Data Compass engineers classify that hard drive data loss in these two categories:
Logical drive failure – the hard drive is in working order but some files or data cannot be accessed for logical reasons such as a lost partition or accidental reformatting.
Mechanical drive failure – the hard drive is not functioning. The most common reasons are head crashes and motor failures caused by overwriting, physical damages, natural disasters, and also viruses.
When drives go bad:
o If possible, back up the data immediately
o Do not use utility software if the drive makes scraping, tapping, clicking or humming sounds
o Do not power up a device that has obvious physical damage or is making unusual sounds
o Shut down the computer to avoid further damage to the drive and its data
o Do not attempt recovery yourself on severely traumatized drives (i.e., turning computer off and on, using over-the counter diagnostic tools). This may cause further damage or permanent data loss
o If you’re lost critical data, Data Compass recovery service is your best and safest option
o Never assume data is unrecoverable
Data Compass has successfully recovered data from hundreds of thousands of drives with extreme physical and logical damage. SalvationData as one of the world’s largest research and development department for professional data recovery tool has launched the fourth generation of professional data recovery tool – Data Compass. It has been greatly concerned just right after its first appearance in the market. Plenty of companies all over the world select Data Compass as their upgrade tools. Such as Pc Technologies in the United States, Disk labs in the United Kingdom, Datatrack in UK, Data Clinic in UK, Data Recovery Services in US, Afghan ICT Solution and so on.
Canadian CBL data recovery technology data recovery chief engineer Yimei Cao quoted: “The SalvationDATA Data Compass easily helps me get rid of SA bad sectors which can’t be repaired by other drive restoration products we’ve been using before, because it gives access to user data area directly by using its Analog technology which virtually boots the hard drive SA-independently.
Overseas IT production dealers notice Data Compass’s prospective potentials in the market, hundreds of Europe and US companies have applied for Data Compass’s reseller merely in a month.
Data Compass technology dedicated in data recovery and adopt every improvement, to lead in it.

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)
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 surface of the platter. As the read-write head flies over the platter surface its height is controlled by a thin film or layer of air entrapped between the platters and the slider surface of the read-write head. That’s why we mentioned that one of the functions of the protection layer is to maintain the stability of the flying read-write head: the film of air floats the head over the surface will be generated only when the surface of the platter maintains flat and smooth.
If the read-write head comes into direct contact with the surface 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 making 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 solution 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 successful data recovery: even after you swap the crashed head stack faultlessly, it will crash immediately on power up, making 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 reason 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 maintain its floating status when it comes to the scratch area, but makes directly contact 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 patient drive becomes the point of how to make sure the head passes the scratch area smoothly.
Platter Scratch Restoration Solution
What is Platter Scratch Restoration Solution?
The Platter Scratch Restoration Solution is the unique technology developed 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 multiple fields like chemistry, computer application and physics. It is the perfect solution for the current corner 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 comprehensive capability.
Basic principles of operation:
SalvationDATA Platter Scratch Restoration System includes the following major parts:
1. High precision scratch positioner
2. High pressure cleaner
3. Nanometer filling materials spray arm
4. Master program controller
The system will first clean up the target platter using the high pressure air cleaner; then scan the platter with the optical scratch positioner to locate scratch area and label its size and depth; finally the spray arm contains the nanometer filling materials will fill the scratch area with the donor materials under the management of the master program 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 stable floating status so that data recovery from the good area can be achieved. The scratch positioner carries out analysis and positioning towards the tiny scratches using optical imageology technology; by sending the scan report back to the master program controller, a repairing instruction 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 master program 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 different layers.
As for drives of multiple platters, the system will record the platter alignment by using optical image before separating the target platter from the platter assembly; so that the platter alignment can be easily restored after the scratch restoration. The entire restoration process will be carried out by the master program controller and the full angle robot arms under its control without user’s intervention, ought to be the fastest and safest solution for platter scratch restoration available; what’s more, the estimated price of the system would be around $5,000 only, making it the most adoptable and popular equipment.
