Problem Copying File to USB Stick: Ubuntu Linux error while copying to – the destination is read only USB

Summary

Most of the issues with writing to the USB stick came from file errors on the stick.  Linux seems more sensitive to that.  I stuck the problem USB stick in a windows box and repaired it.  It then worked 1 time and then stopped working.  I was then prompted with "format if you want to use it" message.   Link #2 shows the Linux tool that can check the health of the USB stick or any other drive.
