Before answering how to recover data from formatted hard disk, I would like to explain "what is format" and "How is the security of data when formatting a hard disk?"
What is format?
In short, format is the initialization we have to do before taking use a hard disk. After this process, we can record information on the hard disk at easy. It is similar to storing many books in a big house. We cannot discard books into the house but put up a bookshelf firstly and place all books in categories. Furthermore, a computer operating system is not able to recognize a brand new hard disk or read data from it only when some magnetic symbols are written into every section of it. In the fact, the written process is format.
Format contains high-level format and low-level format. Floppy disk only has high-level format while hard disk has not only high-level format but also low-level format. Low-level format is subject to hardware tracks, and usually done before partition and high-level format.
Here I just help you distinguish the two by a simple method. Format which is related to operating system is high-level format. On the contrary, format that is not related to operating system is low-level format. In our daily life, the format we usually said is high-level format in most cases.
How is the security of data when formatting a hard disk?
Theoretically, high-level format does not erase the data actually. It just marks the head of section where data locals by a kind of symbols telling operating system that this section is new data storable. In this case, we still have a chance to recover all data from formatted hard disk so long as there is no new data stored on after formatting. What we need is just a data recovery tool, for example Wondershare Data Recovery (http://www.disk-utilities.com/data-recovery/index.html). So once you found you accidentally formatted hard disk, please to ensure that the formatted hard disk is not overwritten.
Ok, now let me show you how to recover all your data from the formatted hard disk step by step.
I take Wondershare Data Recovery for instance because it's easy to use for green hand. You can also search many other data recovery tools by yourself. Click here to get the free trial of Wondershare Data Recovery (http://www.disk-utilities.com/data-recovery/index.html).
Step1. Install Wondershare Data Recovery
I have to remind you that you do not install Wondershare Data Recovery to the same partition where you lost data for avoiding overwriting the formatted hard disk.
Step2. Select the formatted hard disk to scan
When you open the application, you will find there're four options for recovery. Choose the second, Format Recovery, and then select the partition you formatted. Next, you can select the file system for your formatted hard disk or just left as Auto Detect.

Step4. Select or enter a path for saving recovered data.
We highly suggest you never to select a path that is located in the formatted hard disk that you're searched data from, in case it would eventually overwrite the source data.
