Rewriting of data stored in defective storage regions into other storage regions
A storage apparatus includes a storage disk including a plurality of tracks each of which includes a plurality of sectors, a head configured to write data in and read data from the storage disk, and a controller. The controller is configured to control the head to carry out reading of a group of data units from target sectors in a target track of the storage disk, the group of data units being associated with a command received from an external device, determine whether or not the target sectors include one or more defective sectors based on result of the reading, and control the head to write the group of data units in physically consecutive non-written sectors of the target track or another track, when the target sectors are determined to include the defective sectors.
