我有一张 16GB 的微型 SD 卡，它通过 Lexar microSD RDR (0815) 适配器使用。我可以在 Windows 上读取和写入它，但在 VMware 中我只能编辑现有文件。我无法删除任何文件，也无法拖放或创建新文件。
我运行了 dmesg | tail 命令，输出如下：
dmesg | tail

我运行了 fsck，结果如下。
fsck.ext4: Permission denied while trying to open /dev/sda1
You must have r/w access to the filesystem or be root
swgroup@fwdev2-smount:~/Desktop$
swgroup@fwdev2-smount:~/Desktop$ sudo fsck
[sudo] password for swgroup:
fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
/dev/sda1 is mounted.
e2fsck: Cannot continue, aborting.
我应该怎么办？
谢谢！
答案1
首先是unmount驱动器。低级磁盘实用程序（如fsck）会更改物理磁盘，这可能不再与 存储的内核数据相匹配mount。然后，由于您想要对驱动器进行低级访问，您必须以 身份运行root，使用sudo：
sudo umount /dev/sda1
sudo fsck.vfat -a /dev/sda1
选项-a要求fsck.vfat自动修复。请参阅了解man fsck.vfat其他选项。