Support List
The system includes robot arms and workstations designed for standard platters of 3.5-inch, 2.5-inch and 1.8-inch hard drives of different manufacturers; fully satisfies the platter restoration 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 initial launch day plus 6 months).
A Final Note
What we do using this system is to carry out a padding restoration 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 significance of this solution 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.

Today, computers are an integral and indispensable part of the IT world. No matter what your line may be, finance, education, business consulting and investigation, IT information security, or else. In fact, most people always take it for granted. You should never brag your computer can be failure-free.
The foremost use of computer is data storage. All the data is stored on a physical disk named hard disk drive which is a magnetic layer. And it is more likely to be stricken by a wide variety of reasons, such as a partition lost, system can not access, human mistake (accidental reformatting, deletion), file corruption, power surge, and virus attack, to the worst, these physical level failures typically are head crash, platter scratch, and motor failures caused by overwriting, physical damages, natural disasters, etc.
Sometimes a hard drive has been stricken dead or not working at all without any warning signs, but some other times there may be some clues that something is going bad or amiss. Such changes in performance or sudden blue screens are telltale signs that the hard drive may be on its way to collapse. The most obvious and common sign are clicking, squealing, scraping or grinding noises.
The computer become more involved in our daily life, so the danger of data loss also surfaces.
As most of us have already experienced data loss, it could be frustrated and traumatic, when you finally find your critical data are not able to recover. As a matter of fact, logical failures as I previously mentioned, a data recovery software program can simply work out, but speaking of physical failures, No! Those drives with minor physical failures will need a special equipment to repair hard drive itself or recover data.
Why data recovery software will stop there? The ordinary user-level repeated-read access method that is used by imaging software bring a risk of damaging the disk and head, making data lost irretrievable. Also the software skips bad sectors directly in order not to get hang (freeze). Even so it gets hang most of the time in case the drive has lost of bad sectors. Plus, there is no guarantee that all the data will be extracted as much as possible, though days or weeks of time wasted on imaging bad drives. That’s why you should avoid it at all cost.
A unique data recovery equipment known as Data Compass is mostly used among experts and practitioners worldwide, where traditional tools can not reach the height. Data Compass reads data of each sector physically byte-to-byte, including good and bad, and copy to a good disk using its data extraction software and hardware. “Shadow Disk” technology allows Data Compass to maximally avoid further damage to the drive, and ensure the data is not lost from repeated recovery attempts.
Technically speaking, it is hard to figure out how exactly the data can be recovered. It all depends. In most cases, data will be able to recover as long as the parts of hard drive are not severely damaged, otherwise you should swap its components then like platters, heads, and a spindle motor, for example.
A current tool named “hard drive head/platter exchange professional” used for drive disassembling and head/platter exchange will be replaced by the vendor soon. The change is made for optimization reason, and the new product is a better enhancement; plus, the new platter exchanger allows users to work on hard drive with spacers between platters.
If you have known much about data recovery and if you have a craving for this field, you should start your own business with a right equipment and then you can be an expert. Of course, it is not easy to find a proper option from current data recovery equipments with sky-high price in economy hard times. It is even worse when comes to new versions of software to products you are possessing, vendors will charge every time. In this case, free of charge upgrade service is the way to go.

Previously, in the IT world, most people were focusing on Seagate Barracuda 7200.11 family hard drive and were worry about some drive-level issues, such as hard disk drive status stays BUSY; hard disk drive being detected with 0 in LBA; hard disk drive reports SMART error on startup, etc.
However, all these problems now can be fixed without damaging the data, instead works for data recovery. That will be unique features which are only available in HD Doctor Utility; no other similar HDD repair and data recovery equipment is capable for solution before this time. It’s being a big step.
The problem that HDD being detected with 0 GB is a typical malfunction for Barracuda 7200.11. Such drives can be detected normally but the data area is inaccessible with LBA detected as 0.
Here is an option: the upgrade version of HD Doctor for Seagate 3.0 adds the feature to recover such malfunction without damaging the data on the drive. Also, this can work out for Barracuda 7200.11 malfunction that drive stays BUSY.
