Platter Scratch Repairing - The valuable Step Into Data rescue From Crashed Drives

Hard Disk Drive Crash

Take the case of computer systems. We come to be so used to working on the computer on a quarterly 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 whatever 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 premise 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 perceive 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.

Harddisk Data Recovery

Functioning of a Hard Disk Drive

In order to understand the qoute of a hard disk drive crash, it is prominent 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. Ordinarily manifold platters are mounted on a singular 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 market all the data. The two layers of carbon and the lubricant like material saves this magnetic layer from arrival into accidental perceive with the read-write head of the disk, we can say they exist as the safety layer of the magnetic layer (of course, another prominent function of them is to utter the stability of the flying read-write head)

The platters move at an exceptional speed and the data is read from, or written on to, the magnetic layer by the read-write head which flies above the face of the platter. As the read-write head flies over the platter face its height is controlled by a thin film or layer of air entrapped between the platters and the slider face of the read-write head. That's why we mentioned that one of the functions of the safety layer is to utter the stability of the flying read-write head: the film of air floats the head over the face will be generated only when the face of the platter maintains flat and smooth.

If the read-write head comes into direct perceive with the face of the disk platters then the head can scratch through the protective layers of sputtered carbon and the lubricant material, leaving a circle scratch area to the platter. This is called a head crash or a hard disk drive platter crash.

Cause of a Hard Disk Drive Crash

The cause of a head crash can be a minute particle causing the read-write head to bounce against the platter disk. The head is made of hard materials that can scratch through all the protective layers. If the head bounces against the platter while the latter is rotating at a speed equivalent to thousands of revolutions per minute then the head is bound to scratch the platter surface. This destroys the magnetic layer of the platters. If the head begins to drag over the platter then the data loss can be tremendous. besides this the head will end up overheating or physical damage manufacture the hard disk drive stop functioning properly. Even the possibility of further head crashes increases as particulate freed on account of one head crash are scraped on to the platter surface, leaving more scratches to the platter each time you power up the drive.

Data recovery from drives with physical scratches

For data recovery from physically damaged (head crash/platter scratch) hard drive, currently the best and the only explication is to open the Had in a proper environment (such as a clean room) to replace the damaged physical head stack, meanwhile to clean up the particles on the platter, then working for data recovery from the postoperative drive. However this technique will not work for all the cases, especially when there are severe scratch area on the platter which is caused by the head crash - besides a failed head swap, the scratch area will also be an obstacle for your victorious data recovery: even after you swap the crashed head stack faultlessly, it will crash immediately on power up, manufacture the scratch issue worse and there is no way for users to read any data (even the data locate on good area of the platter) out of the drive. The presume for this situation is that when the head flies over the scratch area (it does not matter if it is trying to read from that area or not), due to the breakage of the protective layers, the head can no longer utter its floating status when it comes to the scratch area, but makes directly perceive with the platter again, the head will end up overheating or physical damage (crash or short circuit). The point of how to recover data from the outpatient drive becomes the point of how to make sure the head passes the scratch area smoothly.

Platter Scratch recovery Solution

What is Platter Scratch recovery Solution?
The Platter Scratch recovery explication is the unique technology industrialized under joint effort of SalvationData, Computer institution of Cas, Chemistry institution of Cas and Physics institution of Cas, which takes over two years of time and hundreds of thousands of dollars for R&D, integrating interdisciplinary achievements of manifold fields like chemistry, computer application and physics. It is the perfect explication for the current angle of data recovery from drives with severe platter scratch; empowering data recovery professionals who have been working on physical data recovery a deeper and more extensive capability.

