I stupidly formatted my NTFS partition to FAT

#1 Post by jrbrooks » 07 Mar 2013, 20:58

I have a 1 TB disk which was partitioned into two 500 GB NTFS partitions and I have been happily using this structure for a couple of years. I accidentally formatted one of the partitions to a FAT partition (it was about 3 a.m. and I thought I was formatting an external hard drive); in fact, I may have formatted twice.
Now, using GParted and Testdisk I can see one of the original NTFS partitions intact and the rest of the disk is broken into about 4 blocks - one large NTFS and 3 others of FAT or EXT file type.
What is the best hope/procedure for recovering the original NTFS 500 GB partition? This partition contains all of my photos for the last 15 years (among other things). Should I try Photo Recovery?

I do not understand which menu option I should select for the various blocks that are found. Since I know the structure that existed before my terrible error, can this knowledge be used to guide the recovery?

Is there a tutorial somewhere that explains the file structure, cylinders etc.etc.?
