Abstract
According to one embodiment, A storage device includes a magnetic disk, a head, and a control unit. The magnetic disk includes a plurality of physical sectors having a first length. A logical block having a second length shorter than the first length, and a redundant area having a length of the difference between the first length and the second length are assigned for the physical sectors. The head reads the data from the physical sector of the magnetic disk. The control unit controls to change the second length of the logical block while maintaining the first length of the physical sector in response to reception of a change request for changing the second length of the logical block from a host.
