RedHat Data recovery from lost+found in centos6.2

Respective sir,
I have Centos-6.2 on my system(P-4,1GB RAM, 80GB hdd).While working on my system I just face one problem my all folder get symbol of lock so I go for open terminal but my terminal is also not opened.So I shut down my pc without proper way.After restart my system I got shell prompt.their is one message (Give root password or press Ctrl-d)
so I give my password I got root@system#Prompt which is saying run fsck manually without -a -p
so I run this option and again restart my system.In single mode user Here on root prompt I just type fsck -t ext3 /dev/sda3 and press enter that time I got warning message that checking mounted filesystem may damage your filesystem but I ignor the warning and I start file checking and pressing Enter continously. after some time I restart my computer and when I try to start in normal mode that time I got following error.
mount:/dev/sda3 already mounted or /sysroot busy
according to mtab,/dev/sda3 is already mounted on /syroot.
Kernel panic-not syncing:attempted to kill init! panic occured,switching back to text console

I know I myself created this problem by forcefully checking mounted filesystem. but after this I try take another hard disk in that harddisk I have Ubuntu 12.04 LTS I start ubuntu in single user mode and here when I try to mount the centos root partition (i.e mount -t ext4 /dev/sda3 /media) that time this partion is successfully mounted in my /media directory but when I open the /media that time their nothing except lost+found folder

Then after this I start my system in normal mode and when Idouble click on my centos root partition that time it is showing only lost+found folder in it no other folders are their so how can I take my system to its prevoius mode.

root@kiran-System-Name:/# dumpe2fs /dev/sda3 | grep -i superblock
dumpe2fs /dev/sda3 | grep -i superblock
dumpe2fs 1.42 (29-Nov-2011)
  Primary superblock at 0, Group descriptors at 1-2
  Backup superblock at 32768, Group descriptors at 32769-32770
  Backup superblock at 98304, Group descriptors at 98305-98306
  Backup superblock at 163840, Group descriptors at 163841-163842
  Backup superblock at 229376, Group descriptors at 229377-229378
  Backup superblock at 294912, Group descriptors at 294913-294914
  Backup superblock at 819200, Group descriptors at 819201-819202
  Backup superblock at 884736, Group descriptors at 884737-884738
  Backup superblock at 1605632, Group descriptors at 1605633-1605634
  Backup superblock at 2654208, Group descriptors at 2654209-2654210
  Backup superblock at 4096000, Group descriptors at 4096001-4096002

then I use
root@kiran-System-Name:/# fsck.ext4 -b 32768 /dev/sda3

here I got huge lines after that when I mount sda3 again in /media even their are so many file with names started with it.

Without advanced knowledge of your Linux distribution, you are not going to be able to recover your root filesystem. You should just re-install the OS or restore for a backup if you have one. Never, ever, fsck the root filesystem except from a rescue CD.
