DIY Data Recovery
The data present on a hard drive can be recovered using software if the damage is limited to small portions of the drive. The first step in recovering your data will be to create an image of the data on the hard drive. The image will then be scanned by the recovery software to try to get the data back.
Instructions

Creating Image

1
Download a whole-disk backup software program. Choose one that can make ISO images, as ISO is a standard any recovery software will be able to read.
-
2
Use the software installer or your burning software to create a CD/DVD of that software. Make sure to use the “Burn image” option of your burning software.

Insert the CD/DVD in your CD/DVD reader as soon as the computer is turned on. The software will start automatically.

Tips & Warnings
You can use only one computer by using another hard drive and installing a new operating system on it. Do not re-install anything on the hard drive you want to retrieve data from. You must use a software that is designed to read the file system you are using. Windows uses NTFS, OS X uses HFS and Linux can use EXT2,3 or 4.
Do not use a damage hard drive as a system drive, even if the damage is limited to a non-system partition.
