Windows and the Case of the Missing Hard Drive Space Advertised Capacity versus Reality

You may have noticed in “My Computer” that the laptop batteries amount of disk space available to Windows is less than what you know your hard drive capacity is. For example, if you know you have a 160GB hard buy laptop battery drive, Windows may report only 149GB of usable space. Why is this?

Computers are built off ones and zeros – the binary language. When making laptop battery calculations based on computers Dell Inspiron 1520 Battery, everything is calculated in Base 2. As a human, we’re used to counting in Base 10. This is part of the problem – the cheap laptop batteries other being that manufacturers make faulty assumptions to make it “easier” on us humans.

Manufacturers make the assumption that one Gigabyte replacement laptop batteries of hard drive space is 1,000 samsung laptop adapters,000,000 bytes , but in Base 2, one Gigabyte is 1 dell laptop adapters,073,741,824 bytes. Thus for every Gigabyte the manufacturer laptop battery shop advertises, the real capacity is about 73,000,000 bytes or 73MB less.

In our example, we’ve got a 160GB hard drive. If we multiply 160GB by 73MB cheap laptop battery (160x.073) we’ll get 11.6GB. Take 160GB minus 11.6GB and you have roughly 149GB – the size of the hard drive shown in XP (Figure 1). Unfortunately, there laptop battery charger isn’t much you can do about this other than being aware of this “trickery” and purchasing a bigger hard drive if you need it.
