Is the flash disk capacity missing?

The size of the information stored by a computer, the most basic unit is the byte, a Chinese character is made up of two bytes, and letters and numbers are made up of one byte.

The units of capacity from smallest to largest are: bytes (B), KB, MB, GB, and TB. The relationship between them is:

1tb=1024gb

1gb=1024mb

1mb=1024kb

1KB = 1024 bytes.

Usually people use the simple name of removing the "b" at the end.

The above is the answer given according to the textbook, but the theory and practice are a little different, the hardware, especially the hard disk, the way of conversion is slightly different, both the 1024 in the above formula is replaced by 1000, 24 is negligible. So in reality, when we buy a hard disk, we will find that there is a difference between the actual usable capacity and the nominal one, the actual usable capacity is smaller than the nominal one, and the larger the hard disk, the greater the difference, the U disk manufacturer takes 1000MB as 1GB, and our Windows system takes 1024MB as 1GB, that's it.

So it's normal for your 1G USB flash drive to display 987MB!

The flash disk will eat 2-4m every 256m, which means that your 1g, about 15m less, is normal.

You have to pay attention, flash disk is not a hard disk, it's best not to format it often, hehe, Patriot is not good, it's normal to have 20m less, don't worry.

Buy 1G,There's nothing wrong with that,But we usually press 1000MB is equal to 1G,But the computer recognizes that it is 1024MB is equal to 1G,That's accurate,So there's no problem when you flash the disk,There are some applications here that occupy space,So there's no problem at all when you flash the disk! Got it?

The so-called 1g is a theoretical value.

It is impossible, or almost impossible, to buy a disk that is exactly 1000MB.

Just like the 80G hard drive we bought, it is generally more than 70G

It's all normal.

Nothing strange,

The full 1G should be 1024MB

The capacity is small.

This is because it has to store its own sector information, which will take up some space when letting.

It's normal.,1G is more than 900m at most.,It's okay.。

Because it has to store its own sector information, it is normal for your 1G USB flash drive to display 987MB.

Low the grid or go to the official website of the product ** mass production disturbance tool, mass production once ..If it doesn't work, you may be cheated! Merchants use some software to bracket the USB flash drive, but the actual size is not so big, and it is only a few times to see that the pants are really big and the net loss is small!

The capacity of your hard drive is not lost, you should be a 320g hard drive.

This is related to the principle of disk production, because the block of the disk is 50MB as a unit, so the 1G = 950MB of the hard disk, but the actual operation is 1G = 1024MB, because the large volt is convenient for the operation and simplifies the production process, so the hard disk manufacturers will make it in the ratio of 950 = 1, so that there will be no scattered blocks, thereby reducing the difficulty of production.

Therefore, the capacity of the 320g hard disk will actually be, and according to the different manufacturers of the disk, the excess space on the disk will be created, and the final result is your hard disk.

That's how all hard drives are calculated, and so is my 500g hard drive.
