The partition was 8 Go but was nearly full so I created a new one at the end of the HD called "documents". after save and reboot, I got 2 uninitialized partitions (docs and documents). I thought that if I delete and recreate the docs partition, I should have everything back in place but no :( after sfsformat, I have now a totally empty partition even sfssalv sees nothing in fast and deep mode... are my scans lost forever ? why 2 partitions sharing some caracters would become uninitialized ?

The most likely reason is that you accidentially moved, changed the size or some other settings of docs. Especially moving partitions by accident happens very easy, if you click on a partition and move the mouse a little bit while still holding the left mouse button the partition is moved But HDToolBox should have warned you that the contents of the docs partition are lost in such a case.

After formatting it, especially if it didn't have the same settings anymore, there is probably not much left, if anything, which can be recovered.

I am quite sure I did not change the docs partition because it is in between 2 others existing partitions and moving was unlikely as well.

That way you can only be sure sure the low- and high-cylinder numbers are correct, but the rest of it (DOSType, BlockSize, Reserved, etc.) could still have been wrong. There are tools which can seach partitions on the HD and will display the corrct values for the partitions, but since you have formatted it they can only find the new, and probably wrong, values now and don't help anymore.
