Apple iMac1TB hard drive system occupies 500G What s going on

As Moonbarking replied, this is due to the difference in the way hard drive manufacturers and Microsoft (and you must be using Windows).

It's just a matter of data presentation, and there are no actual physical problems, let alone actual use, so you don't need to deal with it at all. Because everyone is like this, I will buy so much less 1TB hard drive, and others will buy so much less.

In addition, I would like to give you a suggestion, the hard disk is large, it is best not to partition it more, because every time you divide a zone, there will be an extra hard disk partition table that you can't see, and it will occupy the hard disk space. I used to divide my hard drive (also 1TB) into a lot of areas, wasting a lot of space, and then re-dividing the area. My current partition is:

C disk is the system installation disk, D disk is the software installation disk and document storage disk (including **, ** and work documents), E disk is the game installation disk, F disk is the movie storage disk, and there is a 250G slave disk for **.

If you use a 1TB hard disk as a slave disk, and a 500G hard disk as the main disk, it is recommended that you partition it like this to save space: C disk 40G as a system installation disk (whether it is installed XP system or Win7 system is enough), D disk 210G as a software installation disk and personal document storage disk, and the remaining part of the 500G hard disk is used as an E disk to install games. It is recommended that the 1000G hard disk be divided into 2 areas (F drive and G drive), which is convenient for use.

A little more nonsense, don't mind.

Turn off the Time Machine and restart the computer to try it.

Because Time Machine has a local snapshot feature, it may take up some.

About Native Storage System Percentage is also so much?

Press Command+R when booting up the computer to restore the Mac OS X system.

Your configuration will be very stuck.,The current emulator is not perfect.,At least 10G,It is recommended that non-Apple computers are best not to install Mac systems (ordinary people are not used to it.,My Apple computers rarely use it)

This is true for every drive, and the actual capacity is less than the nominal capacity.

The window and iMac systems read the disk capacity in different ways.

The carry is different, some are calculated according to 1000m=1g, and some are calculated according to 1024m=1g.

First, Fusion

Drive is actually a combination of a 1TB or 3TB HDD and a 128GB Samsung 830 SSD. As we all know, many ultrabooks also use hybrid hard drives, but most of the capacity of the SSD part is only between 8GB and 32GB, which cannot be used as a system disk, but can only be used as a data cache space, Fusion

1. First of all, on the home page of the computer, click on the Apple in the upper left corner and select "About This Mac" inside.

2. On the pop-up page, select "Storage space".

3. You can roughly see the memory usage and the remaining amount, but it is not detailed enough, click "Manage" to manage the memory in detail.

4. In the list bar on the left, you can see the memory usage list (except for the system files, the bottom gray indicates that it cannot be cleaned, and the rest can be cleaned).

5. Click on the folder on the left column of Documents.

6. Select the specific file on the right to delete.

7. Click Delete File, and a pop-up box will appear to confirm again. Delete unwanted files and your system memory won't take up too much.

1. The default installation of Mac OS X requires about 22G space, but if you delete the printer drivers and language packs that you don't need inside, you only need about 15G space. The size of the iLife kit is not included here.

2. If it does not affect the use, the size of the stay depends on personal preference. Because Mac OS is based on the UNIX kernel, it will not produce too many file fragments in use, and even if only 1G to 2G space is left, frequent disk permission verification can also ensure the speed of the system.

The system starts, the system comes with the function of cleaning up storage space, click the apple icon in the upper left corner, about this machine, and clean up the storage space directly.

What to do if the Apple X system occupies too much memory.

15G-20G or so, but you'd better allocate 60G, because the Apple system is not divided into C disk and D disk like Windows, and all the software will be installed in the root directory, that is to say, it will occupy less than 20G after the system is just installed, but with the passage of time, more programs will be installed, making the system disk bigger and bigger.
