Are you sure during the installation process you didn't accidentally delete the partition & recreate it on the disk? It might well be worth going back to Windows 7 or booting off some kind of Linux Live CD to see if another operating system can view the data on the disk.
Do you have another PC nearby you can put this disk into to see if it can be read?
DON'T format it just yet...

i didnt format wrong disc. i am sure about that. i will try too put the hard disk too another pc for check the result.
P.S sory for my english. isnt my mature language....
thanks for the awnsers
