A disk drive has 1000 cylinders, 8 tracks per cylinder, 32 sectors per track, and 512 bytes per sector. The rotation time is 4ms. The read/write head takes 10ms to move between adjacent cylinders. A data file contains 200KB of data stored consecutively. What is the maximum seek time if the average time needed to read the data is 170ms?

Calculate how much smaller the raw video file of 40 GB would become if it were compressed with a compression ratio of 8. Express file size in megabytes.
A computer has instructions that each require two bus cycles, one to fetch the instruc- tion and one to fetch the data. Each bus cycle takes 10 nsec and each instruction takes 20 nsec (i.e., the internal processing time is negligible). The computer also has a disk with 2048 512-byte sectors per track. Disk rotation time is 5 msec. To what percent of its normal speed is the computer reduced during a DMA transfer if each 32-bit DMA transfer takes one bus cycle?
Consider a 4 inch disk with 64 double-surfaced platters rotating at 7200 rpm. It has a usable capacity of 16 gigabytes stored on 1024 cylinders. Assume 12% of each track is used as overhead with average seek time 10ms. compute the time required to transfer 8-K byte sector
Consider a disk with the following characteristics: block size 512 bytes, number of blocks per track=20, number of tracks per surface=400. A disk pack consists of 15 double sided disks. Suppose the disk drive rotates the disk pack at an average speed of 2400 rpm (revolutions per minute) i) How much time in (msec) does one disk revolution take? ii) Using the total capacity of the track as 10240 bytes how many bytes will be transferred from the track in 1 msec (ie transfer rate in bytes/sec)
With disks we can do complex calculations to see on what surface, sectors and track a file is, all from only the Block, calculate on which surface the following block is: 459621.
Suppose that a magnetic dick drive has the following characteristics: Rotational speed = 20000 RPM HTH switching time = 3 ms Average TTT seek time = 3 ms 6 platters, 1024 tracks per platter side recorded on both sides, 60 sectors per track on all tracks. Sector size = 512. The Questions are as following: What is the drive’s storage capacity? How long it will take to read the drive’s entire contents sequentially?
One disc makes 7200 revolutions per minute. There are 24 tracks on the disc and 8 sectors on each track. 2. A file saved in 2 consecutive sectors on the track and 4 consecutive sectors on track 20 will be read. The reader head of the disc is on the tenth (10) track when the reading starts. The transition time of the head from one track to another takes 10 ms. Assuming that there are 1024 bytes in each sector and the data transfer rate is equal to the rotation speed of the disk, what is the time to read one sector and read the entire file? 1,04 ms ; 274,54 ms C. 6,24 ms; 307,25 ms 8,3 ms; 180,75 ms 8,3 ms ; 298,5 ms
