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?

Suppose that a disk drive rotates at 8000 RPM. It has an average seek time of 4 milliseconds. If its transfer rate is 15 Mbps, determine the average time it takes for a 15K byte request to be transferred from the time the disk starts the seek? From this, determine its throughput.
A disk size of 200 tracks receives the requests for the blocks for I/0. operation. No. of blocks requested on disk are: 92, 154, 47, 31, 173, 74, 87, 23. Calculate the total head movements using FCFS and SSTF algorithms. Initially, the head pointer is at 53.
A computer system has a memory access time of 11.0 ns and is using a SATA III SSD (solid state drive) capable of transferring 8 Gbit/s. The size of a page is 1024 bytes. What should the probability of a page fault be so that access time degradation does not exceed 14%?

Consider a disk drive specifications. with the following 16 surfaces, 512 tracks/surface, 512 sectors/ track, 1 KB/sector, rotation speed 3000 rpm. The disk is operated in cycle stealing mode whereby whenever one byte word is ready it is sent to memory; similarly, for writing, the disk interface reads a 4 byte word from the memory in each DMA cycle. Memory cycle time is 40 nsec. The maximum percentage of time that the CPU gets blocked during DMA operation?
A disk contains total 200 tracks and Request Queue contains tracks 80, 160, 41, 136, 22, 18, 192. Apply FCFS and SCAN and find total track movements if head start position is at 50. Compare the results and Discuss which algorithm is better to apply?
Calculate the number of disk tracks traversed using the FCFS algorithms for the series of disk track service requests given as 54,36,21,74,46,35,26,67. At the time the first request arrives in the disk request queue, the read/write head is at track 50, moving toward the outer (lower-numbered)tracks. Draw the graph of the movement. Assume that the disk has 100 tracks from 0 to 99.
On average, a typical page of text holds roughly 2000 characters. Approximately how many pages of Unicode text can a storage media with 1 Gigabyte of free space hold? Show the process of unit conversions and calculation required.
A file system with 300 GByte disk uses a file descriptor with 8 direct block addresses, I indirect block address and 1 doubly indirect block address. The size of each disk block is 128 Bytes and the size of each disk block address is 8 Bytes. The maximum possible file size in this file system will be ?
Consider a single-platter disk with the following parameters: rotation speed: 7200 rpm; number of tracks on one side of platter: 30,000; number of sectors per track: 600; seek time: one ms for every hundred tracks traversed.

Consider a disk pack with a seek time of 4 milliseconds and rotational speed of 10000 rotations per minute (RPM). It has 600 sectors per track and each sector can store 512 bytes of data. Consider a file stored in the disk. The file contains 2000 sectors. Assume that every sector access necessitates a seek, and the average rotational latency for accessing each sector is half of the time for one complete rotation. The total time (in milliseconds) needed to read the entire file is__?
