Does the U disk display the actual capacity after the low bar?

If there is a big change in the space after the low grid, then congratulations! Yes, the lower bar shows the actual capacity.

If there is not much change, you can copy some large files into it, preferably about the same size as your USB flash drive, and see the speed and the final copy amount! If there are problems, hehe, it is an absolute fake!! Either that's broken ......

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.

Prepare materials: the USB flash drive to be checked, a computer with 360 Guardian installed1, first connect the USB flash drive to the computer, click to open the 3602 in the computer, enter the 360, and click "More" in the main interface.

4. Under the Utility Widget option, we find and move the mouse to the position of the "USB flash drive authenticator".

5. Then click the button to start testing the USB flash drive. Click to start identifying!

6. Finalize the renderings. (The picture below is a shrunken USB flash drive.) ）

1. After depositing **, open each ** and take a look. ** within the actual capacity can be displayed, and ** beyond the actual capacity will not be displayed. If it can be opened all-in, it is a USB flash drive with nominal capacity; If you can't open it all, calculate the capacity that can be opened**, and you can know how large the capacity of the USB flash drive is.

2. The stored file capacity is more than half of the nominal value of the USB flash drive. Less than half of them cannot detect the authenticity of the fake; By nominal value, time-consuming. Especially for large-capacity USB flash drives, it can save a lot of time.

3. If when opening the file, you find that the name of the folder or file has become a messy symbol, and some USB flash drives may appear above when inserting the computer again, it means that the system is unstable, and the upgraded version is certain.

4. The stored file should be a ** file. A ** occupies a few MB, and the larger text material is only a few KB, which can save many operations and save time.

5. If you can't delete the ** file that can't be opened, you can only delete the file by formatting, which also proves that it is an upgraded version of the U disk.

After you plug in the computer, click on My Computer, a mobile disk will appear, you can right-click to see its capacity, so you can see its size.

Caused by improper operation, the original file system is corrupted, manifested as unable to open (a few can be opened, can see the files inside, but will show write protection, unable to operate on it), unable to format, as far as I know, can only be re-produced through mass production tools

It is recommended that you first use the chipgenius software to test what type of chip your USB flash drive is, and then go to the Internet** a corresponding mass production tool to reshape it for mass production or low level, in order to achieve the factory settings, this will be more troublesome, but no way, if it is a 1G, 2G disk, I usually recommend throwing it away, I hope you can succeed!

Well, mass production tools recommend that you go to Digital Home** their mass production tool image package, which integrates almost all the mass production tools, you just try them one by one, remember, there will be many different versions of mass production tools for the same model of chip.

By the way, if you want to save the data inside, it is recommended that you **easyrecovery this software to recover the data in your USB flash drive first, and then mass production, easyrecovery This software has a good reputation.

Of course, the best way is to go to a dealer and ask him to repair or replace it for you.

If you remember it correctly.

With 360, there's a system fix there.

Viruses can also cause this problem, by the way with 360 antivirus, physical examination.

No matter how it is formatted, the U disk must have at least a few kib of used space, which is the normal file of the U disk itself, and it cannot be found!

Some files are hidden and cannot be seen, even if you turn on Show Hidden, I don't know what file you have? It doesn't matter if you look at it once.

Kill it with Kaspersky, or try it on a different computer.
