Recover data from full format on NTFS partition
Solution 1
GetDataBack is a spectacular program that works on both FAT and NTFS. But it costs money, 80 dollars to be exact. It's completely worth it in my opinion, but maybe your looking for something free.
Life hacker has a few ideas that you might try, but i haven't tried any of these.
However, no matter what you use you CANNOT install it on the same hard drive, even a different partition. Install it on another PHYSICAL hard drive and then try to recover it by copying the files to a separate drive than the one you are recovering.
Solution 2
Before trying any recovery tool that you can find, or that will be suggested on that page, the first thing you have to do is an image of the partition you want to recover (with dd for instance, you'll find it in any serious linux distribution/liveCD). Then, use the recovery tool on the image you have just made, and not on your hard drive directly. It will prevent that you / your tool destroys accidentally your last chance to recover your data.
Solution 3
Testdisk and Photorec may be of help, but they are a little advanced.
Solution 4
When you format a drive fully, it resets the data bits back to 0, but what that really means is that it discharges the polarity of the bit. However, it doesn't do this 'perfectly'. After many write operations, the bit can be in a state between 0 and ~0.4 charged (a simplified explanation of what really occurs) and still be considered deleted (or 0). So, to recover the data, you would need the ability to 'amplify' the charge state of the bits on the drive to recover them - this is only possible because you've applied a (rather) uniform discharge pass by writing 0's in the format process.
The reason that you can do a quick format or delete files in the OS and still recovery them is for two reasons. 1. NTFS keeps a secondary copy of its file list in the physical center point of the drive and these programs can recover the deleted entires and recover the files. 2. When you simply delete a file, only the file table record is updated and the data on the drive still remains (like chapters in a book that are no longer in the table of contents). Recuva, R-studio, GetDataBack all use these techniques to recover data.
I don't know of any software on the market (to the general public) that has the ability to do this. I'm sorry, but I don't think your data is recoverable in its current state.
tl; dr - data is not recoverable unless you have very high-end software/equipment, an electron microscope, or a buddy at the NSA/FBI.

I have a harddisk with two partitions: one for windows and one for data. I've reinstalled windows on the first partition and formatted the data partition with full format (without /Q option) making sure that all my data is backed up. After that I've created the same folder structure (without files inside) on data partition as it was before formatting.
I then realized that all my photos were NOT backed up :((((
I've tried several tools to recover my data without any success:
- Wordershare Photo Recovery
- Active File Recovery
- R-Studio
- PhotoRec from CGSecurity
- Recuva
There are max 50Mb of new data on that partition, so data overwriting is minimal.
What is the reason why I'm not able to recover my data with data recovery tools: full format or same folder structure?
And... can I get my photos back or they are lost forever?

alpha over 13 yearsFull format was used... that's a destructive format, overwriting every sector, I imagine it took quite a while to finish too. I'm afraid there's little that can be done. Had a /Q uick format been used, the data would still be in the sectors, just 'unlinked' in a sense, and quite reasonably recovered with the myriad of tools suggested. Full format wipes the drive, non-recoverable without majorly expensive systems and tools.

therube about 13 yearsThat may be true in XP, but it is different in Windows 7. 7 zero writes the sectors (when a full format is done). OP didn't provide OS info, I don't believe. If W7 & if full format, I believe the OP is out of luck.
