Case:The 320G desktop hard disk has a total of 4 partitions, one of which cannot be accessed, prompting formatting.After many years of photos, I hope that all can be restored. Solution:The engineer found that the hard disk had no physical problems through professional equipment testing.An analysis of the disk editing tools found that the system…
Case:After the customer reinstalled the system, there were 4 partitions in the original hard disk, and now it has become a partition, and the data inside is gone. Solution:Customers take the entire host to our center for data recovery.After removing the hard disk of the customer host, the hard disk was further tested to confirm…
Case:After the customer’s Samsung notebook fell, there was a “Kaka”” knock on the hard disk. Solution:This kind of problem is generally caused by the failure of the foundation plate after the magnetic head is damaged. Of course

Hard Disk Drive Crash
Take the case of computer systems. We become so used to working on the computer on a regular basis that we are rarely ready to face the consequences if things go wrong. This is truer of a computer hard disk drive crash than of anything else. Hard drive malfunction can be divided into two types: one is the so called Firmware Level malfunction that can be repaired using relating software or factory commands; the other one left is the Physical Level malfunction caused by physical hard drive components damage. As to the latter Physical Level crash, the typical case in data recovery practices is that the head crash and serious platter scratches caused by direct contact between the head and the platter surface; such drives manifest themselves as undetected, staying BUSY, besides an ominous scratching sound may start to emanate from the disk. This is a serious problem. It is indicative of nothing less than a crash of the hard disk drive.
Functioning of a Hard Disk Drive
In order to understand the problem of a hard disk drive crash, it is important to first understand the mechanism of a hard drive. Only after knowing how the disk drive functions can one understand the nature of the problem.
Components
Read-Write Head: The read-write heads of the hard disk drives are those mechanisms that, as the name suggests read or write the data from the magnetic fields of the platters.
Hard Disk Platter: A hard disk platter is a circular disk within the hard disk drive. It is circular in shape and the magnetic media of the disk drive is stored on it. Generally multiple platters are mounted on a single spindle of the hard disk drive.
Lubricant Layer: This is the topmost layer of the platters and is made of a substance similar to Teflon. Carbon: There is a layer of sputtered carbon just below the lubricant layer. Magnetic Layer: This is below the layer of carbon.
Functioning
The magnetic layer of the hard disk drive stores all the data. The two layers of carbon and the lubricant like material saves this magnetic layer from coming into accidental contact with the read-write head of the disk, we can say they exist as the protection layer of the magnetic layer (of course, another important function of them is to maintain the stability of the flying read-write head)
About DTIDATA Data Recovery When you enlist the services of DTI Data recovery, you can expect the most efficient, cost effective hard drive recovery in the business. For years DTI Data has offered a fresh approach to hard drive and data recovery. They were the first to recover hard drive settings from the partition sector…
There is a direct correlation between the technology and economic interest. An ordinary PC’s hard disk stored the important day. If the hard disk is physically damage, the charge for a single hard disk drive is from $350-$1,000. There is a company who had the damaged hard disk. Their data is not classified. They sent the HDD to their location data recovery company who can’t extract the data. Then they delivered the HDD to another small company in Florida. After 1 month, they still not got back the data. Last, they find a professional data recovery company. They got the data back after 24 days. Be Charged $570. Another company has a damaged server. They asked the data recovery company to repair it. The price was $3,000. They can’t repair it at that time. They needed to bring it to their company. The price became $12,000.
How about the tracking charge? It is from $300-$750. This price is just to recover data from a physical damaged HDD. So please think is there anyone want to teach this technology to you.
It is common they don’t want to you know this technique.
Why many people do not willing to do the HDD repair business now? Repair HDD is much cheaper than data recovery. If you just repair HDD, perhaps you can’t afford the rent. Do data recovery business, maybe you can’t get an order per year. In some small towns, you should also repair other things to make a living. In some large city, it is possible to do data recovery business professional. However, the rent is also high. In some hot spot, a 40 square meter place should cost you $60,000-70,000. Maybe it will be higher. Not everyone can afford it. Furthermore, you should earn it little by little. Can you make up your mind to do this business? Not all of you, right?
So, how can you get into this field?
First, you can do this business from small. You should ensure the successful rate. Do not receive the case which you don’t have assurance to extract the data (Only if your customer told you it didn’t matter. You can do it and get experience). When you have a little repute, your business will become better and better. Then you can develop your company as a professional company. When you are more repute, you will get more cases. This time, you should employ staff to help you. Maybe you also afraid your technique be learnt by others now.
We first look at the following two pictures. Picture 1 is the “BIOS CHIP” of the circuit board. When we replace the PCB, we need to swap the “BIOS CHIP” with your original PCB. Picture 2 shows the “Board Number” of the board, and the “Board Number” must be the same! FAQs of 2060-800041-000 PCB…
Case:The hard disk is at work, and take it by hand, because the sweater on the body is electrostatic, and the electricity is used to throw away the hard disk, but it is found that the hard disk is not transferred and cannot be recognized by the computer.There are a large number of design documents…