How to get rid of CE LOG error from products like HD Doctor?
It was said that when being connected to HD Doctor Console, the malfunction drive can be ready and detected normally, but it will be very slow in reading data from the drive. Some experts clarify that the CMD utility will repeatedly output CE Log error message, which is the reason that causes the drive being very slow in reading data from. The version 3.0 adds the feature of CE Log Repair to remove such malfunction. The feature is intended for Barracuda 7200.8, Barracuda 7200.9 and Barracuda 7200.10 drives.
As experts and professionals worldwide predict that HD Doctor for Seagate is a software-hardware complex designed for data recovery from damaged Seagate hard drives. Its first release was on 2004, since then it was developed from a DOS program that supported the major models of Seagate drives to a software-hardware complex runs on Windows with easy and instantly renewable USB installation. Now it has been the tool supports the most comprehensive drive families; with the problems of Seagate Barracuda 7200.11 being exposed, on this July, solutions have been worked out for three typical headaches mentioned above.
In fact, hard drive storage is not relatively secure. Even the best products can eventually malfunction and any minor repair from a data recovery company can be expensive.
Anytime, most people take their data for granted. Let’s face it! Given your data drive malfunction, you can easily lose all the data on it, even find it helpless till after send to a third party data recovery company. One way of dealing with this impending danger is to do backups, so that you will be able to retrieve your data in a case of a drive malfunction. Don’t get your data risking.

Accidents do happen all the time. Most people have experienced a loss of data. That files could be so important as if you have suffered a personal loss. Hard drive crashes will lead to hardware or software failures. Even to the most severe case, the file system corruption.
Although there is some confusion as to the term “data recovery”, it can also be the process of retrieving and securing deleted information from a storage media for forensic purposes or spying. To be more specific, Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media formats such as hard disk drives, storage tapes, CDs, DVDs, and other electronics. Recovery being processed due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.
Physical damage can be caused by a variety of failures. Hard disk drives can suffer any of several mechanical failures, such as head stack crashes and failed motors; tapes can simply break. Physical damage always causes at least some data loss, and in some cases the logical structures of the file system are damaged as well.
Recovering data after physical damaged hard drives: most physical damage cannot be repaired by end users. For example, opening a hard drive in a normal environment can allow airborne dust to settle on the media platter and being caught between the platter and the read-write head, causing new head crashes that further damage the platter and thus compromise the recovery process. End users generally do not have the hardware or technical expertise required to make these repairs. Consequently, data recovery companies are often employed to salvage important data. Nevertheless, it will also go with the resulting risk of being processed by a third-party company without supervision.
In 2008, Data Compass succeeded in research and development of Mobile Electronic Data Recovery Device which possesses high intelligence and can be easily mastered by a common computer operator, which prefigures that this device will be a must for government departments and companies’ choice of data security in the future. Data Compass not only solved those problems that storage media software and hardware cannot be repaired in the past yet the recovery device is too huge to remove, also help government implement electronic government information recovery under interior transfer, that maximally protect government’s confidential data security through processing in-house and real-time data recovery, generally evade and eliminate government and companies’ fear of uncertain cases under data-level management. It is noted that there are many accounts of users getting a bad disk going long enough to pull their data off, often via slightly bizarre tricks. These include making the drive cold (in the freezer) or spinning it manually on the ground, both actions being used to unstick a jammed media platter. However, most data recovery professionals disapprove the use of tricks such as these, since they can cause additional physical damage to the drive.
Do not attempt recovery yourself on severely traumatized drives. This may cause further damage or permanent data loss.

This is a situation that every tech support person has faced or will face at least once: a failed hard drive. In this particular case, a user was getting errors like “disk 0 error” and “invalid drive specification. “
Here were the other facts in the case:
o The data wasn’t backed up.
o The problem came out of nowhere.
o The user had accessed Setup and tried to manually enter the settings for the drive type when”Auto” didn’t work.
o There was no start up disk made by this machine.
