fsck exited with status code 4

Ubuntu 在启动的时候出现如下错误提示：

[ 1.910988] radeon 0000:01:00.0: VCE init error (-110)

fsck from util-linux 2.26.2

/dev/sda1 contains a file system with errors, check forced.

/dev/sda1: Inodes that were part of a corrupted prphan linked list found.

/dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

(i.e., without -a or -p options)

fsck exited with status code 4

The root filesystem on /dev/sda1 requires a manual fsck

出错原因：sd卡损坏，磁盘检测不能通过，可能是因为系统突然断电或其它未正常关闭系统导致。

解决方法：

根据上面的错误提示，可以发现是sda1卡出错，对sda1卡进行修复：

fsck.ext3 -y /dev/sda1

完成后重启电脑就可以了。
