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.
Image


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



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 ?

If you do care for the data STOP what you are doing right now !!! If you start to mess with partitions and volume types you will get that data lost for good ...

If you can't use the original PC and you are limited to USB adaptor only your chances for recovery are even lower.

I would try to plug the drive by SATA to a desktop and use something like R-Studio to see if i could copy the data out of the drive to another safe place.

There is the possibility that your drive is failing as well so you might want to play safe and clone the drive using something like hddsuperclone to another drive with the same or bigger size and then attempt to extract the data from the clone ...

And as always if the data is of great importance to you please do seek advice of a professional reputable data recovery firm as at this stage it should be a very cheap recovery and it's better than messing up and loosing the data for good ...

It seems your disk was not just a second drive letter in the other computer.

Consider all the advice already given by Spildit. It would probably be easier for you to expedite the fixing of the original computer, (without formatting/reinstalling OS in it ) then connecting your hard disk again to it.

Other than that, there is the risk if you format the SSD of the other computer, you may also lose the data in this, or at least make recovery of it more difficult ( and costly ).

AGREE !!!

Your drive apears to be "part" of a spanned volume so you might still need the SSD to access it as it might even work like some sort of RAID configuration, etc ...

It's NOT that your drive is a single drive with it's single partition and data, it's more like your drive + the SSD are sharing the totality of the space to store data randomly on it, so pieces of te same file might be on the SSD and HDD at the same time and if that isthe case running R-Studio on the HDD will not help as well...

Can you show us the Partitions window in DMDE?

https://dmde.com/

Can you also show us the contents of sector 0? Let me know if you need help with this.

Hi guys, thank you for your help.

@ Spildit & rogfanther : thanks for the explanations about the spanned volume, I had no idea about that. I'll play it safe I guess.

@ fzabkar : I'm not sure if this is exactly what you want, but here it is :

If you do buy a full version of DMDE you should be able to copy your files from the HDD partition (NTFS) to another drive.

Should be safer than attempting to "fix" whatever is "wrong" with that file system ...

The DMDE screenshot appears to be showing remnants of an earlier installation.

Obviously the data are in the "LDM data partition". The "LDM metadata partition" would contain information about all the drives that make up the dynamic volume. I have no experience with dynamic volumes, so I cannot suggest anything other than to attempt to reconstruct the file system with an NTFS search.
