That nothing looks to be lost. However the error messages are well discussed so I won't tackle them all.

Except that one -> "the directory or file cannot be created."

This one is common on drives that the top directory has become full. To get around this, remove some file or folder and create a new folder then put your stuff in folders in that folder.

-->> But that's not why I write here. It appears you are repeating the BIG MISTAKE many make and that is to think this thing is STORAGE. It's not that reliable so keep a few spare copies on other media and locations of what you can't lose.
