I'm having trouble entering data into the report proper, so entering it in a comment:
CPython version 3.12b1
My environment: Windows 11 laptop 64bit

Using pathlib.is_dir for a directory on a mounted USB drive answers False, but os.path.isdir gives the correct answer: True. pathlib.is_dir works fine for the C:\ drive.

Attached is a little program that shows the problem.
is_dir.py.txt

Oops, I left this out:
My output from the attached program:

python is_dir.py
using os.path: True
using pathlib: False
using os.path: True
using pathlib: True

This issue should be resolved by fixing gh-104820.

Yep, can see this was reported first, but I've already attached the fix to #104820, so closing this as a duplicate.
