Ways to distinguish the authenticity of Hitachi mobile hard disk on the market
Package
The box of genuine Hitachi mobile hard disk has a better texture and looks firm and thick. And the blue part is more pure, and the printing on the box is more exquisite and clear. The fake box has a thinner texture, looks softer, the text color on the surface has traces of like discoloration, and the blue color is either too dark or too light, not as pure as the genuine one.
Logo
The logo on the surface of the genuine mobile hard drive is silver-gray in color and looks very three-dimensional. The logo of the fake product looks gray, but the sense of light is not as strong as that of the genuine product, and lacks the penetration of the silver color. And the logo's writing surface is very smooth, lack of three-dimensional sense. In addition, the casing of the genuine hard disk is made of matte material, which does not leave any fingerprint traces after touching, and is not only beautiful but also durable. The shell of the fake is just a normal material, smooth to the touch, and will leave traces of fingerprints.
Back
The S/N number is on the back of a genuine portable hard disk and is the same as the number on the outer packaging. When comparing the S/N number of fake products with the number on the packaging, some of them are different, and some of them are printed in a blurred manner, which I think may be a loophole for counterfeiters to cover up the inconsistency of the numbering. In addition, the genuine label of the letters and numbers printed on the label are clearer, and more slender. The printing on the fake is worse, the font is thicker than the genuine one, and the color is grey.
USB interface
The genuine USB interface is selected from the best material, looks bright and clean texture, and the latest models are 3.0 interface Oh, can reduce the time of data transmission. Fake USB interface on the selection of materials is not as good as the genuine, looks very poor sense of brightness, some of the black, and a closer look at the top of the dust, indentation and other impurities, and the installation of the general are more common 2.0 interface.
Shockproof
After we open the outer packaging, the genuine product has a layer of shockproof plastic shell, the plastic shell material is relatively hard, and pressed three-dimensional feeling is very strong, and the contact with the mobile hard disk is relatively close, so as to better protect the hard disk. Fake shockproof shell touch is not as hard as the genuine, soft, with a hand pinch can become a very small ball. And we will also find that the shockproof case is a circle larger than the mobile hard disk, which will grind the mobile hard disk in transportation, not to mention the protection of shockproof.
Precautions
On the outer packaging of the genuine product will be affixed with a scratch coating that can be checked for anti-counterfeiting, and the scratch coating is intact. When buying, you can see if there is this scratch coating, if not or damaged, you should carefully consider whether to buy.
