What file system is on your flash drive? Run mount command to see if it was re-mounted read only after the error. That will explain the locks.
Thanks designator. I don't have rsync so I couldln't do that, but here's the deal: when I took the flash drive off and put it back on the lock icons were gone.
I checked the run mount command and it's "read & write." (see 013 screenshot)But the flash drive is very old (It's only 125MB) and very loaded. see screenshot So I'm wondering if it's just dying of old age and overburdening. They're theories anyway.
A little more info. see screenshot 014. I replicated the copying. I noticed the copying stopped on a certain file (the one whose icon is blacked out in the screen shot--and it's yellow highlighted). That's where I got the output/input error. I tried 'retry' and still got the error. Then I picked 'skip' and the copying continued uninterrupted.
What happened was (see arrow) that file was already in that folder. So it was sensing it as a duplicate. Why it chose that particular file (because all those 'flash fiction tab photos' are in the folder) folder I don't know.
The results of the skipping was that the file has 0 kb. But it's still in the folder so no big deal.
Why the lock icon thing happened is still a mystery to me.
