I am trying to back up my Home folder before upgrading to a new hard drive. I used Grsync to copy my home folder to the new drive in my USB SATA dock.

The folder and sub-folders all appear to have copied OK and File Browser shows that files in Music, Pictures, Videos, etc., are present.
The Documents and Downloads folders are shown as empty.

???

If I try to copy files manually using File Browser, it says the files already exist and do I want to merge/replace/skip, etc.
If I copy and paste to a differently-named folder, like "test" the files copy OK!

Any ideas what is going on here?
