I have bought a WD 1TB hard drive for saving my data. And many people also suggest that I should partition it into three or four. But, I don’t know why and how. Do I need special software?
i don't know why anyone would put several partitions on a data only HD. some folks like to use one smaller partion for windows only and have another partion for just data; makes creating a back up image easier, that understand but, putting several partitions on a HD will not magically make it faster.
i'd really recommend doing the steps ubrales posted for a single partion.
