Hard disk repair regulations, hard disk maintenance ideas Methods and principles?

Theoretically, the product of the same level should be replaced (at least it should be the YS series), but, having said that, hard drives generally do not provide replacement services, and the maintenance often refers to returning to the manufacturer of the hard disk to repair (that is, Western Digital's Malaysian production factory, it seems to be somewhere). The usual practice in China is to replace the good product (you can change it to a new one, but the performance is slightly inferior) However, the warranty must be recalculated by the merchant!

The first thing to correct 16MB is the accuracy with which the data is read. And not that the bigger it is, the faster it is, a lot of people are misled, and there is the kind of new and very cheap computer hardware that is said on the Internet, which is second-hand, and I tell you, there is no parallel import of computer hardware, and the patents of so many cutting-edge technologies in the world are strictly controlled in their hands. And to produce hard drives, do you know how high the manufacturing process is?

It's not like you can just throw in a few million dollars and you can do it. You don't have a technician. How to fake?

If you have a chance, you can open the discarded hard drive and look at it yourself.

Now it's either new or second-hand refurbished.

The most exposed is the so-called new ** cheap hardware. How come there isn't the latest?

For example, if I want to buy a 4870 now, can I sell it for 500? If you want to buy a GTX280, why isn't it a few hundred cheaper than the market price?

I've swapped hard drives with someone else. 80g Seagate changed to a 160g miscellaneous brand I didn't see what brand it was. My friend said that my hard drive was full of physical bad sectors, and I went to the installation shop there and replaced it with a new one.

In the future, when I buy a computer, I still have to go to the first-year point installation store to buy it. Minimum quality***. In addition, it is possible to sign a purchase contract after purchase.

Even the usual system is free.

The repair regulation is that no identical goods should be compensated close to the physical parameters.

If it's too bad, don't do it, call customer service.

Complain until you are satisfied.

That's what I want to do, and it doesn't cost anything for customer service to use a landline.

Look at whoever is the best. Ha ha.

Your previous hard disk has a single capacity of 80G, and if he replaces you with a single disk with a capacity of 160G and 8M, the cache is brand new, and the hard disk can also be! But if it is repaired, you can't ask for it, so theoretically it is too much of a loss, which is evading responsibility! Don't let him fix your original piece.,Just hit ** and let them change it to a new 160g for you.,Cache 8m is also particular!

But this after-sales service is also a little poor, do you really buy parallel goods for hard drives, we don't know this, you can talk to them specifically!

First of all, it is necessary to clarify a concept, that is, hard drive repair is not something that ordinary users can do.

Maintenance in the narrow sense refers to extracting the required data through some means, and the hard disk has no way to continue to use.

The most direct way to extract data is to use software to extract data, such as badcopy, on the premise of determining that the hard disk has logic (data input and output errors caused by circuit problems).

But most of the time, it is a case of hardware damage, such as damage to the control circuit, or damage to the inside of the disk.

In this way, the following ideas should be followed, 1) Try to find the same batch of hard disks, must have the same DMS number, so that the storage structure of the hard disk is the same, so you can directly achieve data restoration through simple replacement.

2) Rely on the residual data processing capacity of the hard disk itself to use software for recovery, such as PC3000, etc.

3) In the event that the above efforts are unsuccessful, the factory environment shall be used for "opening" operations. Scanning the disk directly will result in the loss of warranty on the drive.

All of the above principles give the maximum protection to the disk, because the data is stored on the disk.

Go),I've seen 3 hard disks that are broken like this.,Find a merchant to replace it.,During the warranty period, the merchant will definitely replace it.,The hard disk is broken inside and can't be repaired.。 If the data in it is valuable, you can ask the merchant to help you copy it out with your device, but it may not be free.

And don't disassemble it yourself during the expiration date, unless you have a clean room at home and you really don't care about the hard drive.
