DiskWakeUp is a small C# console utility designed to keep your hard drive awake by regularly updating a temporary file.
Some hard drives, such as Western Digital Black models, tend to spin down after a few minutes of inactivity. This can cause delays when accessing the disk. DiskWakeUp prevents that by simulating periodic activity.
The program creates (if it doesn't exist) a file named WakeUp.tmp in a specified folder and updates its last modified timestamp at regular intervals.
