Abstract: Methods, systems and computer program products for detecting an end of a reference spiral band are described. A first portion of servo information may be written on a disk using the reference spiral band. By detecting an end of a reference spiral band, a new reference spiral band may be launched. A read/write head of a hard disk drive may subsequently use the new spiral band to write the remaining portion of the servo information, which aids the writing of data tracks on the disk.

Abstract: A drive control module of a solid-state drive (SSD) includes a first module that receives host commands from one of a host command buffer and a drive interface of the SSD, converts the host commands to stage commands, and determines whether to store the stage commands in a stage slot of a staging memory or leave the stage slot empty. A second module transfers data between a buffer and a flash memory based on the stage commands. The flash memory comprises flash arrays. A third module detects a first empty stage of one of the flash arrays and based on an empty stage timer value triggers at least one of an end of the first empty stage, a start of an at least partially full stage of the one of the flash arrays, or a start of a second empty stage of the one of the flash arrays.
