How can I solve the problem that fsck cannot be mounted on a debian hard disk?

Solution to the problem that the debian hard disk cannot be mounted to fsck-Debian technology-For details, see below. My machine is a dual-system, a WINDOWS debian. Because debian is entered by default, the default debian startup interface is accidentally entered many times, so several times, I have to press and hold the "shutdown" button of the machine and forcibly close it when debian is started.

Finally, the following hard drive failure error occurs:

/Dev/sda7: unexpected Inconsistency run fsck manually

Fsck died with exit status 4

* An automatic file system check (fsck) of the root filesystem failed.
A manual fsck must be already med, then the system restarted.

Then, you can only enter the single-user Diagnosis Mode.

After logging in with root.

1. Enter the following command on the command line interface: fsck. ext3-y/dev/sda7

The disk will be repaired in lost + find.

2. Click "y"

3. restart the system.
