To simplify my last mail: going by all the information you gave, testdisk
should not have the slightest problem restoring your file.
If it can't, find some other tool that can analyze FAT cluster chains,
the first cluster of your file obviously has not been overwritten, thus
at the very least the FAT still contains the data where the second cluster
of your file is.
PhotoRec just is the wrong tool for large data stored on FAT.
