The DIY industry is gradually recovering, and another wave of installations is coming. Businesses in the industry are doing their best to "collect blood" after suffering losses from the "mine disaster". The black industry chain of hard drives, don't think that this matter is far away from you.
01 How did the fake hard drive come about?
First, there are no fake hard drives. The "fake hard disks" we are talking about today are some refurbished disks or mining disks. At present, there are only three companies in the world that can manufacture mechanical hard drives: Seagate, Western Digital and Toshiba. There was Hitachi before, which was acquired by Western Digital in 2011.
How did the "fake hard drive" come about?Relevant statistics show that in 2022, the shipment of desktop mechanical hard drives will be 40 million, while the OEM refurbished machine will be 10 million, and the number of refurbished hard drives will almost reach 30%.
The merchant will block the original bad sectors of the mechanical hard disk. For example, the original 3T mechanical hard disk has 800G bad sectors, so simply block the 1T capacity and bad sectors together.Then print the hard disk OEM, replace the socket accessories, and paste the new 2T OEM and factory date.Then clear all the data in the hard disk, crack the hard disk information and rewrite the new information, thus completing the transformation.
02 It is difficult for users to detect counterfeit hard drives after refurbishment
After purchasing a mechanical hard drive, the user will use the relevant software to check the hard drive.Factory information, serial number information, see if there is any trace of being inserted into the hard disk slotBut merchants are very mature in refurbishment technology, and people who users can think of have long wanted to appear in front of you.
Very low cost of refurbishment
Since the data information of the mechanical hard disk has been modified, and the appearance and gold fingers of the socket have been refurbished, users basically do not know whether they are buying a mining disk or a refurbished disk without removing the hard disk.
Some refurbished goods cannot be found even after on-board testing.
03 How to identify and choose a reliable hard drive?
So, how to choose a reliable disk?
Some foundry technology is very poor, it is not difficult to see carefully
First, if you can't find it on the machine, you should go to the OEM for clues. In recent years, a large number of Hitachi hard drives in the industry have been easily cracked due to modification of internal information, resulting in a large number of counterfeit hard drives put on the market with sophisticated refurbishment techniques.
How to choose a reliable mechanical hard drive?
Choose some reliable stores to close the pit. Although the price of the official self-operated store is expensive, at least it will not fly into the flames, and now the mechanical hard drives below 3T are thin and light models.If you buy a 1T or 2T hard drive, it is still a very thick old modelSo do not rule out the possibility of refurbishment. Asking the customer service will also tell you that it is "saved". If there is any, please return it!
Second, if the quality of the hard drive and after-sales service are important, then enterprise-class hard drives are recommended.The quality of these hard drives is guaranteed and supports personal delivery. This needs attention. Must buy National Bank!At present, the share of parallel imports is relatively large, and users should pay attention to distinguishing them.
