I need your help to see if it is possible to recover the data from a HDD that I accidentally damaged using diskpart. Well I explain in summary how everything happened. A couple of days ago I decided to install Windows 10 on a SSD (120GB); besides that SSD I have a HDD (1TB) where I have all my files stored. But first to install Windows 10 I needed to convert the SSD from MBR to GPT. So I did this from the CMD:
Then I went back to the installer of Windows 10 and in the part where it asks you to select the unit where you are going to install Windows I realized the damage I had done. Not only I was not able to convert the SSD to GPT but also accidentally deleted the volume of the HDD (1st partition of 900gb) where I had my files; the 2nd partition was not damaged.diskpart
list disk
- disk 0 (SSD) 120gb
- disk 1 (HDD) 1tb (it has 2 partitions, the 1st in 900gb and the other 100gb)
select disk 0
clean
create part pri
select part 1
format fs=ntfs
select disk 0
detail disk
select volume 1 (this is where I think I made the mistake, volume 1 was the 1st partition of disk 1 HDD I think, I didn't check it)
delete volume
convert gpt (here it gave me an error and could not convert to GPT)
I took a capture in Linux of the current state of the HDD. You can see the "sin asignar" (unassigned) partition with 833.86 GB.
Is this recoverable using TestDisk? and if so, Is these the correct steps I should follow?
Sorry, I just want to be sure that I'm doing it correctly.- Run TestDisk as admin
- Select a disk (In this case dev/sdb)
- [ Intel ]
- [ Analyse ]
- [ Quick search ]
If it finds it.
- A: add partition
By the way, I already managed to convert the SSD to GPT and install Windows 10 correctly, but this time of course, I did it by disconnecting the HDD to avoid doing more damage. Currently I still have it disconnected.
I would appreciate if you could help me. Thanks and regards.
. It was very easy too. All my files seems to be fine. Lesson learned. In the future I will be more careful hehe
