How do I Recover the Pictures and Videos?

http://askubuntu.com – I had FOUR NTFS partitions on my drive. One on which Windows 7 was installed (C Drive) and the other contained my data (D Drive) (E Drive) (F drive) . During Ubuntu installation I chose to install Ubuntu and erase my existing OS. When Ubuntu was installed, I was shocked to see no partition. All my data was gone. I must have done something wrong in selecting my option during installation. Well I actually tried testdisk in my other pc with the hard drive. I messed up with the thing I deleted the Ubuntu and made a single partition. Is there any way I can recover my D Drive? I don't care about (HowTos)
