Keep your drives alive

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 is supposed to help 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 long 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 your drive from going into automatic standby mode

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 file that will be created, as well as click the 'Start' button.

Prevent Disk Sleep creates the text document with the given name. It's placed inside the specified folder in the selected disk, so it shouldn't be difficult to track down. The application 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!

Simplicity and Excellent.
I have been looking for something to keep my external drives awake for ages. Vovsoft provides a simple application that does just this and it works great. Immediately sent them a small payment to show my appreciation.
Life at my computer with my many computer hobbies and many external drives is literally 100% improved.

Prevent Disk Sleep is a beautifully simple and unintrusive utility that does exactly what it says. It’s been a lifesaver for me trying to use an external hard drive with an Avid editing system. Thank you

Thank you so much for this wonderful App. My 10 tb drive went to sleep after every 2 mins. It was driving me crazy. I nearly threw it out of the window several times but this has finally solved that problem so thanks again and keep up the great work :)
