Power failure of U-disk mining

1. 1. The USB flash disk of the desktop is not powered enough and cannot be used
because the working current required by the U-disk is relatively small, it can be used smoothly when it is inserted into the desktop computer. If it cannot be used, we can plug the U-disk into the USB interface at the back of the desktop computer chassis, because the power supply of the socket at the back is large. If you can't use it before and after, you can consider whether the U disk or USB interface is broken
2. The power supply of the laptop USB flash disk is insufficient and cannot be used
if your laptop is running on battery instead of power supply, it is likely to cause insufficient power supply, because the output in battery mode will be less than 500mA, sometimes higher. Due to the unstable power consumption, it will be unrecognizable. It is recommended to plug in the power supply and then use the USB flash disk. There is also a case of notebook USB circuit aging, there is no good way to solve this problem, use the data cable with additional power supply connector
3. Make sure there is no problem with the computer and USB interface, and the power supply of the USB flash disk is insufficient
in this case, your USB flash disk may need a large power supply. You can try to buy an extension cable with one interface and two USB interfaces at one end, and plug the two interfaces into the computer at the same time, which can usually solve the problem of insufficient power supply.

2. The software should be right. Maybe it's the wrong setting. You can reset it in yourself. After successful mass proction, you need to format the partition (U disk) in the system. Can be used. Same as new hard disk)

3. 12m should be unreasonable, it is estimated that you have problems in the operation process, or U disk has a bad path. But in theory, it can be expanded at will. That's just the displayed capacity, which has nothing to do with the actual capacity.

4. Find a computer, it to the computer, replace it with a memory card or U-disk, if you can it successfully, you will be saved; if you can't it successfully, you won't be saved.

remember the praise

5. The capacity expansion of USB flash disk is to expand the capacity of USB flash disk display through mass proction. In fact, there is not so much capacity. Generally, the capacity expansion of USB flash disk is not stable, and it is not recommended to buy it.
if you have any questions, please ask me, and I will reply to you at the first time. If you have any help, please help me adopt it. I wish you a happy life~

6. U-disk expansion: a method to increase the capacity of U-disk. Physical expansion is to connect several U-disks together through connectors to increase the capacity of U-disk. Usually, this kind of U-disk is displayed as multiple U-disk symbols on PC
the expansion of USB flash disk is mainly aimed at the counterfeiters in the market. Through technical means, a small capacity USB flash disk can display more than its own storage capacity on the PC and be sold at a high price. For example, a 256 m USB flash disk can be expanded to 8 g by technical means, and then sold at the price of 8 g. if things are stored in the USB flash disk, all the things over 256 m are lost. At the same time, the storage speed of the USB flash disk is very low, and the symbols of the USB flash disk are often displayed in exe format on the PC, which is similar to poisoning and can not be used. Many parallel U disk often do similar expansion, can be detected through the software u disk expansion
physical expansion is to connect several USB flash disks together through connectors to increase the capacity of USB flash disk. Usually, this kind of USB flash disk is displayed as multiple USB flash disk symbols on PC.

7. Copy all the data that need to be saved in the U disk, and use the U disk low-level format tool for low-level format. The general practice is this~~~

8. I believe many people have bought the so-called expanded USB flash drives. Most of these expanded USB flash drives are fake Kingston, Samsung and other famous brand procts. Although we know that they are expanded USB flash drives, it's not convenient to continue to use them. It's a pity to throw them away. Now that you've bought a fake, you can accept it. It's OK to put some information and songs at least. But it's more convenient to use it only after you know the actual capacity. Here's a way to restore and expand the U disk< br /> http://jingyan..com/article/95c9d20d86347aec4e7561de.html
hope to adopt

9. There's no way to measure the main control model. It's like this after it's disassembled