Basic law of operation:
SalvationData Platter Scratch recovery law includes the following major parts:

1. High precision scratch positioner
2. High pressure cleaner
3. Nanometer filling materials spray arm
4. Devotee schedule controller

The law will first clean up the target platter using the high pressure air cleaner; then scan the platter with the optic scratch positioner to locate scratch area and label its size and depth; ultimately the spray arm contains the nanometer filling materials will fill the scratch area with the donor materials under the management of the Devotee schedule controller, so as to restore the scratches and make the scratch area revert to flat and smooth, thereby allows the head to pass the scratch area in a carport floating status so that data recovery from the good area can be achieved. The scratch positioner carries out determination and positioning towards the tiny scratches using optic imageology technology; by sending the scan description back to the Devotee schedule controller, a repairing education flow will be generated and sent to the spray arm controller for implementation. The nanometer filling materials and the high precision nozzle controlled by the Devotee schedule controller ensures 100% accuracy of the restoration; meanwhile the filling materials have been improved by trial and error, it won't cause any chemical reaction with the materials of the dissimilar layers.

As for drives of manifold platters, the law will description the platter alignment by using optic image before separating the target platter from the platter assembly; so that the platter alignment can be actually restored after the scratch restoration. The whole recovery process will be carried out by the Devotee schedule controller and the full angle robot arms under its control without user's intervention, ought to be the fastest and safest explication for platter scratch recovery available; what's more, the estimated price of the law would be colse to ,000 only, manufacture it the most adoptable and beloved equipment.

Support List

The law includes robot arms and workstations designed for thorough platters of 3.5-inch, 2.5-inch and 1.8-inch hard drives of dissimilar manufacturers; fully satisfies the platter recovery needs towards the hard drive types mentioned above. (As to those platters contains special manufacturing process and technology, such as the glass platter technology is being worked on, and hopefully it will be announced on preliminary initiate day plus 6 months).

A Final Note

What we do using this law is to carry out a padding recovery to the platter scratch using alternative materials; therefore data locate on the scratch area will be lost beyond recovery even after the platter restoration. The point of this explication is that to ensure the read-write head pass the scratch area smoothly, so that the head continues to work for reading data from the subsequent good area.

Data rescue Myths - Logic Board and Platter transfer

While many parts of your computer can be supplanted to bring it back to normal, the myth that your hard drive recovery can be as straightforward as replacing obvious components is only partially true. If you've experienced a crash, then you can understand the desperation many people go straight through when trying to find a cheap explication to recover the data. Even though the logic board exchange and platter fix explication is not free, some people endeavor to have this assistance done to save lost data and recover foremost files on their hard disk.

First, it's been reported that effective clean rooms cost associates hundreds of thousands of dollars. It's safe to say that your local hardware component technician does not have the available funds to contribute a clean room for their customers. The first error in this myth is that whoever claims to be able to fix hard drives likely does not open them in a safe, uncontaminated room like they should do. While you may think this a viable fix for your broken drive, think our record on clean room and its specification before attempting to have the platters or logic board replaced.

Harddisk Data Recovery

Now, there are some refurbished sites that are mostly in countries such as India or China who promise to fix hard drives back to working condition. The refurbish drives and promise to get the working for years. While some hard drives may last for many years, the chances of a good refurbished drive unmistakably lasting for long periods of time are slim. These refurbishing sites will replace the parts and hide bad sectors give you back a formatted hard drive that is supposedly fixed. While you can take the opening of your hard drive working, you still may lose data. You can use this as a form of data recovery by taking data off the hard disks while it is still working, but no one should expect a refurbished product to last many years. In fact, refurbished disks should be used with the expectation that data recovery will be needed in the near future, so make sure to use a good storehouse backup system.

Replacing platters is just as hazardous as replacing the logic board in a hard drive. Data recovery, once again, needs to be done in a low contaminated room with few particles that can cling to components. Replacing platters is a delicate process that can finally ruin the drive altogether. Hard drive recovery is dependent highly on the tools that are needed to open, repair, and replace components. Most local shops don't have passage to these highly developed technological devices, so it's not possible to fix the platters properly. Other things to think are the firmware and technology that allows the hard drive to read the data on the platters.

When deciding on a data recovery method, use professionals that can recover your data. Once you receive your data, the safest way to keep it stored is replacing the drive altogether rather than parts replacement.
