A few years ago. Once I went to beiyou to play and saw a booth Selling u disks on campus. I asked about the price. 8 GB Kingston U disk was 99 RMB. Just the first day, a colleague told me that the USB flash drive has been reduced recently, and 8 GB is only 99, so I bought one with an itch. When I came back to use it, I felt that something was wrong. The reading and writing speed was too slow. When I put more things, I could not read much. I quickly found the software to detect it. It was a fake, and it was modified with a 4 GB counterfeit movement. Today I will share with you the software and methods used for testing.

First, let's explain how to determine whether a Kingston USB flash disk is true when no software is available. Intuitively, You can carefully observe the labels, anti-counterfeit marks, and anti-counterfeit phones on the USB flash drive. The rough ones are generally fake. Note the following two points:

  • After a Kingston USB flash drive is connected to a computer, the computer displays the "Kingston" tape ), the Counterfeits are generally "removable disks;
  • When the Kingston U disk is reading and writing, the light on the back will flash, but the counterfeit will not be bright.

Next we will introduce the first small software: chipgenius. It can identify the type, manufacturer, brand, and other information of the USB flash drive (or other USB devices. This software is green and small, easy to carry. It is one of the essential tools for purchasing a USB flash drive. The following two figures show the comparison between the true and false Kingston USB flash drives identified by this software. The true USB flash drives are issued by the company, and the false ones are bought by beiyou.

It can be seen that the key difference lies in the product vendor and product model, which should be the Kingston datatraveler 2.0, the counterfeit is usually something like USB 2.0 flash disk.

It is strange that I run the software on Vista in English. The version is 2.64, and the version is 2.70 on XP in Chinese.

If the chip is fake, I can bear it. the most annoying thing is that the actual capacity of the chip is only 4 GB. The software introduced next can be detected, called mydisktest. This software is very functional and my favorite isExpansion DetectionAndBad Block ScanThe scanning speed is faster than that of my own program. In addition, it can perform speed testing and block shielding. If you don't talk nonsense, simply compare the figure, or I have a fake one or two USB flash drives.

It can be seen that I modified this fake USB flash drive with a four-Card 4G movement. Because I bought it on the roadside on campus, even though I needed a receipt (called Hailong's event here), the booth on the receipt was also fake. At present, I have to temporarily use mydisktest to block the bad block (otherwise, the content written to the file exceeds 4 GB will not be written, but no error will be reported, it is not found until the data is read. All content is 0 × 00 ).

Fortunately, the two software versions are very small. Here we will download them directly (the detailed instructions are provided in the compressed package, so I will not say much ):

  • Chipgenius v2.64 (113 K) MD5: 2628f1748e558bd71ab661ae1ab27aa5
  • Mydisktest v2.50 (610 K) MD5: 7d4bfeb1e01f748fe3bd2b6a590bd83b

I really want to buy a USB flash drive from the street one day with my own copy, perform on-site detection, and expose the tricks of these profiteers.
