The capacity of the USB flash drive does not match the actual size, why is the size of the USB flash

You should find a mass production tool for mass production of this phenomenon, and it should be fine. The capacity of the USB flash drive after mass production is displayed back to the actual usable capacity.

From the Internet** a chipgenius (chip wizard) plugged into the U disk, open the chipgenius, the software will automatically detect the main control chip of the U disk, and the mass production tool of the corresponding main control chip will be provided below. How to mass production, the methods of various main control chips are different, this depends on how the chip manufacturer designs, but as long as it is not too obscure chips, you can find a lot of tutorials on the Internet, so you don't have to worry too much.

Don't be greedy to buy copycat disks cheaply when you buy a USB disk, most of them are expanded, that is, there was only 2G originally, and you can see 16G after expansion, in fact, it can't be used at all.

First, use chipeasy to check whether your USB flash drive is an expansion USB flash drive.

If it is, it is a fake USB drive bought by a profiteer.

Search for mass production tools by chip model in the chip worry-free to restore the original capacity...

Because the specifications of each manufacturer are different, it was originally stipulated that 1G is 1024MB, but some manufacturers produce products that are 1G is 1000MB, so the actual space is smaller than the displayed space.

Then your USB flash drive must be damaged, restart the computer, format it again, and see if there is any problem.

Introducing your detection software, mydisktest

Normally, the actual unit of measurement of capacity is 1024KB=1MB, and now the unit of measurement of Chinese manufacturers is 1000KB=1MB, which is different from the theoretical base system, so the capacity of the USB flash drive we bought is different from the actual capacity.

1. Not only the U disk is different, the memory card, and the hard disk are bent side by side, the capacity is different from what they say, this is the problem, for example, an 80G hard disk His actual capacity is generally only 76G-78G, and a 160G hard disk is generally only 143G.

2. If you buy it abroad, like the United States, it is generally greater than 8G, and generally the capacity of their target 8G is about the actual capacity you use, because the unit of measurement of our leakage is different.

3. A part of the capacity is hidden, and the masking grip is set up so that the space will not be lost when it is repaired in the future.

Normal, the actual unit of measurement for capacity is 1024KB=1MB.

But now the unit of measurement for manufacturers in China is 1000KB=1MB.

It is different from the theoretical base system, so there is a difference between the capacity of the USB flash drive we bought and the actual capacity.

Not only the U disk is different, the memory card, and the hard disk are all such a capacity is different from what they say, this is the problem, for example, an 80G hard disk his actual capacity is generally only 76G-78G, and a 160G hard disk is generally only 143G.

If you buy it abroad, like the United States, it is generally greater than 8G, and generally the capacity of their target 8G is about the actual capacity you use, because our units of measurement are different.

Part of the capacity is hidden, so that if it is broken and repaired, it will not lose space.

The conversion standard for computers is 1024k 1m, while the manufacturer's conversion standard is 1000k 1m. Of course, this layer alone is not enough, there is another layer of 1000B 1K for manufacturers, and 1024B 1K for computers, so the gap is getting bigger and bigger.

Because what we see on the computer is 1024k as 1m. For the convenience of calculation, the manufacturer uses 1000k as 1m, so it will be relatively small.
