Bug report

This is continued from issue #96721

I had this happen again. I have a script that's copying a file from my F drive to my C drive. Below is what I received using python 3.11.2:

2023-02-28 05:00:31,156 - aws_copy_backups - [INFO] - backup filename is F:\My Backups\New System Backup\\C_VOL-b047.spf
2023-02-28 05:08:55,071 - aws_copy_backups - [INFO] - file F:\My Backups\New System Backup\\C_VOL-b047.spf is closed
Traceback (most recent call last):
File "startup.py", line 139, in run
File "console.py", line 18, in run
File "aws_copy_backups_main.py", line 433, in
File "aws_copy_backups_main.py", line 393, in main
File "shutil.py", line 213, in copyfileobj
OSError: [WinError 433] Invalid argument

I googled WinError 433 and it sounds like that external drive was disconnected, so that solves the puzzle. Thanks for putting the code mentioned in the previous post in python 3.11.2 shutil.py. I don't have to copy it anymore. I appreciate that. I thought I bumped the hard drive, but it happened early in the morning and I'm not sure I did. Maybe I need to buy a new external drive if this keeps happening. Thanks so much for the help.

So this is just an FYI.

Your environment

• CPython versions tested on:
• Operating system and architecture: Windows 10 64-bit fully updated.

@eryksun You said to open new issue when error occurred again.

Thanks for the followup report. It's good that you were finally able to diagnose the problem.

We should start supporting _doserrno for our internal CRT calls such as _wopen(), close(), read(), and write().

Yea, I had to buy a new external drive. That was the problem.
