Just finished this app which stop's external hard drives from sleeping.
You add locations to keep "awake", set the interval at which to write (1-15 minutes) and go.
It supports multiple locations and loading at windows startup.
Once application is launched, it will start in system tray, double click the icon to show main window, add locations and click start.
If you have previously set locations, the application will automatically start writing to those locations upon launch.
It has an update feature, this is accessible through the system tray menu (right click icon > check for updates)
You shouldn't encounter any bugs but if you do, just post here and I'll sort them out.
