Requests are not usually uniformly distributed. For example, a cylinder containing the file system FAT or inodes
Question:
a. Would any of the scheduling algorithms discussed in this chapter be particularly good for this case? Explain your answer.
b. Propose a disk-scheduling algorithm that gives even better performance by taking advantage of this "hot spot" on the disk.
