Be aware that if you did a quick format and have not installed anything on the drive (OS, apps. and whatever else) there is a chance you can use a tool like the one above with various success. You never know what you will get until you try. However the success decreases with each item you may have installed. Each installation over writes sectors and clusters that contain the data you want. So do not use the disk until you try your recovery.
If you didn't write anything to the drive after formatting, you *may* be able to recover your drive using one of the MBR recovery tools on hiren's boot cd 15 which is free from here: http://www.hirensbootcd.org/download/
There is a list of the MBR repair tools, like Mbrfix 1.3 on the disk, listed here: http://www.hiren.info/pages/bootcd You can boot from the CD that is made from the Hiren iso image and then try the MBR repair.
The tools on the disk are easy to use, but if you don't have much computer experience you would be better off getting help.
Another option is to attach the drive to another computer and then use a file recovery program like Recuva, which is free and quite good.
