Abstract
A write command is received from a host computer at a disk drive having a disk. The write command is associated with a data block and a logical block address of the data block, and a logical sector size of the data block is smaller than a physical sector size of a physical sector on the disk associated with the logical block address. The data block is written to a staging sector located in non-volatile media of the disk drive based at least in part on the logical sector size being smaller than the physical sector size. A write response is sent to the host computer, the write response indicating that the write command has been completed. After sending the write response to the host computer, the data block is written to the physical sector on the disk.
