsck命令检查并修复文件系统

4) 之后，您可以从系统中移除 USB 笔式驱动器并将其重新连接到系统。现在，您的 USB 笔式驱动器应该是可写入的。
