Abstract

In some examples, sectors of a solid-state drive are unmapped to initialize the sectors. The sectors include a data portion and a protection portion. When an unmapped sector is read, the solid-state drive can return a pre-set value for the unmapped sector, where the pre-set value includes a known fixed value to represent the protection portion of the unmapped sector. The storage controller is to recognize the known fixed value returned by the solid-state drive responsive to the read as representing the unmapped sector as being initialized, but not written to.
