Abstract
A method for maximizing buffer usage in a disk drive system. Control circuitry within the disk drive system tansfers the defective sector list for the disk to a buffer, and places the list in a reserved list area. The size of the defective sector list is then determined and the reserved list area is reduced to a size equal to the size of the defective sector list plus some spare room. If the newly sized reserved list area is not at one end of the buffer, it is then moved to one end of the buffer to leave the remainder of the buffer as a contiguous and expanded reserved user area for use data. The expanded reserved user area reduces the time of read or write operations in a disk drive.
