Cant use my internal drive in external (USB)

[YGK13]

Hello,

I had got a problem recently with my main computer and I can't turn it on for the moment.
In order to be able to get back some data, that are really important to me, i bought an adaptator to use my HDD as an external drive, connected in USB to my laptop
(By the way, if that does matter : my HDD is a Seagate 2To 7200/min, that i use as a second disk on my main computer, for data storage mainly, while the OS is on a SSD.)


The thing is that even if windows does recognize the hard drive (see pic below), it doesn't appear as a hard drive.



I can see it in the disk management though : disk 1 on the pic, and windows tells me that it is dynamic.



I can see it through diskpart aswell, and here it says that the disk is invalid and that there is no volume on it




I already tried to see if I could access to the HDD with a linux live cd, the answer is no.


So I wanted to convert the disk from dynamic to basic, because I read that this is possible without losing any data.
I tried the AOMEI programs but it doesn't work (& I'm not sure about what it says to me about the possible data loss)

either i get this with the Dynamic Disk Manager :


either i get this with the Dynamic Disk Converter (can't proceed) :






I wanted to try the dskprobe method aswell (see : https://arstechnica.com/civis/viewtopic.php?t=726327 )
but I don't have a "42" at the mentionned line (see pic), so I prefered to not touch anything




I'm really stuck and really annoyed with this.
Could somebody help me pls ?

When and why did you span the HDD ? ?

This may be trickier than you think...

The drive was dynamic because it was spanned. A spanned volume is a volume that stores data across partitions on more than one physical disk. At best, that means you need all physical drives that were part of that spanned set in order to rebuild it. Alternatively, recovery software can often get data back from the physical drive that was part of a spanned volume, since data is not striped across the disks.

I would surmise that at some point or somehow you created a dynamic, spanned volume from unallocated space on your SSD and your secondary drive, perhaps while setting it up.

Hi guys, thanks for your help

@ patio
I never did this. I bought my computer online through a website that was specialised in assembling computers. I guess they did it. I had no idea about that (I didnt even know what was a spanned drive before).

@ BC_Programmer : thanks for explanations. As I said just before, I think its the guy who assembled the computer who did that.
So i could try something like Recuva ?
