Ah hah ! We've stumbled into the truth.
What I'm trying to open is a Western Digital app. that is my access to all the backed-up files on the EHD. These are my personal Word, Excel, etc. files & folders. My Outlook Contacts; my Firefox Bookmarks, etc. And also my radio "log" of communications that day.
I do a nightly back-up. And verified that last night's back-up was OK.
The big OOPS is: I didn't download the Western Digital backup software that controls the EHD.
And the DESKTOP in the Ownership stuff is correct. It says the file in DESKTOP (previous) is now the owner of DESKTOP (new).
I need to take my meds (I'm 76, in poor health) and go back to bed, to have a clear head. Later this morning, I'll install the 3rd party EHD WD software, and try again to access my files on the EHD.
I'll stop the Take Ownership process. Will ping you after the WD EHD File Explorer tests...
Humbly,
Gary
