CentOS 启动不了了

boobookelinux

哪位大侠帮帮书忙，小弟安装的是CentOS 5.3操作系统，可是在启动一半的时候却出现了如下代码：

fsck.ext3:Bad magic number in super-block while trying to open /dev/sda8          失败

*** An error occurred during the file system check
*** Dropping you to a shell,the system will reboot
*** When you leave the shell
*** Warning --SELinux is active
*** Disabling security enforcement for system recovery
*** Run 'setenforce 1' to reenable

   Give root passwd for maintenance
       (or type Control-D to continue)

  然后小弟输入的root 的密码之后出现了
   
    (Repair filesystem) 1 #


这是在我配制磁盘配额的时候，重启之后出现的界面，而且也没配成功。
/dev/sda8     /mnt/quota        ext3       defaults,usrquota,grpquota,1,1

   小弟不胜感激！
