Let disk request come to a disk driver for cylinders in the order 10, 22, 20, 2, 40, 6 and 38, at the time when the disk driver is reading from cylinder 20. If the seek time is 6 ms per cylinder, then the total seek time for the disk arm scheduling time algorithm (FCFS - First Come First Serve) is:

Consider a disk system having 60 cylinders. Disk requests are received by a disk drive for cylinders 10, 22, 20, 2, 40, 6, and 38, in that order. Assuming the disk head is currently at cylinder 20, what is the time taken to satisfy all the requests if it takes 2 milliseconds to move from one cylinder to an adjacent one and Shortest Seek Time First (SSTF) algorithm is used ?

You are the administrator of Windows 2000 Server computer. Your computer has a span volume that consists of areas on three physical hard disks on the server. The three disks support hot swapping. You regularly backup the span volume by using windows backup. One of the disk fail, you replace the disk with a new un-partitioned disk. You want to recover the span volume and disk data as soon as possible. What should you do?
You install your boot volume on volume C on your Windows 2000 Server computer. You mirror volume C on dynamic Disk 1. Two years later, during routine server maintenance, you open Disk Management and find that the status of volume C is Failed Redundancy. The status of Disk 1 is Missing. You attempt to reactivate Disk 1, but the status of volume C does not return to Healthy. What should you do next?
Your Windows 2000 Server computer contains a stripe set with parity on a four-disk array. You convert the stripe set with parity to a dynamic RAID-5 volume. Six months later, users report that disk access on the server is slower than it had been on the previous day, You use Disk Management and discover that the status of the third disk in the array is Missing. You want to recover the failed RAID-5 volume. What should you do first?
