Keep a hard drive from going to sleep.

This uses the brute-force method of periodically reading random sectors.

To change the drive letter and timing, manually edit the source code.

Edit no-sleep-hd.py and customize the two variables:

EXT_DRIVE_NAME = "B"
PERIOD_SECS = 90

Tested 2025-03-17 with Python 3.7.4 on Windows 11:

• You may have to install Python.
  • The necessary program Pip should already be installed alongside Python.
• double-click the file create-py2exe.bat

A new dist directory was created from the setup. All the files within are necessary. You can rename this directory and move it elsewhere if you wish.

• Go to the new dist directory.
• double-click the file no-sleep-hd.bat.

• Exit the program with control-c or close its window.
• Then delete the files or directory.

If you just want to restore the files back to the pre-compilation state, you can run the cleanup.bat file in the dist directory.
