Abstract
A method and system for power management of storage drives. The method includes selecting an initial predetermined dual bit pattern that corresponds to a select power state of the storage drive, for providing to a first and second bit pin of a bit pin pair of a power control circuit that respectively connects to the storage drive. The method includes providing the initial predetermined dual bit pattern to the power control circuit which generates a discrete signal to the storage drive. The method includes encoding the initial predetermined dual bit pattern on the first bit pin and the second bit pin to selectively implement a power change on the storage drive in response to identification of a fault condition. In response to detection of the fault condition, the method includes selectively managing power to the storage drive based on input of the discrete signal.
