Cannot add a Drive to Indexing Options

Hi. I’m hoping someone can tell me how to get my E drive indexed for searching purposes. As you can see from the pic, it’s just not ‘addable’…

I have an SSD dedicated to the OS and two HDDs (E and F). I recently had a problem with some files on the E drive in that I was denied permission to change their details so I changed the ownership/permissions. However, both E and F now have the same Owner/Permissions settings so it can’t be that (can it…).

Any help is greatly appreciated.

Yes (rebuild) and Yes (troubleshooter) - both had no effect. I'm currently running chkdsk E: /f /r /x which means a wait of 6 hours...

Properties/Tools/error checking immediately said it saw no problems. I'll wait for chkdsk to finish and then see what's what, I think. I'm sure the disk is good, too much of a coincidence for it to go just after I've clean installed Win10...

Twelve hours that took... No errors found. A reboot later and my situation is the same. Apart from the copy off/reformat/copy back suggestion (which I'll delay for now) is there anything else I might do? Thanks.

I forgot to mention that I ran Tweaking.com – Windows Repair as suggested above. It had no effect.

Hi AndreTen and thanks for the tip. I haven’t run the wizard yet as I’ve noticed something (possibly) interesting. When I did my clean-install a week ago, I unplugged the E & F drives and took the opportunity to do a UEFI install. I knew that this would change the C drive from MBR to GPT but look at the pic – my 4TB E drive is also GPT. I suppose it must always have been like that as I’ve never touched it.

Could this be a clue as to why it’s not indexing? Seems unlikely to me as it’s never given me an indexing problem before.

My continued thanks.

OK, thanks. Is that partition wizard of any use to me then? If not, what else might I try?
