Abstract:
The various implementations described herein include systems, methods and devices used to protect data in a storage device. In one aspect, a method includes, performing a soft power fail operation on a section of the device, the operation including: (1) signaling a power test condition to a first controller on the storage device; (2) providing one or more controllers with power from an energy storage device, where the energy storage device is distinct from a power supply used during normal operation; (3) signaling a power fail condition to the one or more controllers on the storage device, where the one or more controllers communicate with the first controller and correspond to said section of the storage device, and where, in response to the power fail condition, each of the one or more controllers performs a data hardening operation; and (4) resuming normal operation on said section of the storage device.
