The secret of the black hard disk industry chain: Have you been recruited for 10 million refurbished disks every year? -PC computer, mechanical hard disk, solid-state hard disk – Fast Technology (the media of Drive Home) – Technology changes the future

The DIY industry is gradually recovering, and another wave of installations is coming. After the businessmen in the industry experienced losses from the “mining accident”, they are trying their best to “recover blood”. 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 of all, there are no fake hard disks. The “fake hard disks” we call 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 that, but it was acquired by Western Digital in 2011.

And 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 OEM refurbishment will be 10 million, and the number of refurbished hard drives will almost reach 30%.

Merchants will block the original bad sectors of the mechanical hard disk. For example, the original 3T mechanical hard disk has 800G of bad sectors, then simply block the 1T capacity together with the bad sectors.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, and rewrite the new information after cracking the hard disk information, thus completing the renovation.

02 It is difficult for users to detect fake hard drives after refurbishment

After purchasing a mechanical hard drive, users will use related software to check the hard drive.Factory information, serial number information, and see if there is any trace of being inserted in the hard disk socketbut merchants are very mature in refurbishment technology, and the people that users can think of have long wanted to be in front of you.

The cost of refurbishment is very low

Since the data information of the mechanical hard disk has been modified, and the appearance and the 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 disassembling the hard disk.

Some refurbished goods can’t 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 OEM technology is very poor, it is not difficult to see if you look carefully

First of all, if you can’t find it out on the machine, you should look at the OEM for clues. In recent years, a large number of Hitachi hard drives in the industry have been easily cracked due to the modification of internal information, resulting in a large number of fake hard drives being put into the market, and the refurbishment process is excellent.

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 there will be no moths, and now the mechanical hard drives below 3T are thin models.If you bought a 1T, 2T hard drive, it is still a very thick old modelthen the possibility of refurbishment is not ruled out. Asking the customer service will also tell you that it is a “stock disk”. If there is, then return it decisively!

Secondly, if the quality and after-sales service of the hard disk are very important, then enterprise-class hard disks are recommended.The quality of these hard drives is guaranteed and they support personal delivery. This point needs to be paid attention to. Be sure to buy the national bank!At present, the share of parallel imports is relatively large, and users should pay attention to distinguishing them.
