I would like to clean up USB drive so that I format the drive and come back necesary file images were back. So I did not use convert. But thanks for your kindness. After formatting USB drive in NTFS format, chmod 600 works as expected. and $ python3.8 -m jupyter lab now works without any patch work. Thanks!
