How to authenticate a USB flash drive and how to use MyDiskTest

1. MyDiskTest It is only a detection software, it can be used to detect whether the U disk is an expansion disk, and it can also be used to shield the bad blocks of the U disk and detect the integrity of the files copied to the U disk. It cannot be mass-produced for USB flash drives.

2. The mass production method is as follows:

Chipgenius chip sprite and.

Chips worry-free. chipeasy)), the operation method of these two software is basically similar, you can choose any one as a detection tool, to detect the model of the U disk main control, if one of them can not be detected, you can change the other for detection.

3) Enter PID and VID in the mass production settings, this value is in the main control chip detection tool, when testing, pay attention to it yourself, and you can do it.

4) After entering, click the Start Mass Production button to start mass production.

5) After the mass production is over, the information of the USB flash drive will be displayed, click the all pop-up button, and then pull out the USB flash drive.

Figure 1) After inserting the USB flash drive into the computer, mydisktest will detect all the inserted removable disks by itself, select the disk you want to detect, see Figure 2:

Figure 2) Click on "Start Testing This Drive Now" and wait for a while and the result will be known immediately. That's right, it's that simple! Figure 3 shows:

Figure 3) Black Chip Detection.

If you select "Simultaneous detection with black film", you can see from the results that the actual capacity is slightly smaller than when it is not selected, and the results are more rigorous. Figure 4: Figure 4).

MyDiskTest is a tool to identify whether the capacity of a removable storage device such as a USB flash drive or SD card is expanded, and the storage space occupied by the software is only 1MB. It can also detect bad blocks in the flash memory of the storage device, whether it uses black chips, and can test the read and write speed of the storage device. Next, I will tell you how to use mydisktest these three functions.

01 First open the software, then plug in our USB flash drive, and the software will automatically detect the USB flash drive that needs to be tested. Then check the options that need to be tested, and click the "Start Test" button to start the test.

02 First of all, we test whether the USB flash drive has been expanded, and after clicking Start, the software will soon give the test results. If the test passes, it indicates that the USB flash drive is not an expanded USB flash drive.

03 You can also use the "data integrity check" function to test whether there is damage to the storage module area of the USB flash drive. Back up the data in the storage device before the test to prevent data loss.

04 Finally, we can test the reading and writing speed of the USB flash drive, and the test results will be displayed directly in the software interface.

There will be an impact, but it's basically negligible.

MyDisk Test can perform expansion detection, bad block scanning, speed back test, aging test, and bad block shielding on the USB flash drive.

However, the main function of mydisk test is to expand the detection, which is to use software to increase the system space of the USB flash drive, but the physical space remains unchanged. To put it simply, it is to change the USB flash drive of 1G or other capacities with software to a USB flash drive that displays 8G or other capacities (n>1) in the computer or mobile phone, but the actual capacity is still 1G or others. If it exceeds its actual capacity, some of the files or data will be damaged or lost.

At the same time, it can also detect whether there are bad blocks in the flash memory, whether the black chip is used, do not destroy the original data of the disk, and can test the reading and writing speed of the U disk.

The basic principle is to read and write the USB flash drive, and I can't say how specific it is.

This detection is not as good as copying a few movies into it yourself, so that it is faster, and the movies that can be put are the actual capacity.

That is to say, this USB flash drive may be a copycat version, or a repair disk.

If you want to fix it yourself, you can use the chip wizard to find the mass production software of the corresponding chip and then mass produce it yourself.

However, if it is a new disk, it is recommended to replace it.

If your USB flash drive is Kingston's, the likelihood of counterfeiting is even greater.

It is best to be able to check the code of the USB flash drive on **.

Hello landlord.

I just put mydisktest into the USB flash drive that needs to be tested, and then click "Start testing this drive now".

How can this be seen? The easiest way is to take a look at how many wires there are in your USB plug, if there are 4 large and 4 small ones, yes, only 4 large ones. Hope it helps.

Yes, of course, but I don't know if there is a quality problem.
