The developer of No Sleep has created a simple program that writes a blank text file every x minutes to the external hard drive effectively preventing it from entering sleep mode. The same can be done with a simple batch file or Autohotkey program but No Sleep is a solution for users without the knowledge to create a program of their own.

The software program is portable and comes with a graphical user interface that can be used to configure some of the program’s settings. The gui can be used to select the external hard drive that should be prevented from going into sleep mode and to define the write interval of the blank text file.

The interval can be set between 1 and 15 minutes. NoSleep mode can then be started with the click of a button. It is furthermore possible to place the software program in the Windows system tray to make it as unobtrusive as possible.

No Sleep should work on all versions of the Microsoft Windows operating system and with all kinds of hard drives that are connected to the computer system.
