Usually we go to the store to buy a hard drive is going to be found to buy back the actual capacity of the hard disk is smaller than indicated, for example, you bought a 64GB memory card marked,
You may buy back plug to discover not only 59GB of 64GB but look, this is why? You may feel that manufacturers lie to you, in fact, he did not,
He just used your knowledge blind spot it, he indicated that the 64GB using a decimal notation,
Therefore 64GB = 64 * 1000M = 64 * 1000 * 1000kb = 64 * 1000 * 1000 * 1000Byte bytes,
Then transformed using a binary became when the capacity of the unit data, 64 * 1000 * 1000 * 1000/1024/1024/1024, is probably the way of the 59GB,
Hard drive manufacturers not to lie, just because minimum physical hard drive is 512B, the smallest constituent unit of the sector, how many sectors are usually calculated using the hard disk capacity, it will use
Decimal to deal with.
