foreword
The central control CD player of my dad's car broke down two days ago. I thought the repair shop was too expensive, and I didn't need to upgrade it to a touch-sensitive navigation center control. , When it arrived, I felt that the repair shop would cost hundreds of dollars to install it, so I asked me to help him put it back together. That thing was actually produced in 2011. It has been 11 years now, but the appearance is still well preserved. In the end, it was successfully removed and put back together.
question
My dad also said that he wanted to download some songs to his old USB flash drive for listening in his car. I suddenly got stuck in the process of downloading songs, and then pulled out the USB flash drive directly, which caused the USB flash drive to enter the write-protected mode and delete it. I can't delete it, and it has become garbled. Anyway, there is nothing important, so I decided to format it.
solution process
At first, I used the disk management tool, but I couldn't format it, and then I modified the registry by referring to the online solution, but the corresponding directory could not be found in the registry. So I decided to use the U disk mass production tool to format it.
First, you need to check the hardware information of the U disk and check the specific model.
Recommended herechipgenius chip wizard, you can find it directly on Baidu.
Plug in the U disk will automatically identify the hardware information.
I am thisAnguo dominatesthe U disk.
Then go to upantool.com to search, find the corresponding master control type under the mass production toolbar, and finally find the mass production tool that matches the model below to download.
There should generally be supported flash memory models and operating instructions in the compressed package.
After downloading, unzip and open the exe executable file, and the U disk can be recognized.
He himself has a flash memory ID scanned by default at the beginning, but it is different from the Hynix H27QDG8T2E found by my chip wizard
Since I didn't find my model in the list, I just reset it by default (just click to start), about 40 minutes.
After mass production, it could not be recognized, so I changed other models to try, each time it took half an hour, and finally it couldn't be used. It cannot be recognized as a USB stick, only as a plugged-in device. The G disk is opened 请插入可移动磁盘, indicating that the mass production has failed...
Finally tried using the default settings (flash ID default), butModify the scan level to clear + new, Advanced Formatting.
This time it was successful.
And the mass production is over after the window is cut, the speed is very fast, and it can be recognized after re-plugging and unplugging!
Summarize
After 3 or 4 hours of fiddling around, I finally got it done, which is quite rewarding.
In fact, I have been doing it for a while yesterday, but I have been plugging and unplugging, uninstalling the device, etc., but the U disk has been write-protected, and there is no way to do it. I said to my dad, "It may be broken and can't be repaired." Then he said a sentence that gave me the motivation to continue repairing, "How could it not be repaired? It must be that your technology is not in place." So today Just got this article haha. I tried the mass production tool today, and I thought I couldn't get it out at first (because the flash memory identification code didn't find the same one), but it worked in the end.
The purpose of learning something is ultimately to serve life, and learning with a purpose in life is quite meaningful.
