Abstract
An indication of a power-up of a storage device may be received. In response to receiving the indication, a first data structure that is stored at a volatile memory of the storage device may be retrieved. The first data structure may include first information associated with characteristics of a plurality of data blocks of the storage device. A second data structure stored at a non-volatile memory of the storage device may be retrieved where the second data structure includes second information associated with the characteristics of the plurality of data blocks of the storage device. A new data structure may be created based on the first information and the second information and a rule where an entry of the new data structure is provided a value from one of the first information or the second information based on the rule.
