Regarding the disk size, what should I do if the free space of the disk does not match the real size

Apparently 160g.

There are physical and logical algorithms for the size of the disk.

Physically, 1g = 1024m

Logically, 1g = 1000m

How many g we weigh is actually a logical name, also known as a commercial name.

Therefore, from the perspective of physical acquisition, the 160G hard disk is not as much as the 160G hard disk.

1. It's not an integer normal, because the disk itself has its own system information, which will take up a certain amount of space;

2. Your hard drive is nearly 160g, which may be the advantage you have taken advantage of 80.

If you're not mistaken, it's probably 160g, and 160g is about 149g's actual space.

They're right, but I doubt you have two hard drives? Two of the 80's? If not, all I can say is congratulations on your luck!

How hungry your hard drive is.

If it's 150GB or 160, that's normal.

This is because the system will take up a portion of the hard disk space, but it won't be too large.

I don't know exactly what it is used for.

But my classmates said that it was attrition, which meant that the part was invisible. Your drive size is actually 150 or 160 (but only if your drive is 150 or 160 in the first place).

But if it's 80 as you say, it might be that you have two hard drives, or you really can't say it.

The discrepancy between the free disk space and the real size is caused by a setting error, and the solution is as follows:

1. Click Start in the lower left corner of the computer to pop up the submenu.

2. Select "Run" and the run window will pop up.

3. Type "regedit" enter on the page to open the registry.

4. Locate the hkey classes root drive item.

5. Find "tileinfo" in the list on the right, and double-click to open the window of the string.

6. Modify the numerical data to "prop:*; Click OK to save.

7. After the numerical data is modified, restart the computer to take effect and the settings will solve the problem.

The reason why the two drive letters are displayed is because someone has partitioned the hard drive; After partitioning, a physical disk is divided into multiple logical disks. Mascot cover.

Here's how to merge:

1. Right-click on the drive letter you don't need == to delete the volume, and delete the disk partitions that you don't need;

2. Then right-click == on the remaining drive letter to expand the volume, and then go all the way to the next step to add the partition you just deleted to the current partition.

To put it simply, the storage size of the disk is determined by the number of disks, the number of unit storage density, the number of heads, the number of tracks, the cylinder, and the sector The capacity of the hard disk = the number of cylinders * the number of heads * the number of sectors * 512b

The most basic component of a hard drive is a magnetic coated platter made of hard metal material, and the number of platters varies depending on the capacity of the hard drive. Each platter has two sides and can record information. The platter is divided into many sectors, each of which is called a sector, and each sector can store 128 2 to the nth power (n = byte information.

In DOS, each sector is 128 2 to the 2nd power = 512 bytes, the platter surface is centered on the center of the platter, and concentric circles of different radii are called tracks. A hard disk is usually made up of a set of overlapping platters, each of which is divided into an equal number of tracks and numbered from the "0" on the outer edge, with tracks of the same number forming a cylinder called the cylinder of the disk. The number of cylinders on a disk is equal to the number of tracks on a disk.

Since each disc has its own head, the number of disc faces is equal to the total number of heads. The so-called CHS of the hard disk, that is, cylinder (cylinder), head (head), sector (sector), as long as you know the number of CHS of the hard disk, you can determine the capacity of the hard disk, the capacity of the hard disk = the number of cylinders * the number of heads * the number of sectors * 512b.

Files are of course stored as digit 0 or 1 data, and after reading the data, the CPU parses the data through processing restore and determines how to manipulate the files

1. Hard disk capacity:

The factors that affect the capacity of a hard disk are the capacity of a single disk and the number of discs. Many people find that the capacity displayed in the computer is often smaller than the nominal value of the hard disk capacity, which is due to different unit conversion relationships. We know that in computers, 1GB = 1024MB, and hard disk manufacturers usually convert according to 1GB = 1000MB.

2. Flash disk (U disk or CF card, etc.) capacity.

The smaller the chip manufacturing process, the more electronic microdevices such as transistors are integrated into the chip in a fixed area, so the larger the capacity, and the power consumption will be reduced. To put it simply, you can write on a 2cm square piece of paper, at most, others use a magnifying glass, the larger the magnification, the more words will be written, but the paper itself does not change size.

3. Comparison: flash disk and hard disk ratio, the manufacturing process of hard disk is different, the record of hard disk is magnetic, it is mechanical, the ROM chip in the U disk is microelectronic technology, the two ways are different, although the ROM chip is only as big as a fingernail, but, the smaller the chip, the larger its capacity, unless there is a fundamental change, at present, if you want to change and break through the upper limit of the capacity of the ROM chip, it must be realized from nanotechnology!
