Disk error during linux Startup

Disk errors during linux Startup: Linux general technology-Linux technology and application information. For details, refer to the following section. /Home contains a file system with errors, check blocks.
/Home: Group 81's inode table at 2654219 conflicts with some other fs blocks.
/Home: unexpected inconsistency; RUN fsck MANUSLLY
(Ie,? A or? P options)
* ** An error occurred during the file system check.
* ** Dropping you to a shrll; the system will reboot
*** When you to leave shell ....
Give root password for maintenance (or type Control-D for normal startup ):

This indicates that your filesystem may be subject to disk space disorder. In general, such disk space disorder should not be a real hard drive error, but may be caused by Inconsistent filesystem (Inconsistent) caused by the shutdown of the disk). After this problem occurs, you must enter the root password, run level 1, and then use fsck/dev/hd [ad] [1-16] to fix the disk. For example, if/home is mounted to/dev/hda6 in the above case, I will "fsck/dev/hda6" without adding any parameters. When an error is found and "clear [Y/N]" is displayed, enter "y!

This process may take a long time, and if the filesystem on your partition has too much data to be damaged, even if the fsck completes, it may hurt the system slot, as a result, some critical system archives are damaged and cannot be accessed to Linux. In this case, you just need to copy important information from the system, reinstall it, and check whether the physical hard drive is damaged! But in general, it is unlikely that this will happen. Generally, after fsck processing is completed, it will be able to enter Linux again.
