自动挂载Ext4分区时，报错：

mount: wrong fs type, bad option, bad superblock on /dev/sda7,

missing codepage or helper program, or other error

In some cases useful info is found in syslog  try

dmesg | tail or so

当我尝试通过GUI挂载分区时，它给了我以下错误：

Unable to mount 80 GB Fliesystem

Error mounting: mount exited with exist code 1: helper failed with:

mount: only root can mount /dev/dsa7 on /media/80GB

dmesg | tail命令错误信息如下

修复磁盘安装错误

dmesg指出了有问题的部分。 uid = 1000时遇到问题。实际上，我已经编辑了/ etc / fstab文件，以包括以下行来自动挂载Ext4分区：

UUID=f920adf0-6038-4145-8214-4e1b79ca2d9b /media/80GB ext4 defaults,uid=1000 0 0

我用下面给出的行对其进行了更改，以删除麻烦的" uid = 1000"：

UUID=f920adf0-6018-4145-8314-4e1b79ca2d6b /media/80GB ext4 defaults 0 0
