Along with fast development of information in 21st century, computers have been applied to commercially and individually aspects with a remarkable growing speed. So it makes various electronic information, namely, the data – - become important and valuable property which cannot get lost both for enterprises or individuals. How to guarantee the integrity, usability and security of storage data has then become a crucial question day by day. As we know, data recovery can be category in to 3 levels Level 1 Logical Data Recovery. Applicable for Hard Drives manifest itself as following symptoms: Partition Loss, File corruption Virus Attack, Accidental Disk Format, File deletion… Of all the levels, this is the most widely performed. However, according to the relevant reports only 20-30% percent of all the data recovery cases can be addressed using software tools alone. On the other hand, if software tools are applied alone the risk of losing user data increases significantly, which undermines any professional data recovery level. Recovery Time = 1 Day Price = $375-$550 Level 2 Firmware and bad sector Restoration Disk manifest itself as follows 1. HDD is identified incorrectly. 2. HDD starts the motor and then hangs. 3. HDD capacity is identified incorrectly in the BIOS, usually less. 4. HDD can identify correctly in the BIOS, but all sectors are displayed as bad sectors, or disk partitioning is impossible. 5. HDD is very slow in reading/writing/formatting. Recovery Time = 1 – 2 Day Price = $650-$1100 Level 3. Hardware or mechanical data recovery This level handles with hardware component issues which can’t be repaired but the only solution is to have the components exchanged using donor parts. Strictly speaking, Level 3 is part of Level 2: Firmware and bad sector Restoration. Such as Head stack problems, Spindle motor problems and Platter Alignment & spacer problems Recovery Time= at least 2 day Price= at least USD1000 A lot of data recovery companies focus on Level 1 and Level 2 data recovery, but not Level 3. Why do not they want to dig gold form Level 3? The answer is very simple, they consider that Level 3 hardware or mechanical data recovery is too hard to deal with. Actually, it was a challenge problem for all the DR experts in a few years before. Except we have to invest hundreds of thousands money into this field for establishing a class 100 clean room, technique problems can not be overcome. For Head stack problems: how to dismount the head stack and then reinstall properly without damaging the sensitive heads is the key. Spindle motor problems: only a few top professionals with plenty of practical experience can handle spindle motor problems Platter alignment & spacer problems: so far they are still a headache for most of us without proper tools However, since a few professional data recovery tool providers researched and develop into this depth level, some easy to use and cost effective tools was launched successfully and have been gaining a popularity from DR experts, IT technicians and Forensics. The tool can assure you to operate on your HD on a relatively stable table, making your job easier and more reliable. Also, maintains the original cylinder status by removing and placing each platter of the multiple platters together, so that allows you to change multiple platters without moving the platters out of alignment with each other which otherwise will result in data corruption. Class 100 clean room can provide a good environment for drive disassembly and head/platter exchange. But it is not absolutely indispensible. This job also can be done successfully in a closed clean space. If you want to know more about data recovery hardware, please go to Google search.

The Necessity for Data Recovery Training

With the increasing of data loss, people are commonly suffering from economic loss from this catastrophe. Data recovery is highly urgent and required for people in all walks of life. Due to the variety of data loss reason and the failure of hard drives, data recovery works vary and the charge for every data recovery is different. Even, logical data recovery and physical data distinguish a lot. As data recovery is more and more popular and lucrative presently, more people are beginning to expand their business or start their business in data recovery field. But, how to do data recovery data well and guarantee the customer’s data will be the question for everyone who is in data recovery and who wants to enter into data recovery. The solution for this is to take part in professional data recovery training and learn the expertise from one professional company.

As we all know, data loss can be caused by two reasons—logical problem and physical problem. Therefore, data recovery training can also be divided into two types: Logical data recovery and physical data recovery.

