The U disk reads and writes the USB flash drive, and the USB flash drive reads incorrectly

Change the file system of the USB flash drive, and replace the FAT with NTFS, but the sacrifice you have to make is to convert the USB flash drive before you can convert it.

Conversion Method: Windows 2000 XP provides a partition format conversion tool".

It is a DOS command line program that comes with Windows 2000, through which you can convert FAT to NTFS without destroying the FAT file system. It should be noted that you must turn off before the conversion starts.

Close all applications, otherwise the system will send an error message. Now let's get started, let's say the disk we want to convert is drive D:

1. Click the "Run" command in the Start menu.

2. Enter "Convert D: fs:ntfs" in the "Run" command window and click "OK".

3. The application will give the total amount of disk space, the amount of free space and the amount of space required for conversion, and other parameters, and then the conversion will begin. Depending on the amount of content converted, the time required varies.

4. After the conversion is completed, the application prompts "File system conversion completed".

5. Confirm and exit.

What's the difference between FAT and NTFS, check it yourself, it's hard. Hehe.

There is a bad track in the USB flash drive. It is recommended that you take it to repair, if you don't want to go, you can go to the next USB flash drive chip detection tool, find out the model of your USB flash drive chip, and then according to the model of your USB flash drive, find the corresponding mass production tool, and the USB flash drive can be used in mass production.

There is a problem with the quality of the USB flash drive. If it is less than 100 yuan, it is more likely to be bought.

Use the check USB flash drive to read and write the whole disk once.

If there is a problem, go for it.

This is caused by improper operation of the USB flash drive, 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, can not be operated), can not be formatted, as far as I know, can only be re-produced through mass production tools.

It is recommended that you first use the software chipgenius to test what type of chip your USB flash drive is, and then go to the Internet** a corresponding mass production tool to reshape or low the level of mass production to achieve the factory setting, this will be more troublesome, but no way, I hope you can succeed!

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 can try them one by one, remember, there will be many different versions of mass production tools for the same model of chip.

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.

If the USB flash drive is still under warranty, the best way is to go to a dealer and ask him to repair or replace it for you.

You plug the USB flash drive into the computer and you look at the small icon of the external hardware device in the lower right corner of your computer desktop, if there is, you can move the mouse pointer to the icon and click the right mouse button, enter management, uninstall the wildcard of the corresponding device, reinstall the driver of the device, then the computer will ask you whether to restart the computer, select Yes and it should be. My USB flash drive is also Lenovo's, with 4GB of memory, hehe.

Is your USB flash drive broken, you should try it on another computer, if it doesn't work, then you can only contact the after-sales service, repair, alas。。。 In fact, when you buy it at the beginning, you should consider that you can't just be cheap, but look at the cost performance.

Oh, what I use now is Sandisk, SanDisk's performance effect is not bad, the most important thing is the national warranty, I personally think that the cost performance is very high, so I like it I heard that I have recently opened a home***** Hehe, if you are interested, you can take a look.

For specific situations, you can try to ask their customer service, if they know, they will help you solve the problem, because their customer service attitude is super good, if you have any problems, of course, it must be relevant, and they will take the trouble to help you solve it.
