如何从只读文件系统中删除/编辑文件

  • 772

我的存储设备有问题（实际上是一个存储卡，可以像 pendrive 这样的外部存储设备）。

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

我试图更改系统的文件权限，但不起作用

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 的权限-docs-html.zip'：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

    它以只读方式安装；您无法更改权限，您只能尝试sudo mount -o remount,rw /media/A88F-8788. 但如果你的运气和我一样，你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小心地将其放入。

    检查挂载事件/var/log/messages或/var/log/syslog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坏）。

  2. 或者，如果您没有 Windows，请使用以下命令修复 Ubuntu 下的文件系统：

    sudo fsck.msdos -aw /dev/sdb1

    为我工作。

  3. 要求 Windows 修复设备上的文件系统并正确弹出。

  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）找出USB随身碟目录df -Th

    umount2）通过命令卸载U盘

    3）然后，运行dosfsck命令检查和修复文件系统

    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回系统。现在，您的 USB 笔式驱动器应该是可写的。
