1, the U disk chip can not be detected with ChipGenius, it should be a black disk, can only be removed from the disk, see the jet code on the back of the master chip to determine.
2, what you use to detect, it is recommended that you test the next latest (ChipGenius) to try, if you can not test what chip, it may be black disk. Under normal circumstances, if the capacity of the black disk is 4G, what is the use of itQuestion, may be at a loss on the price.
3, you can not detect the chip model, it can not download the corresponding mass production tools to mass production. Which means your flash drive is a black one, a knockoff.
4, I think it should be the real thing, ChipGenius often can not detect the U disk information, there are many reasons on the Internet, not necessarily your U disk problem.
5, the steps are not complicated, first use ChipGenius chip wizard this small software to detect your U disk master. According to the test results to find the corresponding mass production software, and then pay attentionLook at the instructions for the production software before you start mass production. If you can not detect your U disk master, then the U disk is mostly black disk, not energy production.
6, the use of this type of U disk can be basically a cottage disk, can also be called black disk. Specifically you can go to the digital home to download mydisktest test. chipgenius is used to detect master control models and FLASH models, and cannot directly identify black disks.
In the open "Device properties" window, switch to the "Details" TAB, click the "Properties" drop-down list, select the "hardware ID" item, then you can view the PID and VID information of the current USB flash drive.
Use chip worry free, etc. You can check the master software to know this information. I forgot to mention that this can be modified in the production software. Generally also look at this can know whether it is really an expansion disk. The general number is 123,456 or something like that.
Detailed information display: setThe prepared VID, PID and SN code are the key identification of USB devices, chipgenius for your science, VID is the code applied by manufacturers to standards organizations, PID is the manufacturer's custom, they together constitute the unique identity of the device.
The most accurate and violent method - remove the U disk to see the chip directly 2) Judge the master according to the software vid & pid combined with the list of known USB manufacturers. But vid & pid can be changed at will, for inferior flash storage U disk may not be allowed; It can also be judged by the software VMWARE.
It can detect the chip model, manufacturer, flash memory type and other information of the U disk to help users understand the specific parameters and performance of the U disk. At the same time, it can also perform speed tests on the U disk to check whether there are problems such as bad blocks on the U disk.3, finally recommend you directly in the chip wor-free test results page, click the tool download, you can directly find the corresponding mass production tools, but we must bear in mind, because our main concern is the number of the model, because in many cases, the software and the U disk master chip digital model does not match, U disk will not be able to mass production.
4, downThe on-board chip detection software chipgenius, insert the USB flash drive and run chipgenius. The interface shown in the figure shows that the USB flash drive in this example is 8G Kingston USB flash drive, and the detection result is Group Link PS2136 chip, VID=13FE, PID=1F27. Search online and download the mass production tool software. In this example, the Phison UP13UP14UP12 mass production tool is used.
5, there are two mass production tools for detecting the U disk master model, one is the chip wizard, and one is the chip worry free. Are decompressed, run the EXE file, the program will automatically detect the main controlThe information. If one can't find the main control model, try another one.
6, MyDiskTestMyDiskTest is a U disk /SD card /CF card and other mobile storage product expansion identification tool, usually used together with ChipGenius, different from ChipGenius comprehensive, The most practical function of this software is to quickly and accurately identify and detect whether the storage device has been expanded capacity and shoddy.
U Disk speed measurement software has a variety of, among which the more commonly used include CrystalDiskMark, HD Tune and ATTO Disk Benchmark.
CrystalDiskMark: This is a widely used hard disk performance test software, it can test the U disk read and write speed, continuous read and write speed and random read and write speed.
There are many U Disk speed measurement software, the following are some common U disk speed measurement software: ATTO Disk Benchmark: This is aEasy to use disk transfer rate detection software that can be used to detect the read and write rates of hard drives, USB sticks, memory cards and other removable disks.
