Recently some time, some of the repair of unknown sources of hard disk into the market, a lot of friends have eaten the loss, in order to let everyone know how to identify rework hard drive, I will understand the difference between the way I tell you.
Because of the high technical content of the hard disk, there are so many places in the world to produce, so in the warranty period of the hard drive, are back to the original manufacturers to repair, and the manufacturers in the maintenance of hard disk, will be on the plate to make the corresponding logo, which has become an important symbol of our differences, but because it is written in English, Ignoring the past may be overlooked if you are not careful. As shown in the WD hard drive, in the circle shown in the figure, the date is followed by a "R" letter, which proves that the circle marks the date of the repair, not the production date, and that the light blue "refurbished" (meaning of the English renovation) can be seen in the callout box. In the upper right corner there is a more prominent "refurbished", we see on the hard disk such a mark, we must not buy. In addition, if the price of the hard drive is much cheaper than elsewhere, it is possible to rework the hard drive, or "cheap not greedy."
Finally, when you buy a hard drive, it is best to go to the regular agents to buy, but also to buy a rest assured.
