I get error as below when I tried to start my Linux server.

/data contains a file system with errors, check forced.
Error reading block 77000497(Attempt to read block from
file system resulted in short read) while doing inode scan.

/data: UNEXPECTED INCONSISTENCY; RUN fsck manually.
(i.e.; without -a or -p options)
[FAILED]
***An error occured during the file system check.
*** Dropping you to a shell; the system will reboot
***When you leave the shell.
Give root password for maintenance
(or type Control-D for normal startup):


I need advise on this in order to get my Linux server to run

Go ahead and do what it says to do: Enter in your root password. That will drop you to single-user mode, and then you can run fsck on /data manually by typing fsck /data . When you do that, just say Y or whatever option allows you to fix it. If the drive itself isn't damaged, that should take care of things for you.
