What s going on with my USB flash drive What s wrong with my USB stick??

The system can't be formatted, or it prompts "Please insert the disk", and when you open the USB flash drive, the inside is garbled, and the capacity does not match itself.

Maintenance idea: For this phenomenon, it can be judged that there is no big problem with the hardware of the USB flash drive itself, but it is just a software problem.

USB flash drive failure is probably the main problem. For the phenomenon of not being able to write files and not storing, it is generally caused by poor flash performance or bad blocks. Do you have a clear idea after reading it?

Casually explain,U disk is different from ***,He doesn't have firmware,But some manufacturers put their own software in it,There will be no low grid。

Tell you a very simple way, that is, when the main control is damaged or the corresponding repair tool cannot be found, you can use the USB flash drive kit to make a new USB flash drive, the method is to remove the flash of the faulty machine, and put it on the new PCB board. The USB flash drive kit includes a set of PCB with main control (divide and divide) and shell), which is very simple to repair and more convenient to do data recovery.

Talk about the correct setup and use of flash memory.

Many users complain about the poor quality of their flash drives due to incorrect settings after buying flash drives, and there are many problems, but the same flash drives are used on other people's computers, and everything is normal. In fact, many users' complaints are caused by their incorrect computer settings, and the author will introduce the optimization process of flash memory to you here.

The slow read and write speed of flash memory is mainly due to the fact that the system does not have the option to "open and write to cache", and the main way to turn this on is to:

1. Under window 98 and me, you can right-click "My Computer", select "Properties Performance File System Removable Disk", check the box before enabling the "Write Cache Later" dialog box, press "OK" and restart the computer.

2. Under Windows XP, you can open "My Computer", right-click the removable disk, select "Properties Hardware", then select the drive where the flash disk is located, click "Properties Policy", and select "Optimize for Optimization......Click OK to restart.

When the write-after-cache is turned on, the read/write speed of the flash memory can be increased by at least a quarter, for example, for a 100MB file, it only takes 10 seconds to turn on the write-after-cache function, and at least 40 seconds without turning on this function.

The virus will create a "Your Folder Name" based on the name of your folderexe file, and there will be multiple and files.

This is the nature of the virus. You probably should know that this is the file, which is run automatically by the virus.

My Computer - Tools - Folder Tab - View - Show all files and folders, hide the extension of known file types, remove the item with " ", and then click OK. At this point, the disguise of the virus will be discovered, and the prototype will appear. Just delete them all.

Show all the documents according to the above method and then put it. Delete all exe files, and delete as well.

Then remove the hidden attributes of all folders on it Method: the folder with the exe suffix, right-click - Properties - Hide Remove it.

second: Displays the hidden folder.

Start button – run the command, type cmd, press enter, and enter the following statement:

x: [Enter] X is the drive letter displayed by the USB flash drive in the computer.

attrib -a -r -h -s s d [enter].

Or create a new notepad with the statement "attrib -a -r -h -s s d", save it as a file, put it in the root directory of the USB flash drive (you can put it in the directory that needs to be processed), and double-click to run.

Right-click the disk where the USB flash drive is located to check its properties and see if it occupies space. If it's occupied, it's a virus, the folder is hidden, just tick the graphics card to hide the file in the folder option. If it doesn't take up space, it's a USB flash drive problem.

A computer infected with a USB flash drive virus may have the following symptoms:

1. The computer runs slowly, there will be fake death, stuck phenomenon, and the installed anti-virus software can not be opened (only by using special system first-aid tools such as Kingsoft system first-aid kit to carry out emergency anti-virus on the system can the normal operation of the system be guaranteed).
