What to pay attention to about the disadvantages of shrinking USB flash drives

Hello. The shrunken USB flash drive cannot be used, and the files copied in it will lose data due to the shrinkage of the USB flash drive and cannot be opened normally.

It should be good to find a mass production tool and mass produce it. 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.

The following is a tutorial on mass production that you can refer to.

For example, if you buy a 16G USB flash drive, the actual capacity is 200MB, if you send a 1G movie into it, you can only watch the first 200MB of the movie, and the back part will be damaged, which will damage the data. It is recommended to go to the big ** that is assured, or buy mainstream brands in big shopping malls, such as ADATA, SanDisk, Taidian Knight, Biaowang, Langke, etc.

Greetings.

A shrunken USB flash drive is not usable. The hundreds of documents copied into it will lose data due to the shrinkage of the USB flash drive and cannot be opened normally.

The shrinking USB flash drive exceeds its true capacity, and the files behind it are easy to lose. Copy the file to the USB flash drive, fill in it, and then select all the files in the USB flash drive, check the properties, if there is a capacity marked by the degree of it, it means that it is not an expansion disk, it may be true. If there is no capacity marked on it, it must be an expansion disk.

Situation:

First, the quality of the U disk itself, using DiskGenius to detect too many bad sectors, using the 360U disk authenticator to identify the actual size is particularly small, generally speaking, these two situations can not be used.

Second, the quality of the U disk itself is not a big problem, and there is no bad sector in the detection, and the shrinkage is not serious, so the re-mass production of the U disk, and the nominal change to the actual capacity size can also be used (will not be mass-produced, then ensure that the stored data does not exceed 80% of the actual size of the identification, (for example: nominal 120g, identification size 32g, then you store data up to 32g, preferably not more than 25g)).

It must not work.,Last time I stored the file in the shrinking USB disk,Suddenly the phone is out of power and shuts down and restarts.,After booting, the USB disk is damaged.,Caused all my files to be lost.。

Restore normal memory and you'll be fine.

Shrinking USB flash drive, also known as "expansion disk"., Upgrade Disk. It refers to the unscrupulous manufacturer using a mass production tool software to change the main control information on the USB flash drive, and mark the capacity of the USB flash drive to be much larger than its actual capacity, so as to defraud consumers and make huge profits. When the actual capacity of the USB flash drive is less than or equal to 90% of its nominal capacity, it is considered to have a shrinkage USB flash drive with hail quality problems.

The meaning of expansion is as follows:

1. Explanation of the expansion:In the time of communication, the signal is often affected in the transmission process so that the final signal becomes weak, at this time, it is necessary to install equipment such as trunk amplifier and repeater in a specific place to amplify the signal, and on the basis of the original equipment, the process of adding related equipment is called expansion.

2. Expand the disk card: It refers to the use of relevant software to make the small capacity of the USB flash drive displayed on the computer with a large capacity (such as 512M display into 2G).However, the extra memory is not used normally, and the files stored in this USB flash drive will be corrupted as long as the actual capacity is exceeded and then copied out (the available installation files become unavailable).

The so-called expansion card is an extended storage medium that expands the storage capacity of electronic devices.

U disk expansion disk refers to the use of relevant software to make the small capacity of the U disk on the computer display a large capacity (such as 512M display 2G).Not too much memory is not normal use,As long as the files stored in this U disk exceed the actual capacity,The extra capacity of the file is not available (such as songs can not be listened to,** can not be seen),Or it will be damaged if you copy it out again。

Although the actual capacity of the U disk expansion is very small, it has a lot of space outside the actual capacity, although there is no storage space, but it still makes people feel that there is space, so they are still storing files in the U disk, and it feels like it can be installed and installed. However, because its actual capacity is limited, the loaded data can be kept intact except for the effective capacity space, and the other files do not actually exist, so the data outside the actual capacity will be damaged.

In the case of an expanded disk, there is no way to restore the actual capacity of the USB flash drive by mass production to prevent data loss by not paying attention to exceeding the actual capacity of the USB flash drive.

Introduction:In real life,The U disk you use is likely to be a shrinking U disk,It's just that the degree of shrinkage is different,The following is the shrinking U disk that I carefully sorted out for you'Four features, welcome to refer to!

Shrinking USB flash drives, also known as "expansion disks" and "upgrade disks". It refers to the unscrupulous manufacturer using a mass production tool software to change the main control information on the U disk and inject the U disk capacity standard stool cavity to much greater than its actual capacity, so as to defraud consumers for huge profits.

What are the characteristics of the jujube shirt and the shrinking U disk?

1.The actual capacity is much smaller than the marked capacity, such as a 2GB USB flash drive may be 512MB, 256MB and other counterfeit! But you can't see it in the attributes of the USB flash drive.

2.During use, not only is the copy speed super slow, but also the prompt "not enough memory" will appear quickly.

3.The part of the file copied to the shrinkage tray that exceeds the actual permeability per mu cannot be read and used normally.

4.It will bring a series of troubles to consumers, such as data loss, data corruption and unreadable unreadability, resulting in work delays.
