60G hard disk is less than 4G after reinstalling the system, why ???? 20

1GB recognized by digital products such as computers and 1GB in industry. Computers and other digital products are strictly in accordance with the binary code to identify the capacity. Therefore, the relationship between KB, MB and GB is 1024 times higher for digital product recognition.

The relationship between KB, MB and GB is 1,000 times higher in industry. In other words, the industrial capacity is smaller than the capacity recognized by digital products such as computers. Coupled with the errors in actual production, there will be less capacity for digital products such as computers to identify.

This is true for other digital storage devices, such as computer hard disk capacity.

Do the math: 80g * 1000 (industry standard) 1024 (digital standard) = actual hard disk capacity).

Another part is your virtual cache, and the page files also take up a lot of space, which is hidden and generally not visible.

This is normal for a 60G hard drive, and the actual space should be more than 55G.

None of the hard disk space is the nominal size.

40 is about 37

60 for 5580 for 74

120 for 114

It's taken up by the garbage.

is normal and can be calculated like this:

This phenomenon occurs on the computer, which is caused by a problem with the hard disk, and you can try to fix it with the following steps.

1. Connect a USB flash drive to the computer, then restart the computer, when the computer restarts to the BIOS self-test screen, press the DEL key (some notebooks press the F2 key) to enter the BIOS setting interface, in the advanced options, turn off the 32-bit addressing mode of the hard disk (32bit I O in the figure below), and then press the F10 key to save the settings and restart.

2. After the computer restarts, enter the quick boot menu (the common situation is to press the ESC, F11, F12 buttons), and select to boot from the USB flash drive.

3. The computer boots from the U disk and enters the PE environment in the U disk, at this time, you can use the DiskGen software in the PE environment to check whether the total capacity of the hard disk is normal (the actual capacity of the 80G hard disk is generally about 75G, and the capacity of the 80G hard disk in the figure below is. If the capacity is within the normal range, you can use it to repartition the hard disk;

If the total capacity of the hard disk is still 32G, you may need professional software and tools to repair the hard disk (such as PC3K, MRT and other tools), generally in this case, it will be more convenient to replace a hard disk for the notebook.

5. After the system installation is completed, the computer can be used normally.

This can be a lot, and the easiest way to fix it is as follows.

Go in PE or check the disk management tool to see the hard disk usage, if it is normal, the hard disk itself can be used so big, the reason is not much.

If it is not normal, it means that the installation system is incorrect.

In fact, everyone understands that they can install the system, and it is recommended to find someone else to install it if they can't install it.

It's a problem with the system. All 32-bit systems,Whether it's XP or Win7,Can't fully use 4G memory,The display is about,The display of each computer is slightly different,The specific reason is not very clear,It may be a problem with the shared video memory used by the integrated graphics card,The actual use is also,This is unsolvable,It has nothing to do with reinstallation。 The 64-bit system of win7 is supported, and it should be able to recognize and use 4G memory normally, and the system used for the server (such as win2003) is completely usable.

There are a lot of people on the Internet who are looking for cracked patches,After using it, you can make the system recognize 4G memory,My suggestion is not to use it,It just makes the system display4G,It's not really that the system can use 4G,It can be proved from running a very memory-consuming program,Such as the rendering function of design software CAD、Photoshop、Large image software, etc.,Use it will make the system unstable。 It can be detected with various tools and software, such as CPU Z, AIDA64, etc., all of which can correctly display the amount of memory you have.

1.The computer conversion is different (what 1GB=1024MB I completely fainted from this, and I didn't learn math well) -- caused.

2.For example, there are 1,000 households on a street, but there are only 800 house numbers, so there are still 200 households that don't get house numbers, but these 200 households don't disappear.

So: the money spent is not in vain, and it still uses 4GB of memory.

XP's operating system, right? 4G memory is not supported, and the display looks like this. Install a win7 display and it's normal.。

Hello, the system should take up a little memory, so, it will definitely be reduced, don't worry.

You can choose the easy-boot USB flash drive boot maker to reinstall the system. The installation steps are as follows:

1. First of all, make the U disk into an easy-start U disk to start, restart the computer and wait for the boot screen to appear, press the startup shortcut key, select the U disk to start to enter the easy-start main menu, select the "Enter Win8PE environment installation system" option, and press the Enter key to confirm.

2. Enter the win8pe system, the installation tool will pop up by itself, click "browse" to select and save it to the system image file in the U disk.

3. Wait for the easy-start PE installation tool to automatically load the system image package installation file, just select the installation disk location, and then click the "OK" button. At this time, click the "OK" button directly in the pop-up prompt window. Then the installation tool starts working, please wait a few minutes.

4. After completion, a prompt will pop up to restart the computer, click the "Yes (Y)" button.

5. At this time, you can unplug the U disk, restart the system to start the installation, we don't need to operate, wait for the installation to be completed, and finally restart it once before entering the system desktop.

1. The general file system uses FAT32 formatted hard disk or U disk, and there is a size limit when copying files, and under normal circumstances, it is not possible to copy files larger than 4G at one time.

2. If you want to copy files larger than 4G at one time, you need to format it with NTFS or EXFat file system, the hard disk is recommended to go directly to NTFS format, and the U disk is recommended to use EXFat format, but you can also use NTFS format.

3. The formatting method is as follows:

Turn on the computer, right-click on the drive letter you want to format, select Format A, after the format dialog box pops up, left-click on the drop-down button of the file system, select NTFS or Exfat, and start.

Yes, but it is recommended to back up important data.
