How to recover your data when your disk is crashed.

When your Operating System is crashed and you have important data on that partition, do not Panic :)

Assume that there is Windows installed on C partition. And the machine can not be booted due to any error. You can rescue it using a Live Linux CD/DVD without much effort and knowledge.

_1_
Dowload one live Distro. For example Knoppix 5.1 (or any later version). Burn the image in a CD.
_2_
Boot your computer from that CD.
_3_
When your linux OS started, you will see that your partitions on Windows (C, D,..etc) are also mounted in Desktop(like sdax, sdbx..etc).
_4_
You can plug a USB disk in your computer. It will be automatically mounted. Be careful that you wont have read-rwrite access to that disk. You can give this access by right click on the disk shortcut on Desktop. If you are CLI lover, you can use "mount -f /media/sdb1 -o remount,rw" command with root permissions.
_5_
Now you can copy from windows partitions to your USB disk.

Do not forget to enjoy using a LINUX OS :=)
