Windows 10: Windows 10 Indexing Options Drive Missing

I recently installed Windows 10 on a computer containing 3 internal and 8 external hard drives. Although all the drives show up in Disk Management and File Explorer, one of the internal drives isn't listed under "Indexing Options" so I can't get the files indexed. Since I can't get them indexed, I can't add them to a Library. I can access the drive, I can share the folders with my homegroup. I can view the files from the computers in my homegroup. I just can't add the relevant folder to the library! Can anybody explain this weirdness?

Search Not Indexing Optical Drive

Currently Windows 10 Pro is not indexing some files in my D Drive.

I have checked that the D Drive is being indexed. I have already:

• Rebuilt the index under the Advanced Options;
• Restarted the computer after adding the D Drive and Rebuilding the Index;
• Checked that File Types of Folders are not being excluded in Advanced Settings;
• Changed Index Properties to Index Properties & File Contents in Advanced Options and reindexed again;

Still many files are not showing from the D Drive.

Can anyone help me with this?

The image below shows the indexing options screen under settings - indexing options

Windows 10 indexing options shows that user has selected indexing location as Drive C

But the bottom half of the box "summary of selected locations shows

NET

Drive E

My query is why if C: drive is selected as indexing location doesn't C: appear in the summary

Is there an error ?
