Drive Keepalive is a simple Windows 11 tool that prevents your hard drive from going into automatic standby mode. It works by writing a small text file to your external drive at regular intervals, such as every 180 seconds or any custom interval you choose. You can add multiple drives and configure the tool to start automatically, so you do not need to set it up again every time.
Drive Keepalive is useful for external drives, especially 3.5″ hard drives, that often go to sleep after a period of inactivity. When Windows accesses the drive again, it has to wake up first, which can cause delays, freezes, or unnecessary lag. This tool helps keep the drive active and avoids those interruptions.
