Question: So about a month ago I switched out my motherboard from a Gigabyte B450 Aorus Pro to an Asus x570 TUF. This switch caused 3 of my drives to become unallocated, which I was pissed off about, but I did successfully recover my important files using EaseUS. However today I uninstalled RGB Fusion 2.0: the thing that controls RGB for gigabyte motherboards, while also installing ASUS Armory Crate (which controls RGB for my motherboard). This immediately caused 3 of my 5 drives to become unallocated (one 4tb mechanical HDD, 1tb ssd, 500gb mechanical hdd in a hot swap bay). It’s literally the exact same thing that happened before, but this time I would like to solve it without having to format and recover data (if possible). I suspect that whatever tells the drive that it’s NTFS or exFAT or whatever just became corrupted, and all my data should be there just fine. I would just like to be able to access it.

Here are the important specs:
-ASUS X570 TUF
-RTX 2070
-GT 1030
-Kingston M.2 as a boot drive (still fine)
-2x 4tb I pulled from an old external drive (one is fine, the other is not)
-1tb Kingston SSD (unallocated)
-old 500gb i pulled from an older computer (unallocated)

I installed DMDE to my C drive and it shows the file system type and the name of the partition that I had on it before it became unallocated, i can provide screenshots if needed but I’m posting this from a different computer. Thanks in advance

Answer:Another victim of AMD Ryzen. 🙁 Well, at least that appears to be the common factor.

DMDE should be able to fix the problem with a few clicks, provided that you haven’t messed with the drives.

Screenshots would help, but normally you would r-click the desired partition and select “Insert the partition (undelete)”. Then Write -> Apply Changes and reboot to allow the OS to redetect the drives.

You may need to “Set GPT+MBR Signatures (GPT On)”, depending on the damage.

The whole procedure should only take a few minutes. There is no need for a full scan.

I should add that these procedures only target sectors 0, 1 and 2. They do not touch your data.
