My computer hard drive is 80G, divided into 4 disks, each is 18 6G, where is the remaining 5 6G

It's not like this, it may be that your computer has done a one-click restore, you need to grid a hidden partition, this partition is usually invisible to you, he is used to install the system program in your C drive, that is to say, when you use one-click restore, the system uses the backup system in the hidden partition to overwrite your C drive.

This is the capacity calculation method of the system, the calculation method for the manufacturer, the different 1KB = 1024B 1MB = 1024KB 1GB = 1024MB The manufacturer seems to use B to calculate.

I bought 80g, but it's actually only 80000000kb! When you think about it, it's about the same.

Factory is decimal.

1000 bytes = 1 KB

1000kb=1mb

1000mb=1gb

1000gb=1tb

The computer is pressed 1024 bytes = 1kb

1024kb=1mb

1024mb=1gb

1024gb=1tb

80gb*1000*1000*1000/1024/1024/1024=

It's like this, the so-called 40 80g 1g sold outside is actually not enough

Because the manufacturer calculates the advance rate between k m g in order to facilitate the production, it is not 1024 as known

This is a normal phenomenon, the normal partition is smaller than the capacity of the annotation, because the algorithm is different, the normal annotation should be 1g=1024m, while the computer usually uses 1000m as 1g. That's why this missing part is missing.

This is a very normal situation.

In fact, if you buy a 120G SSD, the real usable space is only 10 G, this is a historical problem, and the calculation method used by the hard disk manufacturer when producing is different from the calculation method used by the operating system, one is to use 1000 as the unit of measurement, and the other is to use 1024 as the unit of measurement, therefore, there will be a huge difference.

It's the same for partitions, it's normal to only show 58 or 59 in 60g.

If it's really uncomfortable to watch, or you just want to display 60g, then you can use some partitioning tools to count the approximate value, just fill in this value in the partitioning process, generally speaking, 60 points are displayed, 60 sentences need to be entered more than 61 points.

When you partition, it's divided according to the integer, not according to the actual data, the base system of the computer is 1024 and not 1000 as we say, so there will be more or less differences, so as long as the large number is about the same.

This is not called a missing part, but the NTFS partition is called differently, for example, your hard disk is a 500G hard disk, if you use NTFS format to only divide an area, you will find that the actual size of the hard disk is only about 465G, where did it go? In fact, the computer memory conversion byte is 1:1024, unlike the decimal method that we often learn mathematics, the extra 24 bytes are what you call the missing part, in fact, that part of the memory is in your machine, but the base system is different.

Friends, professional home appliance computer repairers tell you that you don't have to worry about it! The win system is like that, because it's not an integer calculation! For example, we often talk about 1MB capacity, but it's actually 1024KB, if you want to divide 60GB, you can 61200MB or 61GB, if you don't understand, you can ask me.
