What is the method for performing a hard reset on DALR?

The method for performing a hard reset on DALR involves powering off the system using the hard drives. This process typically entails cutting off power to the system in a way that forces all unstable operating conditions to reset. Hard drives, being integral components of the system, serve as a direct channel for power management. Disconnecting or powering off the hard drives effectively terminates processes that may be running and clears all temporary configurations that could lead to non-responsive behavior.

In contrast, simply restarting the computer application or software may not address deeper hardware issues that necessitate a hard reset—these actions would typically just refresh the software environment without resetting hardware states. Additionally, removing the power source refers to unplugging the power supply directly, which, while effective, is not the standardized method for a hard reset involving hard drives. Lastly, switching off the network connection might help with connectivity issues but does not have an impact on the internal hardware state that a hard reset aims to correct. Thus, using the hard drives for a hard reset directly addresses the core needs of the system in an effective manner.
