Please answer as soon as possible

seek time = 4ms/track

search time= 1.7ms/sector  

T/S     Seek time     Search time            Total  

3,0   start

2,5   1*4=4              5*1.7= 8.5        4+8.5+0.5 = 13

1,2   1*4=4              2*1.7=3.4         4+ 3.4+0.5  =7.9

1,0   0                      0                   0+0+0.5=0.5

2,3    1*4=4            3*1.7= 5.1        4+ 5.1+0.5=9.6

2,4     0                 4*1.7= 6.8        0+6.8+0.5=7.3

1,0     1*4=4                 0               4+0+0.5=4.5  

Total time= 13+7.9+0.5+ 9.6+7.3+4.5=42.8 ms

Remember Data transfer is 0.5 for all.

Explanation:

The mean time it takes from one track to another is seek time. hence = track difference * seek time per track

And similarly search time = no. of sectors * search time per sector

And this we have used to calculate above.

the only way i would see could be an autoclicker type software. but that is very time consuming.
