Control device, storage device, and control method for storage device
A storing unit stores initial parameters indicating initial values of control parameters in a first storage medium in association with first update parameters obtained by modifying the initial parameters. A difference detecting unit compares, when second update parameters are stored in a second storage medium, the initial parameters with the second update parameters, and detects a parameter that is different between the initial parameters and the second update parameters. An initialization unit initializes the first update parameters based on a result of detection by the difference detecting unit.
