Abstract
  • Disk space fragmentation is the proliferation of small and unusable gaps. This problem is considered within the context of IBM's VM operating system. Facing this problem, researchers resorted to using algorithms based on memory management techniques, such as placement strategies (first-fit, best-fit, and worst-fit). Solutions based on these algorithms do not yield optimum results. Furthermore, in many cases, their efficiency and cost effectiveness are questionable. This work proposes a new method to address the disk fragmentation problem using improved I/0 techniques. Optimum results and efficiency are some of the qualities that contribute to the superiority of this approach. The algorithm was implemented and test figures were compared with calculated figures. The results clearly favor this new algorithm.
