Each side, or surface, of one hard drive platter is called a head. Windows Vista technology that supports a hybrid drive is called ready drive.
head
Each platter on a hard drive has 2 heads.Every Additional Platter you can multiply x2Example:1 Platter x 2 = 2 Heads2 Platters x 2 = 4 Heads3 Platters x 2 = 6 Heads4 Platters x 2 = 8 Heads5 Platters x 2 = 10 HeadsETC...At least until some new hard drive Architecture comes into place.
AN 80GB drive will have about 78,125,000 sectors on each side.
surface area of cube=6*side*side =6*7.2*7.2
Each side measures 15. Divide the known surface area by 6... this gives you the area of one side. The square root of the area of one side will give you the length of each side.

The surface area is quadrupled.
this is incorrect -- quick example.. 2"x2"x2" cube -- will have a surface area on each side of 4"sq (2x2=4) --- now make that 4"x4"x4" -- this cube will have a surface area on each side of 16"sq (4x4=16)
Surface area is 600 cm2
There isn't a true standard serving platter size. The size of the platter depends on the shape of the platter. A normal rectangular serving tray can range in size from 14x10 inches to 18x12 inches.
It will be a quarter of what it was.
