The manufacturer information Generic of the USB flash drive means no trademark.

1. It means that your USB flash drive is not a brand product, and the detection tool can't detect the manufacturer information of the USB flash drive, so Generic is displayed.

2. Generic means no trademark. If your USB flash drive is nominally a brand product, at least it is not genuine, and it may be an OEM product or a non-main factory product.

The method to judge whether the USB flash drive is true or false is as follows:

1. Use software tools to detect whether the USB flash drive is an expansion disk, such as MyDiskTest, and then open the software after plugging in the USB flash drive, and you will know as soon as it is detected.

2. Use files to detect, which is the simplest and most effective method for the expansion disk. Both mobile phones and computers can be operated. The step is to directly transfer a file with a size of 1G (for example, for a disk with a capacity greater than 1G) to the disk.

Then copy and paste this file in the disk continuously, and then constantly observe whether the thumbnail of the newly pasted file is abnormal, and see if the file can be opened normally when it exceeds half of the nominal capacity or there are thumbnails with abnormalities. Repeatedly, if the file is damaged, it is an expansion disk.

3. Look at the reading and writing speed. The writing speed of 8G is more than 4MB per second, the reading speed is more than 14MB per second, and the speed of 16-32G is doubled by adding 4MB on the basis of 8 G.

4. Look at the packaging. The genuine packaging is clearly printed and has anti-counterfeiting code.