It’s a fact that these days more people are capable of recovering their data from drives with logical problem, such as, partition loss, MBR Damage, accidental deletion, virus attack or accidental format, etc. As these problems are very easy to handle, data recovery experts can easily fix this problem by downloading the free software online or using their home-made logical data recovery software. Even, users are well educated with information freely flowing over the internet as well as software which provides an easy point and click interface or even a good set of instructions, no need to send their drives to the data recovery service company. So, when we meet some companies advertise data recovery as a prime service, we must think about this and make a wise judge on whether they are providing logical data recovery or physical data recovery. Because most of the service they are advertise is recovering the data from logical failures. When it comes to the physical problem, such as hard drive clicking, bad sector, and drives cannot be detected, etc, and the logical data recovery tool cannot solve this problem, then some of the experts of customers will go to the next level and outsourcing. When outsourcing occurs the data is usually passed to a third party and the service provider must make sure that they can highly protect the customers’ data and ensure the data recovery successful rate. Then how to ensure the data recovery successful rate and protect customer’s data? The answer is to take part in the professional training.

Data recovery training courses instruct you on how to diagnose the defective drives and revive dead hard drives and extract data from drives that are in logical or physical problem. Data recovery training also instructs you on how to recover RAID arrays, flash drives, zip drives and exchange servers.

After data loss, you should never run any disk checking tool or disk de-fragmentation utility. It might destroy your important data and could make it impossible to recover. Data loss can not be accepted at any cost and it needs to be fixed as quickly as possible.

Data Recovery software are extremely powerful tools and can recover your precious data from variety of data storage media like hard drives, USB drives, CDs, DVDs, flash drives and so on. Data Recovery Software are helpful in the majority of logical data loss situations.

How data recovery software work

To find out the most excellent Data Recovery software, you must know the way in which computer stores data. The computer file management system consist of two different parts:

* Data area

* System area

The data area is used to originally store data, whereas the system area is employed for storing information, which maps where the original data is stored on the disk in the index table. When user deletes a file, the operating system just marks the pertinent portion of index table free for reuse.

The actual files are never deleted from the hard drive and can be recovered until they overwritten. Hard Drive Recovery software use powerful algorithms to scan your storage media and recover lost or missing files.

The better Data Recovery Software that can effectively and easily recover your lost data offer free demo versions. The demo versions allow you to see the amount of recoverable data and check out the workings of software.

Solution to SSD Data Recovery

roger — Mon, 03 May 2010 00:48:08 +0000

It is true that state disks (namely SSD) are prevalent and becoming an important presence on the storage market, and almost any worth-mentioning notebook manufacturer offer its customers with a SSD option. if the SSD market reaches the levels of penetration predicted by many analyst , then in a handful of years nearly half of all new notebook PCs will use flash SSDs instead of hard drives. The reasons for the aforementioned trend are due to the great advantages of SSD Drive itself. SSD always refers to the drives which physical components doesn´t include any moving parts like spinning platters, moving heads etc. While consist of flash memory chips. These hard drives use special kind of semiconductor devices with erasable, writable cells. The advantages of the SSDs over conventional hard drives are that they are extremely fast, since they do not use moving parts during the read/write process. Moreover, they are shock-proof as well as less power consumption. It is said that there’s a high chance the SSD will work well even after it has been dropped from the top of a two-level building.However, in spite of having no mechanical parts in SSD, these drives are also not completely secure from failure. Similar to hard drives, the cause of drive failure to SSD also can be classified as two types: Physical failure and logical failure. Physical failure in SSD occurs usually because of power failure and magnetic fields problem; while logical failure occurs mainly due to human error and virus attack. All these will be the fatal led to data loss. So what will be your solution in case your solid state drive has encountered such a catastrophe and the eventual loss of data?Do not be panic to worry that your data can’t be recovered again as you can find the solution soon when you arrive here.For logical failure, as you might know, a couple of logical data recovery software cab be capable to tackled this problem easily and recover the data finally from the faulty SSD.However, Data recovery software solutions are not capable all the time. Supposing that it comes to the case that your SSD suffers physical failure and cannot be seen in the PC again and the logical data recovery software never work now. In this condition, you must adopt other solutions.Regarding Physical failure of SSD, we found that there are currently not too many SDD recovery tools in the market and it is proved that most of them are not effective. In the market, some data recovery tools may support most of the HDD manufactures, so it was relatively easy to recover data despite of the factory of the affected disk. However, this kind of compatibility will not be effective again for SSD. Due to the different Wear-leveling and other types of performance-boosting algorithms have made each disk unique, built on very complicated controller technology. In this condition, many people think that Physical failure of hard drive can only be handled by sending them to a professional data recovery center as various methods are adopted for data recovery from the damaged SSD depending upon the cause of failure like in the case of short circuit, IC is replaced with the new one and hence data is recovered.However, SalvationDATA will not reach the consensus that the recovery center is the only solution for data recovery from SSD. As we all know, SalvationDATA is a data recovery tools and technology company headquartered in Sichuan, China. Since entering the data recovery market in 2002, SalvationDATA have developed in-house technologies for recovering data – even from severely damaged hard drives and provide multiple solutions for people in data recovery and forensics and in different level.

