I use shutil.copytree to copy photos from many sd cards to a hard drive.
I use thread for each sd card. then I check if the content has been copying correctly with filecmp.cmpfiles with shallow to false. and surprise!!!
some files are not identical. usually, just one byte has not been properly copying

This looks much more like a hardware problem than a Python bug.

In the future, please post text instead of images.
