Modern hard disks are set to automatically enter sleep mode (also known as idle time) whenever file operations are no longer happening. This is a method that helps with cooling the physical disk and prolonging its lifespan. However, if you wish to prevent this from happening, for example if you want the disk to quickly respond to file operations even after remaining idle for longs periods of time, then you can tinker with the built-in settings of your machine to turn off HDD sleep mode. If you find this method to be tedious, though, then you can turn to software utilities capable of keeping the HDD awake by creating small-sized files just to be able to mimic user interaction. Such a program is Prevent Disk Sleep.
Designed with the casual user in mind, Prevent Disk Sleep is incredibly simple to use. It can be scheduled to create a plain text document (TXT) in any disk of your choice, whether it's local or external. After a speedy installation that requires minimal intervention, the tool opens a plain window which shows all options available. Once you identify the disks you wish to prevent from sleeping, it's necessary to pick the matching drive letters from a menu, set the disk write interval (in seconds, minimum is 10 seconds), edit the name of the TXT doc that will be created, as well as click the 'Start' button. The first step is creating the text document with the given name. It's placed inside VOVSOFT folder in the root of the selected disk, so it shouldn't be difficult to track down.
Prevent Disk Sleep doesn't create multiple files each time it writes to the disk. Instead, it updates the one document by adding date and time stamps. This is also helpful for logging its activity and finding out the exact time of each disk write. Whenever you want to disable Prevent Disk Sleep, simply stop the operation after returning to the main app window.

Your wonderful software utility, "Prevent Disk Sleep" saved my life!!!! My external hard drive had been going to sleep and waking up constantly, annoying me no end, but with your software everything is now fantastic!!!! Thanks so much!!!! Your Big Fan
Thanks for your Prevent Disk Sleep utility, it's exactly what I was looking for - my disk went to sleep after only 20 seconds of not being used, which resulted in e.g. impossibility of playing MP3, because there were pauses in the middle of songs. While other similar utilities could write a file to the disk in minute intervals (which was useless for me), your utility made it possible to set intervals in seconds - perfect! Thank you!
Thanks for this Prevent Disk Sleep! I had been running a scheduled backup program to a secondary HDD on my PC. This backup program couldn't write to the HDD because it would be asleep at the required time and would cause serious problems with my PC as a result. Sometimes the backup would simply fail and other times, more seriously, the OS would freeze up and was unable to shut down or reboot. The only way to get it operating again was to boot from an emergency disc and reinstall the OS from the backup. Extremely irritating and time consuming to say the least. Since using Prevent Disk Sleep I have not experienced any more of the mentioned problems and no problems at all with the program itself, which runs continuously in the background 24/7. Thanks again, my friends.
It saved my life! I am a video editor and a lot of time the sleeping disk was killing my time by freezing the whole program. Now nothing happens and i am very greatful! HDD is always ready to do the work i want! Thank you.
Thanks! Great and necessary thing. Especially when you have Windows 10.
