For a couple of years I've been copying external HD #1 to external HD #2, and haven't run into this problem until now. I've searched through the Help documentation and tried to resolve it on my own, with no luck.
This is the error:
rsync: failed to set permissions (on external HD #2) - permission denied (13)
I only use one computer, and I am the main user/administrator. I completed this step in the help documentation:
Sharing and Permission privileges are set to 'Read/Write'
Can someone help me solve this error?
