*Slaps forehead* HAHAHA! Wow! I can't believe people even write this stuff. Even if you don't understand how a hard drive works, at least you can understand simple physics and that you can't create material from nothing. Where did you find this?
On Yahoo Answers. People ask way too dumb questions than we think.

Hmm . . . This seems to be backwards.
Initially, each bit on a hard drive is set to 0. As you copy data to the drive, the drive itself should decrease in weight. This is because 1 bits take up less area than 0 bits, and, hence, weigh less.To verify this, just measure the circumference of a 0 and the length of a 1. The 0 is about 1/3 longer; therefore, it weights about 1/3 more. Instead of gigabits of 0 bits, over time your hard drive will come to contain a mixture of 0 and 1 bits, decreasing its weight.
The most common cause of weight gain on devices with hard drives is due to the rotational inertial of the drives. As the bearings wear in the drive's spindles, they tend to spin faster, and the additonal centrifugal force causes weight gain, especially on the outer edges of the platters. To alleviate this problem, you merely have to make the drives spin in the opposite direction, forcing the bits to spin in the opposite direction also. This is accomplished by reversing the polarity of the electrical plug that goes into the wall socket.
Good luck.
