A partition that is visible but not accessible, how to do it?

I have an old ASUS laptop initially running Windows 7 but upgraded to Win10.
It was slow so much that it was unbearable, I doubled the RAM to 8 GB instead of 4 GB and changed the HDD to an SSD.
 
It's day and night, the cell phone has found a real catch.
 
Basically it has 2 HDDs of 500 GB each and each HDD has 2 partitions
 
The 1st DD C: and D: is replaced by the SSD on which I installed Win 10
 
The 2nd HDD: when I open "this PC" it appears in C: the SSD and only one of the 2 partitions (SDATA2) of the HDD the SDATA1 is invisible but in the hard drive manager it appears.
 
I don't understand why this partition is invisible?
 
Do you have a clue to make it reappear without data loss?

    It sounds like you've significantly improved the performance of your old ASUS laptop by upgrading the RAM and switching to an SSD.

    Now, regarding the issue with the second HDD, it seems that one of the partitions (SDATA1) is not visible in the "This PC" window, but it's visible in the Disk Management utility.

    You've mentioned that in Disk Management, SDATA1 appears but is invisible in "This PC". This is usually due to drive letter assignment or mount point issues.
