My computer s hard drive is 160, divided into three areas, but why do the three disks add up to 120?

Generally, the actual amount that can be used for an 80G hard disk is about 72-76G. For example, if a house is 5*5=25 square meters, and you divide it into 3 small rooms (equivalent to C, D, E disks), the board of the open room will always occupy some space, right? So you see that the combined capacity of the CDE disk is only about 72-76g.

Part of the space is equivalent to these boards, so that the ground data of disk D will not get to disk E.

Generally, the capacity conversion of hard disks is 1000=1024. So there's still some gaps in that. Always, it is normal for a so-called 80G hard disk to be usable at 74-78G.

Your actual capacity of 160G is normal at 120, and there is still a portion of the motherboard BIOS reserved.

1. There is also a hidden partition for backing up the system, which takes up a few gigabytes, and you can't see it; Second, when the system was first installed, it was not divided into good areas, and there were several (ten) g that were not divided, ** partition magician, you can recreate it!

See if there is a hidden partition? It is generally used in the factory fashion and recovery system.

Take a look at Disk Management in Computer Management.

No matter how bad it is, it's not as bad as 40g, it's too much. Right-click on my computer-management-disk management and see if there is any of the missing 40g

There should be more than 30 g, you use the partition tool to see if there are any undivided areas.

HP has its own hidden partition used to store your system System Restore This doesn't matter If you want to get it back, just make a system yourself and delete the hidden partition of HP Tips: A normal 160 hard disk should have an actual space between 146-150.

This is quite normal, because the hard disk capacity is calculated as 1g = 1000mb, you can calculate it yourself, no fuss.

Because the manufacturer uses 1000MB for 1GB, and the system uses 1024GB for 1GB. So don't fret!

Ha! It's normal, because the capacity of hard disks is calculated by manufacturers when they are produced by 1MB=1000KB, while the computer is calculated by 1MB=1024KB, which means that the 160G that the manufacturer tells you is actually not that big, which is the rule of the industry; In addition, after you partition the hard disk, the computer will automatically allocate a part of the space to store your partition information, and the more partitions it takes, the more space it occupies, but you can rest assured that the partition information occupies a relatively small space, and it will not have any impact on the user.

The characteristics of the product itself, which involves a difference in the conversion of capacity and size, we know that the capacity is 1G 1024M, and the hard disk manufacturer is made according to 1G 1000M, so now your hard disk is 160G, the actual size should be 160*1000 1024=156G, now you say only 140G, indicating that 16G is indeed lost, you can go to the control panel, management tools, computer management, disk management, Check in to see if your partition has any undivided, and the data in it should be very real.

This is the difference between the algorithm between the hardware vendor and the software vendor, the hardware vendor uses the integer algorithm, that is, 1g=1000m, 1m=1000k, 1k=1000b

The software vendor uses the standard algorithm, 1g=1024m, 1m=1024k, 1k=1024b

In addition, the partition will occupy a part of the hard disk capacity, so the actual 160G disk partition is only 140G.

For hard drive capacity, there are two algorithms:

One is the calculation method of hard disk manufacturers, in their opinion, 1M = 1000KB, the same way, 1G = 1000M (in fact, this algorithm is generally used to calculate the flow during communication data transmission).

The second is the calculation method of the computing system software, which thinks that 1m = 1024kb and 1g = 1024m (this is the correct algorithm).

In addition, there are hidden partitions, so it is normal for the hard disk marked with 160g to become 140g under the software.

The reason for this is that the system calculation method is different from the calculation method of the hard disk manufacturer, the system is 1G=1024M, 1M=1024K, and the disk manufacturer is 1G=1000M, 1M=1000K, the calculation method is different from the system, and the detection in the BIOS is the same as that marked by the manufacturer.

No need to look for it, this is normal.

Hard disk manufacturers use 1000 as the base system.

The system is based on 1024.

So it's normal for the hard drive to have less capacity than the nominal one.

If the system is installed by the dealer for you, then the 20G may be used to install the system backup or something.

Even the book is,160g,There are about 20g for one-click recovery。

No, configuration files still take up space.

See if there are any hidden partitions?It's clear upstairs that it takes up a little space, so don't worry about this, check it carefully.

By the way, tell me about your model so that everyone can get to know it.

The brand's compatible or book?

It could be the time of partitioning. 20 gFind out only by repartitioning.

