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.
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!
External hard drive going to sleep and causing audio dropouts, after leaving system idle. Computerized audio synthesis stores data in ram, once that is no longer sufficient, it seeks out more data out on a designated data drive and needs the data instantly. If the drive is sleeping, there is an audio dropout. Just hitting the start button in this app solves the problem. It wakes up the drive and you’re ready to play! The user can then just close the app, or stop the app, so the music apps have all the system resources. 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 grateful! HDD is always ready to do the work i want! Thank you.