Repair a drive like that one-even if only long enough to copy its data before you throw the drive in the garbage-is a tough challenge. Compared to buy a new drive, the price of Data Recovery nowadays is still a very expensive option.
While the Freeze it, Hit it, and Drop it options are still experimented with by some, the current size and sensitivity of the newer larger hard drives makes these options extremely risky and definitely NOT recommended for hard drives with a capacity that’s greater than 60GB. And even then some of the operation suggested here should be approached with caution. Getting it wrong by trying to save some money will only end up costing you more if you then decide to pass on your hard drive to a data recovery company. . .
There are, broadly speaking three classes of data recovery, Logical, Electronic, and Physical.
o Logical Where the FAT, NTFS or other file structure has been corrupted either by accident or on purpose or individual filed or folders have gone missing. The hard drive has not suffered damage to the components of the hard drive itself.
o Electronic Component failure on the PCB (the circuit board on the bottom of the hard drive) in the motor or internally.
o Physical Internal damage to the hard drive, damaged platters, head crashes, damage to the motor, or head rack signal amplifier. You need a clean room and plenty of experience to have any chance of a successful outcome here.
Logical recoveries are becoming an affordable option for those people who are familiar with the risks involved with data recovery. Software tools that are now available for this task vary greatly in their capability, complexity and cost. Careful research should be done before any work is done on the damaged hard drive. If you are able, get another hard drive and experiment. Format it, Fdisk it, delete files and partitions and learn how the data recovery software operates under these various conditions. Before to start work on your own or your clients hard drive back it up, the backup mantra is one that you all should be familiar with by now! There are tools available to backup (or image) a hard drive that has been fdisked!! Use them. Ghost software is not suitable for this task, then perform your recovery attempts on the image not the original.
For the Electronic damaged, you must need some extra hdd repair tools to exchange the PCB or Head or other components, as far as we know, nowadays one tool called HD HPE Pro produced by SalvationDATA can do the excellent job of exchanging drive’s components. Many data recovery companies now using this tool, also nowadays there are many faked tools in the market which price is lower than SalvationDATA, but with bad quality.
As for the Physical problems of the drives, if the situation happened in several years ago, then even the best professional data recovery company will say that they have no choice.
But nowadays, the HDD recovery tools grows at a quick rapid speed, there are many tools can do this job now, among them the most famous tools are produced by ACE and SalvationDATA, but it is said that the Data Compass of SalvationDATA is much powerful, which can also support the Raid data recovery, which ACE doesn’t has.
So nowadays whether your HDD has logical or electronic or physical damaged, you are no need to worry about your data, because there is always solutions here to find your data back.

Both NOR and NAND Flash memory were invented by Dr. Fujio Masuoka from Toshiba in 1984. The name ‘Flash’ was suggested because the erasure process of the memory contents reminds a flash of a camera, and it’s name was coined to express how much faster it could be erased “in a flash”.
Flash memory is a form of non-volatile memory that can be electrically erased and rewrite, which means that it does not need power to maintain the data stored in the chip. In addition, flash memory offers fast read accessing times and better shock resistance than hard disks. These characteristics give a good explaination the popularity of flash memory for applications such as storage on battery-powered devices. However, USB flash drives are a convenient way to transport data from one location to another. USB have several advantages over conventional data transportation methods including:
1. Compact in design
2. Light weight
3. Low cost to purchase
4. Ever increasing capacities (up to 8GB or more)
Whilst disadvantages include:
1. Higher cost per Gb
2. Slower than conventional hard disks
3. Higher risk of losing data
In general, solid state storage devices such as memory cards or USB flash drives offer greater reliability than their conventional hard disk counterparts as they contain no moving parts. Faults are nearly always related to either an onboard component malfunction or poor assembly. Frequently in order to recover the data, it’s necessary to fault find by tracing the electronic signals in the devices themselves and replacing / repairing the faulty component, or modifying boards / components to create a workaround on the device.
It’s important to remember that if the data contained on the faulty device is of value, and it is necessary to have it recovered by experienced technicians. Data on solid state devices can often be rendered unrecoverablely due to incorrect recovery procedures not being noted.
