The capacity of the hard disk is wrong, it is exaggerated, the actual capacity of the hard disk is s

You first look at the folder that is relatively large, and look for it one by one, and you will know that it is the file, and open the hidden file first

If not, it is advisable to back up useful stuff with a hard drive tool such as DM to re-partition the formatted partition

There is no problem, the hard disk has to write some data when it is partitioned, and the actual hard disk is larger than the size of the available hard disk

This is not surprising, the hard disk manufacturer is calculated by 1g = 1000m in the factory, and the computer is calculated by 1g = 1024m, the larger the hard disk, the less it is.

Do you freeze often? Reboot?

If it is, it's a bad sector on the hard drive!!

Did you make a backup with a one-click ghost or something?

Because in the world of computers, the unit conversion is calculated according to 1024, 1024b = 1kb, 1024kb = 1m, 1024m = 1g

However, when the hard disk manufacturer calculates the capacity, the unit conversion is calculated according to 1000. 1000b = 1kb, 1000kb = 1m, 1000m = 1g and so on.

Therefore, the capacity of the nominal 512g solid state is actually 512*1000*1000*1000=.

And the algorithm of the computer, it is displayed.

The nominal 500g solid-state is the only one.

If you are a 1T hard disk, then the conversion from G to T depends on whether it is 1024 or 1000, and the actual capacity is also different.

According to 1024g=1t, then the actual capacity is; According to 1000g = 1t, it is actually 931g

In addition, after installing the system, it will divide the boot partition and the recovery partition, which is invisible when this part of the space is in "This PC". Therefore, the total number of hard disks seen in "This Computer" is one or two gigabytes smaller

Your hard drive is filial piety 500g, nor is it 512g.

This is actually due to the fact that the conversion criteria adopted are different.

The computer world's 1024 = 1K conversion algorithm is the standard of the International Electrotechnical Commission (IEC), and 1000 = 1K is the base system in the metric (SI) unit.

In the IEC standard, there is no such unit as "KB", "MB", and "GB", but units such as "KIB", "MIB", and "Gib", and all units have an extra letter "i" in the middle of the SI standard.

So in reality, it's 1024kib = 1mib and 1024mib = 1gib instead of 1024kb = 1m and 1024m = 1g

The computer world follows the IEC standard, while the manufacturer uses the SI standard.

In official language, the two standards cannot be confused, and units such as "mb" in Qiaoshan manuscripts without "i" are metric units, which must be 1000 decimal system.

Therefore, the hard disk manufacturer uses 512GB and 1000GB computing capacity in metric units, but the computer displays the capacity in IEC units of 476GB and 931GB, resulting in the actual capacity of this hard disk is smaller than the nominal capacity.

The reason for this is that about 20 years ago, the translators who introduced these units were not computer majors, and confused IEC units with "I" with metric units without "I". In our colloquial language, Gib becomes GB

Check if there is a hidden folder,Another possibility is that your backup folder has agreed on the size of the capacity,Although it itself is not large,But there are actually more than 50G to give it priority。

The main reason why the actual capacity of the hard drive is less than its nominal capacity is that manufacturers generally calculate the capacity by 1000K bytes per megabyte, while the BIOS and test software of most motherboards are calculated at 1024K as one megabyte. As a result, there is a difference between the two. The capacity of the hard disk is divided into the physical disk capacity calculated purely by the number of heads, the number of cylinders and other physical parameters, and the actual available space after partitioning, formatting and other operations.

In addition, selecting different working modes (normal, LBA, large) in the CMOS may also cause capacity inconsistencies. So this is just a matter of calculation method, not profiteers.

This is a problem with the hard disk manufacturing process.,For example, 160G,It's impossible to reach 160G capacity.,At most, it's about 140.。。

The theoretical value of the capacity is 1G = 1024MB

But the hard disk manufacturer is 1G = 1000MB

So it will be slightly less.

Don't be surprised.

It's all like that

I've been used to it for a long time.

It is more troublesome, and there are certain requirements for technology, if you are not very confident, it is recommended not to operate.

1.Requires the use of third-party hard drive partitioning software, such as Acronis Disk Director Suite. It's a good idea to back up your important data before using it, just in case.

2.Squeeze out the free space from partitions C and D, then merge 30G with E, and create a new partition (set to F) for the other 5G, after completion, the system will restart, perform partition modification operations, and then you can take the next step after completion.

3.Install the system with XP. The mounting position points to the F drive. Note that after installing XP, win7 will be corrupted, causing win7 to fail to start.

4.Use the win7 installation disk to start the new boot and run the installer, and select the repair win7 startup item.

That's it. Don't look at what I'm saying simply, the first step should be carefully considered. It takes a lot of time, and everything goes smoothly estimated at 1 2 hours.

Please refer to the details below for details on how to use partitioning software.

Hard disk capacity is measured in megabytes (MB), gigabytes (GB). The capacity shown in the computer is often less than the nominal value of the hard disk capacity. This is due to different unit conversion relationships.

In Win7, 1GB is 1024MB, and hard disk manufacturers usually convert it according to 1G 1000MB. So your hard drive capacity is fine. Hope it helps

It's boring to say anything else! I recommend that you copy the data and repartition it directly.

General logic: Software problems can be fixed, if it still doesn't work after partitioning, it is likely that there is a problem with the hard disk firmware or platter.

There may be a disk logic error, select the tool item in the properties of the E disk, click Disk Scan, and let Windows scan the disk.

Because there are too many files in win7, there is a lot of long space.

When it comes to limits, there should be. Nothing is created by an accumulation, but by a combination of substances or materials. As the Dharma says, everything in the world is manifested by the combination of many things.

There is no maximum, only bigger! 2 48 sectors are accessible in LBA mode, but now a new mode has appeared!

It doesn't matter how much the hard drive is sized or how it's transferred.

There's no problem with this, you can pick up as much as you want

No, but a hard drive that is too large to fit the system.

It's not restricted, but it's too big for the system to bring.
