I recently upgraded my PC from Windows 7 to 10. I use a SSD as a primary drive. When I plugged the old drive back in the PC, I could only see the first partition of it. The second one, which was around 150GB in size and contained many important files, was completely gone. It's not even showing in the disk management. The 200GB drive now shows as a 40GB drive.

How do I get my lost files back?

"Klaustrofobia" is the one partition of the drive that works. "Muinaismuseo" belongs to a completely different HDD and works fine.

I would differ with you on this as both Klaustrofobia and Muinaismuseo are partitions on the same physical hard drive

I would say your SSD is not recognized and seemingly is DISK 1 (unknown) I would find the drivers for your SSD and install them reboot and see if that solves your issue.

Also you failed to mention what SSD you where trying to see once again

Actually the SSD is Disk 0 "Turbolevy". But you may be right about D: and G: being on the same drive. In that case, my other HDD (Disk 1) is apparently not working.

SATA. I actually managed to dig up parts of the files that were in the missing partition using EaseUS Data Recovery Wizard. I targeted the search to "Klaustrofobia" and found a lot of files, some of which I recognized to be in the missing partition. Almost all of them were unusable.

I'm now trying MIniTool Partition Wizard, full search, and it shows up as the preview unallocated space of 189.9 GB (If I recall correctly, that's the size of the missing partition). It doesn't show up in Windows disk management.
