Windows 10: Files disappear from a second drive after reinstalling OS

Two weeks ago my primary hdd, a Samsung 850 Pro 1TB died, but I wasn't very worried being the drive in warranty and having a second hard drive (a WD 2 TB) where I store photos, documents, saves and other important files.
I proceeded to reinstall the OS on the new drive and something weird is going on; on the second drive many files just disappear, like it was restored a older version of the content. Basically latest files are time stamped june 2015.
I tried different recovery programs with both light and deep scan (Data Rescue 3, Ease Recovery, Getback, ecc.) but none of those programs can find any trace of the files I am looking for and I am going crazy to understand what is going on.

The only difference is that I am using a different SATA port on the MB than before.

Any suggestions?

Thanks

Lost directory and files in Windows 10

Do only files on the D: drive disappear after a few seconds?

 

Internal Harddrive disconnects and game freezes in game.

I just recently cleared out my storage to free up space and crucial files were deleted. I then had to just reinstall windows 10. After that it was updated and another update about a day later occurred. After reinstalling windows my internal secondary hard
drive that has everything except my os and a select things has been disappearing. It disconnects while I'm using files inside of it and then shuts everything I'm using down. I have to go to device manager and make it scan my hardware or restart the computer
to get it to show back up. The second problem is that while I'm in a game, if the hard drive hasn't disconnected itself. I get my whole screen frozen every 10 seconds or so. Only while playing games though. Ive tried updating my GPU drivers but it still has
the same problem.

 

Did you disconnect your 2TB drive before reinstalling Windows?

 

When reinstalling an OS on a new drive it's always recommended all drives be disconnected except the drive you are installing to.

However, if you made sure you installed to Disk 0 "which should have been the 850 PRO" Windows probably created the necessary partitions for proper install.

Recovery
System
MSR Reserved
Primary Partition 1

So in your install program you probably seen Disk 0 as unallocated space, and Disk 1 as the 2 TB drive. If you didn't do anything with Disk 1 "2TB" Then it should have been OK.

 

I'll keep in mind for sure for the next time...
I was suspecting also some problem about partitions... Indeed the drives before the damage were:

disk0 = Samsung SSD with the 4 partitions
disk1= WD 2TB with datas

after installing the new drive I switched the SATA port and the two diskid switched with having 0 for datas and 1 for system. Also, when I reinstalled, the drive D was without letter, so i had to assing it through admin panel, but since the disk structure was identical I didn't check the content until I had to.

Said so, even if it is a problem of disk table, how it is possible that a surface scan cannot recover any file?
There is a way to recover it? Does connect the disk as an external drive on another PC would help?

Thanks
