In the past, disks in IBM PC are addressed by 24-bit CHS address, where 10bits for cylinders(C), 8 bits for disk heads(H), 6 bits for sectors(S). Assuming the capacity of a sector is 512 bytes. Consider the following disk I/O request sequence (assume the requests are represented by CHS address by hexadecimal, and the disk has the maximum capacity with above addressing) 1AC320, A2F5BC, 7A182D, EF6714, FOD76A, COF1D1, FFF236 (a) What is the largest capacity of this disk? (b) What is the seek distance (in cylinders) when using the following disk scheduling algorithms? Note that, the drive is currently serving a request at cylinder 50. (Please answer with a decimal number.) (i) SSTF (ii) C-LOOK (Start direction: moving from left to right)
