5. When does the progress bar start? it appears to not move.

If you clicked File>Restore but you are not seeing the progress bar moving it is because the capacity of the hard drive and the number of files on it.

If you are restoring a hard disk of 100GB, the time to show the 1% of progressive bar moving will be between 10 minutes to 1 hour.
In a 100GB hard drive, if the file number of currently displaying and the files that have been erased are large, then scanning and reading them may take a longer time. Therefore, moving the progress bar may take long time.
