如何从只读文件系统中删除/编辑文件

Question

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，但这不起作用

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

但它完美地适用于Windows。

更新

在打开驱动器和运行命令时 sudo mount -o remount,rw /media/A88F-8788

/var/log/syslog：

Answer 1

它以只读方式安装；你不能改变权限，你只能尝试sudo mount -o remount,rw /media/A88F-8788。但是，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小心地放入。

检查/var/log/messages和/var/log/syslog用于安装事件或可能系统文件损坏（这会导致内核重新挂载为只读，以避免造成更大的伤害）。

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。
