Hello guys,

I had the following configuration:

Disk 1 SSD 120 GB
C: Windows 10;

Disk 2 - Internal HDD 1 TB
D: Backup ~ 931 GB

A few weeks ago, I partitioned the disk 2 into another unallocated 20 GB partition and tried to install Linux (Ubuntu Gnome) on it. I failed to boot the Linux (but it installed) and at that time, I was busy so I gave up. Then, since Windows default explorer have been showing my two ‘regular’ partitions (C and Backup D), I never realized that I still had that 20 GB partition with those files in there (hidden from explorer).
So, today, I was looking at Disk management and saw that old 20 GB partition where I installed Linux and made a HUGE mistake: I merged my Backup D with this 20 Gb partition and got a RAW disk. Immediately I realized the shit I had done, but it was too late, the system prompted me to format the disk “D” in order to use it, and I REFUSED it.
So now I have a RAW 931 GB 100% free, inaccessible, disk…
Well, I tried:
1. Marked the partition as active;
2. Chkdsk – not working on that disk;
3. Ran TestDisk on it and got a HFS NTFS partition that was unable to recover and some 2 FAT32 partitions that I could only fix the boot, so I left them untouched.
4. Ran LINUX ntfsfix on the /dev/sdb1 (931 GB disk unpartitioned disk). Got nothing.
5. Now, I’m running Active@ Partition Recovery and so far, I have the following screenshots.
I could find some pdf, jpeg and mp3 from the drive, but I don’t know from which volume they came from. My original backup disk was the onde called: “Dados”. So I tried recoverying it, but it says: Overlapped partition detected, and that I have to delete one of the volumes that are creating conflict.