Typical USB memory stick / card / pen drive failure & data loss symptoms: The device will no longer be recognised by the computer when inserted; or the device will be recognised but appear empty or the device will be recognised incorrectly or show the wrong storage capacity
Luckily there are some professional Flash recovery tools like PC-3000 Flash, which handles all models of flash drives (SD, SM ,MMC, USBFlash, MemoryStick, CompactFlash etc.) But the new giant of data recovery tools provider SalvationDATA will release the Flash Doctor in July,2009. It is said that its functions are more powerful and covers a larger range of support list. Based on the HD Doctor and Data Compass which has helped quite a lot of data recovery technicians, we can give another chance to SalvationDATA to check the fact that new technology brings more convenience to people’s lives.

In the recent past, Information Security has received a lot of attention in the business and trade press. Much of this can be attributed to an increase in security breaches leading to major losses to the affected enterprises, such as Holland bank burglary of large amounts of deposited money. Therefore, Data backup and data destruction are overwhelming topic and concerned widely that any enterprises with large database should take it serious.
As the surge of world web and increasing competition, it is common that enterprise’s confidential documents and personal sensitive data were stolen. Manage to think it through, if the data in the disk hasn’t been removed permanently, and once it was gotten on hand by someone with ill-intention, the consequences will be disastrous. And a thorough disk wipe is a must and ultimate objective especially for government agencies, military who emphasize the thoroughness of data destruction. Therefore, to ensure data security is one of the core tasks of modern enterprises, government agencies and military. Meanwhile high standards were required so as to destruct data permanently.
It was reported that SalvationDATA Technology LLC is about to release a multifunctional disk image and disk wipe tool —-Data Copy King. As the first industrial-level data backup and data destruction tool combining disk image, disk clean and HDD diagnosis together, DCK is exclusive designed for large capacity hard drive with real-time data backup and data destruction transfer rate respectively up to 6.8GB/min and 7.2GB/min. and with 1-999 rounds of data destruction well overtaking the 1-99 rounds by DOD, it is fully capable of thorough data destruction of confidential and sensitive data.
In addition, opposite to data destruction, data backup should be placed the same importance, which is the fastest counter-measure solution preparing for contingencies data. Nowadays most enterprises employ TB level storage devices, to backup such large capacity storage devices, if the employed tool with low transfer rate, it is surely a time-consuming project. While With data backup transfer rate up to 6.8GB/min and targeting to TB-level, it absolutely saves abundance of time.
And the chief engineer form SalvationDATA Technology said, with the excellent performance of DCK, its upcoming surely will spearhead the domestic developing in info security field to a new era.

Seagate has recently discovered that Barracuda 7200.11 family hard drive has a random, unexplained freezing problem that was usually most apparent with hard drive stays BUSY, being detected with 0 in LBA.
There is so much talk about this major problem, some say that if the hard drive powers up, it will be recognized in the system for a few seconds, and soon it shows as “BUSY” “Drive Not Ready”, or LBA is detected as 0.
Technically speaking, Seagate 7200.11 family has a big capacity up to 1.5 TB of storage. Bearing GMR recording heads technology can provide drives with increased recording density; in this case, an error-correction algorithm was made to maintain the read correction and data storage. SalvationDATA experts verify that hard drive will sequently read the data in P-list and G-list, when perform on a detective list. Otherwise, as soon as the read command failed; the hard drive will promptly get into a state of self-protection, so the data stored on the disk will not be destroyed by other operation errors of any time. The reason that can cause read failures is the mess of data in G-list and P-list, and that’s the problem where hard drive are going “BUSY” soon after powered up.
However, there are many solutions out there claim to resolve these problems like hard disk drive stays “BUSY” and “Drive Not Ready”, or being detected with 0 in LBA, for example. In fact, they are simply dealing with the “BUSY” issue. Here are the options:
1. First you need to remove PCB from HDA case and connect it to the console box.
2. Turn to CMD mode, command “Ctrl Z”; “F3 T
