摘要: A data reassign method in an embodiment includes: when a reassign command specifying a first logical sector that is included in a first physical sector and that has not been specified yet by the reassign command is received, reassigning data in the first physical sector to a second physical sector different from the first physical sector; and refraining thereafter from reassigning data in the second physical sector until occurrence of either re-receipt of the reassign command for the first logical sector or second-time or later receipt of a reassign command for a second logical sector other than the first logical sector included in the second physical sector.

摘要: According to one embodiment, a controller of a magnetic disk device starts to receive first data specified in a first write command from a host, and starts to write the first data to a disk in accordance with the first write command. The controller reports a status for execution of the first write command to the host depending on whether or not a second capacity of data not yet written to the disk is less than or equal to a first capacity of a first free space in a nonvolatile cache. The first free space is available to save data during a first period when a backup power supply enables power to be supplied. The second capacity decreases as writing of the first data to the disk progresses.

摘要: According to one embodiment, a read/write apparatus includes a receiver and a refresh module. The receiver receives a write command requesting a write to a magnetic disk. The refresh module refreshes, when a first area of the magnetic disk includes a second area corresponding to the write command, data written in a third area, the third area being an area obtained by excluding the second area from the first area.
