Although U disks are now very popular, problems arise in endlessly, especially the problem that U disks cannot be formatted, which is particularly worrying. There are many reasons for this problem, which need to be solved according to different situations. Now we will use examples to introduce the strategies to deal with this problem!

Fault phenomenon:

1. You can see the disk symbol on the XP system, and you can also enter and open it. However, the files inside cannot be deleted or copied and pasted, and the USB disk cannot be formatted. Right-click to format, prompting that the format cannot be completed.

2. On the XP system, you can only see the disk symbol, but you cannot enter and open it. Do you want to format it? Select yes, but you cannot format it, and the disk space is zero. Right-click on Properties and see that the partition format changes to RAW format.

Cause of failure:

1. When exiting the U disk, it exits abnormally. Please pull out the U disk directly.

2. The U disk is poisoned, such as gray pigeon, auto virus, etc. The virus is not completely checked or the virus destroys the U disk system files.

3. The solder joints at the U disk interface and the circuit board inside the U disk are loose (this hardware problem is not solved in this article).

　Solution process:

　1. Before inserting the U disk, press the shift key, open my computer, do not double-click, and directly format the U disk in fat format. It has no effect and fails.

2. Enter the following command format x: fs/fat32 under DOS. It has no effect and fails.

3. Format in safe mode and format in disk management, it has no effect and fails.

4. I tried USB flash drive repair programs downloaded from the Internet, such as MFORMAT and UMSD, but the results were ineffective and failed.

5. After trying all the methods, I just need to disassemble the USB disk. I thought that since I could recognize the drive letter and was prompted to format, it might not be a hardware problem. In the end, I had to resort to a unique trick to refresh the mass production of USB flash drives and succeeded. I also focus on this method.

Preparation before mass production:

Before mass production, the data in the USB flash drive needs to be backed up. Use the Chinese version of EasyRecovery Pro v6.10 to do this work. The installation and use of EasyRecovery Pro will not be described in detail in this article.

U disk mass production:

Step one: If you want to mass produce refresh, you must know the model of the U disk chip. Different chip models require corresponding mass production software. How to find the chip model without opening the U disk? A small software is OK.

Chip Genius V2.64

How to use: Insert the U disk or MP3, MP4, flash drive, etc. into the computer, open Chip Genius and click on the drive letter you want to view, you can see the manufacturer, chip type, chip model, etc.

Step 2: Know the chip model and download the mass production software of the corresponding model

There are many mass production software for mainstream chip models here: http://bbs.mydigit.cn/read.php?tid=4345

Step 3: After the software is ready, start mass production. Insert the U disk or MP3, MP4, flash drive, etc. into the computer, open the downloaded mass production software, the software will automatically search for the U disk information, click "Flash Disk Settings" to format the U disk to be mass produced.

The U disk cannot be formatted is a problem we often encounter. Since there are many reasons for this problem, we need to investigate according to different situations in order to find a solution that suits us. If the situation you encounter is the same as the example in this article, you can safely follow our steps to solve it. I believe that through these tips, your USB flash drive will be able to come back to life.
