Hi Woodmeister50, Apologize for the delayed reply. Other things in my life were taking priority.
I did run Disk Utility on the drive with an operation successful response and no fixes needed. I then tried both your Terminal commands. See screen shots of both below.


Both indicate removing .plist files. I did not feel comfortable doing that. I do not know where they live on my Mac Mini. I didn’t want to delete something else accidentally and cause more problems on my computer if I were able to locate them. I had removed .plists in the past with an Apple phone adviser’s help.
I spoke to a Senior Apple adviser this afternoon. He told me that they no longer do Terminal commands or instructions by phone with a screen share. I was told he would have to forward information to engineering in an apparent new policy. This would take time and he mentioned their solution could be updating the software to Mac OS 27. I do not like updating new OS software on the first release. Do not want to do beta testing.
He did have 2 suggestions to try first. I have another external SSD drive. He said to try reindexing that drive to see if I have the same problem. I did. Like my other drive the results of Disk Utility and both of your Terminal commands were exactly the same.
The other suggestion involved an app with a dongle that allows me to use my old iMac as a second monitor. He said uninstalling the app could help eliminate the issue. I would contact the company to see how to uninstall first and reinstall after the indexing if it works. I’d like to hear your take if this could work.
You have given me more information and help than Apple support. I would appreciate any further suggestions you may have, Thanks for all your input! Correcting this has taken a lot of time. I don’t understand why it should be this difficult when external drives have become so common.
Thanks, Charlie
