Assume that a given hard disk is running at some certain speed so each block can be accessed within 1 micro-second, and the speed of the step motor is 1 micro-second per track and each track contain 4096 blocks. Assume that there are a few I/O requests arrived before t=0: and block numbers are given as {#32410, #12345, #662275, #88835}. Assume that the read/write header is located at track #100 and block #1234 at t=0. Assume that the device is running in a first come first serve manner. Compute the time needed to finish all these I/Os. Note: you need to calculate the track # and block # for each targeted block. process chart also needed if possible.
