My brother u can recover ur data very much.
1st. Make sure u do not copy any thing onto the formatted HDD. Do not put any new file on it till u have recovered all ur data.
2nd. Search for Majic Recovery Software Demo on the net and download it. The crack shld be available too if u search deligently
3rd. U need to install Majic recovery and crack it on another system or hard disk with an operating system of course (that hard disk or system must have enough/adequate free space to back-up ur lost files from the affected Hard Disk)
4th. Slave ur HDD to this new system
5th. Read the instructions of Majic Recovery tool and use it to search and recover ur files that went when u mistakenly formatted
NOTE : Do not back-up ur files/data onto the same Hard Disk that is affected while using Majic Recovery. Any new data
that is saved on the affected HDD before recovery is complete will erase the lost files FINALLY
GOOD LUCK !!!
