Problem 1

Information Given:

i) A magnetic Hard Disk is labeled Argon

ii) It has 8 plates

iii) Each plate is able to write on both sides.

ii) Each sides have 300 sectors

iii) Each sides have 220 tracks

iv) 1 cluster = 2 sector-track

v) File AngelinaJolie.doc = 2,690,800 bytes

vi) File WithoutYou.mp3 = 376,000 bytes

Calculate:

a) The number of sector-track on one plate?

b) The number of sector-track on entire hard disk?

c) How much can be stored on one plate?

d) How much can be stored on entire hard disk ?

e) How many cluster on one plate?

f) How many cluster on entire hard disk?

g) What is the total track in the entire hard disk?

h) How many cylinders in hard disk ?

i) How many sector-track in 1 (one ) cylinder ?

j) How many clusters to save AngelinaJolie.doc?

k) How many clusters to save WithoutYou.mp3?

l) What is the percentage used by Hard Disk Aragon when saving AngelinaJolie.doc and WithoutYou.mp3 together?

m) What is the percentage left in the Hard Disk Aragon after saving the 2 files?

Problem 2

Information Given:

iv) A magnetic Hard Disk is labeled BradPitt

v) It has 6 plates

vi) The top and bottom surface of this hard disk are not allowed to write.

vii) Each sides have 190 sectors

viii) Each sides have 140 tracks

ix) 1 cluster = 2 sector track

x) File SuriCruise.doc = 4,510,800 bytes

xi) File Dukacita.mp3 = 480,000 bytes

Calculate:

n) The number of sector-track on one plate?

o) The number of sector-track on entire hard disk?

p) How much can be stored on one plate?

q) How much can be stored on entire hard disk ?

r) How many cluster on one plate?

s) How many cluster on entire hard disk?

t) What is the total track in the entire hard disk?

u) How many cylinders in hard disk ?

v) How many sector-track in 1 (one ) cylinder ?

w) How many clusters to save SuriCruise.doc?

x) How many clusters to save Dukacita.mp3?

y) What is the percentage used by Hard Disk BradPitt when saving files SuriCruise.doc and Dukacita.mp3 together?

z) What is the percentage left in the Hard Disk BradPitt after saving the 2 files?