Yours is not a Lenovo brand machine,Lenovo will automatically divide out some space for backup,No, you use PQ (partition magician) to see if there is still space in**!

It should be about 147g to be normal, I have calculated, the display capacity should be about 92 of the identified capacity to be normal.

160g is theoretical. It's actually 160 1000 1024 g

It should be tested with an optimization master.

Turn off System Restore and take a look.

Originally, the nominal size of the hard disk is not enough, the nominal k, g, and t are carried out according to 1000 round, while the display on the computer is generally based on 1024 round. In addition, Lenovo's computers have made a hidden partition, which is used for system backup, which also occupies a part of the capacity.

1g = 1000m = 1000 * 1000b written on the label

The calculation in the computer is 1g=1024m=1024*1024b.

In this way, 160G is equivalent to about 150G in the computer, and you go to the "Control Panel" - Management Tools - Computer Management". Select "Disk Management" on the right side of the pop-up computer management window, and on the left you can see the size of each disk, including the hidden partition, which adds up to how much.

No, 160, it can't be 160, what is shown and what is actually not necessarily the same!Mine is also Lenovo, 160 shows 150!

Brand machines generally have a hidden partition, which is normal.

After partitioning, some partition files will be generated, which will take up a part of the storage space. Moreover, the algorithm of the storage space of the hard disk is different from that of bytes, and it is calculated in terms of 1000m=1g, so there will be discrepancies. There is a difference between the theoretical value of 128g is 1024x128m and the actual value is 1000x128m.

The manufacturer said that 1g = 1000mWe are talking about 1g = 1024m

The manufacturer's algorithm problem is 1000m=1g, and the system is 1024m=1g

There are already four partitions, a primary partition, and 3 logical expansion zones, where the first partition is the same as the second partition, no problem by 110schoolx

Impossible, it must be the landlord who is mistaken, this is indeed 4 districts, an active partition, an extended partition, there are 3 logical volumes in the logical partition, and there is no such thing as a partition display disorder.

And the landlord can calculate the total capacity by himself, and the capacity of these 4 areas adds up to exactly the actual capacity of the 500G hard disk, about 460G.

If you don't need as many logical partitions, delete the first two logical partitions and create a primary partition. The primary partition has a lot of boot functions, while the logical partition is difficult to adjust and does not have the boot function (that is, various bootloaders cannot be installed), so it is recommended to divide the main partition into multiple parts. At present, it is more painful to merge logical partitions, because the PBR of logical partitions is not continuous, and the primary partition can definitely be merged.

The values of the four zones together are exactly equal to the fact that you do have 4 zones. One primary partition and three extended partitions.

If you adopt it in time, you will ** to 5 wealth points.

This is the right person.,Mine is three districts.,But to reinstall the system.,Mine is when the system is installed.,Partitions,My system is installed by myself.,As long as you have a little computer knowledge.,Then,How many districts you can divide in.,Five partitions,Two,It's okay.,Whatever you set up.,You can also each partition.,How many g can be divided.,Not enough I think you'd better not toss.,Otherwise,If you want to install the system.,Redistribute the area.,The information inside will be gone., Now it's natural that way.

Like this is troublesome.,Go directly between the systems.,The next partition tool 1 minute fast partition,I used to too.,Little by little,Now,Directly divide.。

Divide your hard disk into two disks, C disk needs 60G, D disk is also 60G, it is best to add a mechanical 500G hard disk, then the solid state does not need to be partitioned, no matter the system or the game is guaranteed to slip and slip.

d、E disk tidying up,It's best to sort out a little more 40g to play,Why is such a small disk not hanging a machine? 120g you have a little more partitions, 120g is good for two zones. The configuration requirements have met the requirements of eating chicken, and there is no problem with 1080 low resolution and smooth special effects.

Separate a part of D and E into C drive, there is software on the Internet, no need to repartition.

Hello, which partition method do you use?

Upstairs, you probably didn't get the rest in.

Unpartitioned is not displayed.

First put all the things you want to move the disk into your computer, and then my computer - disk management - find those areas, right-click to delete the three logical drives, and then right-click to create a new logical drive, there is a place to change the size to the maximum, you can change the disk.

Only backup first, and then repartition, the data on the C drive is installed when the system is reinstalled.

If you want to merge partitions without losing things, it's unrealistic, you can only test things out first, and you can test them into the hard disk of your computer first. Then right-click on my computer, open Disk Management, delete a few partitions of the portable hard drive, rebuild a new area, and copy things back.
