Description: consider a hard disk with the following specifications 35in in diameter 10 platters and 2 surfaces per platter capacity 10gb number of cylinders 256 suppose the inner 15 inch diameter is not 08986

Consider a hard disk with the following specifications. 3.5in in diameter 10 platters, and 2 surfaces per platter Capacity: 10GB Number of cylinders: 256 Suppose the inner 1.5-inch diameter is not used for data. Consider the following two options. Option A: Each track has the same number of sectors. Option B: The number of sectors in the innermost track is 50% of the average number of sectors per track, and the number of sectors in the outermost track is 200% of the average number of sectors per track.

00:01 Hello students, so let's go through each of the question one by one.

00:04 Capacity of the track in the byte is equal to 50 sector per track into 512 byte.

00:09 So here the total sector will be by multiplying 50 into 512.

00:14 So we will get 25600.

00:18 So here bytes per track.

00:20 So here these are the total 25600 bytes per track.

00:24 Now capacity of the surface.

00:27 So here 25600 bytes per track into 50 tracks divided by surface.

00:33 So it is 128000 divided by 25600 per track.

00:43 So it will give us the value 12800 bytes per surface after calculation.

00:49 Now capacity of the disk.

00:51 Since there are five double -sided pattern, the total capacity of the disk will be this one.

00:57 So here this factor multiplied by 2 multiplied by 5 platters.

01:03 So after calculating these, it will increase 10.

01:07 So here 256 after this into 10 raised to power 5 bytes.

01:12 Now number of the cylinder.

01:13 Since there are 2000 tracks per surface and 5 platters, the total number of the cylinders can be calculated as 2000 track per surfaces, 2 surfaces into 5 platters.

01:26 So here 20000 cylinders, 2000 tracks per surface into 2 surfaces into 5 patterns.

01:34 Here 20000 cylinders...
