Can a shrunken USB flash drive be repaired? Can you use a shrinking USB flash drive

It can be repaired, but you need your USB flash drive model, and the corresponding mass production tool can be restored to its original capacity by flashing its own firmware. It is also possible to use other software, such as mydisktest

You can search on the Internet and use this detection and shielding to expand the capacity. It is easy to have garbled and destroyed data when expanding the U disk, and it must not exceed the real capacity when it is used.

In fact, some U disk itself is not shrinking U disk,But formatting changed the system type,U disk larger than 4G is recommended to use EXFAT format,You can try the following operations,Click to start running and enter "cmd" Enter "chkdsk

f (f is the U drive letter): f (f is the repair command) "After the repair check, enter "format".

f: fs:exfat" to change the system, and then take a look, if you can, if you can, if not, it means that the USB flash drive is a copycat.

If it's a shrinking USB flash drive, even if it's reformatted, it's 4G, because it's been modified. The easiest way is to copy in 2G files (larger than 500M anyway), check it out, some files only have a directory without content, empty. Then there is the "chipeasy chip worry-free" to detect it clearly.

Can a 400M U be repaired into a 4G U?

You buy five catties of apples, JS only gives you 4 catties, can you make 5 catties?

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 drives, also known as "expansion disks" and "upgrade disks". There are two main ways to falsify. The first trick is to assemble a large-capacity USB flash drive by using discarded or defective flash memory particles, and the second is to use 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 make huge profits by defrauding consumers.

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 of the USB flash drive with quality problems.

"USB flash drive shrinkage" means that the actual capacity of the USB flash drive is much smaller than the marked capacity. For example, a 2GB USB flash drive may be 512MB, but it cannot be seen in the USB flash drive attributes.

If it's an expansion disk (according to what you said, it seems to be 512's expansion to4G),Even if you go back to mass production, it's useless.,The things stored in it will also go wrong.,The mass production tool of the U disk may not be the same as the U disk main control.,Then the mass production tool is not the same.。

It means that if you buy a 1GB USB flash drive, and when you use it, you find that its storage space is not 1GB, which is much worse, or the more you use it, the smaller it gets, that is, the shrinking USB flash drive is tampered with by a small-capacity USB flash drive. Identify whether it is a "shrinking" USB flash drive, for example, you can use the USB flash drive authenticator in 360 to identify whether it is shrinking.

The actual reserves do not reach the standard reserves.

Generally speaking, it is an error in the computer reading the USB flash drive, originally a 1G USB flash drive, after the computer reads it, there are only hundreds of megabytes or tens of megabytes!

And these tens of trillions and hundreds of megabytes after the computer reads the error, your USB flash drive is really only tens of megabytes and hundreds of megabytes, because he can't fit bigger things, and the computer will think that he can only install so much!

You can check out the explanation here!

It should be that the capacity is not as large as it actually says.

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.