What’s the role of data recovery software?

roger — Sun, 07 Mar 2010 21:54:45 +0000

In present data recovery field, Data recovery software has been used widely and do not require professional knowledge. It is also can be produced easily. We can see there are many home-made data recovery software created by IT companies, computer shops even some data recovery amateurs.

It’s just because of the abundant supply, data recovery software has price advantages, they are usually very cheap or even free to download!

Who are using data recovery software?

Only if you are able to use your computer well and have some basic knowledge of hard disk, you can use data recovery software to recover some data for some simple cases. If you know further about firmware and data storage theory, you can then use some data recovery software with advanced features to repair bad sectors, firmware failure, etc. Data recovery software is often downloadable if you buy and get the authorized ID and password or license key. For this issue, data recovery software is quite popular for University students, data recovery amateurs, small data recovery companies who have very limited budget and target at some logical data recovery market, SOHO data recovery studios, etc.

However, if you step into further, you will know that for a complete data recovery process, the sole software is not enough. For example, you have damage in PCB or heads; you need to swap them from a donor drive. After the swapping, does it mean your drive is live and you can read the data? In most cases, this is not true. Even if you exchange the heads, you cannot read the data from your PC, and then you need professional data recovery software to scan and extract the data to a good destination drive. So far in the data recovery market, the best choice for professional data recovery companies are data recovery equipment which are data recovery software and hardware complex tools, such as SalvationDATA HD Doctor Suite, Data Compass, Flash doctor, ACE PC3000 UDMA, DE, PC3000 flash, etc. Because, for professional data recovery companies, computer forensic solution providers and all data recovery related service suppliers, data recovery software only can perform very little for them.

Therefore, in order to work well in data recovery field, to choose data recovery software or not is based on how far you want to involve in this field. The key is how to choose the best data recovery software! We usually have the following Criteria for Judgment:

1st, whether this data recovery software meet your current needs?And can it work stable?

2nd, Compare the price and functions from different data recovery software providers;

3rd, whether this software provides upgrades, is the upgrade free or not?

4th, whether this data recovery software supplier provides technique support, free or not or how long?

5th, Read their end user forum posts and find out how the existing users are using them;

6th, you can test by sending emails and ask questions to the suppliers and see how you will be treated

Is data recovery software enough if you want to start data recovery business?

No, Never enough! As stated above, professional data recovery companies and services providers use data recovery equipment, they may own some free or home-made data recovery software, but in most conditions, only data recovery hardware and software complex equipment can help their work. They even have different tools from different manufacturers. So if you do want to start your data recovery business, you’d better find out data recovery tools manufacturers who can provide comprehensive data recovery equipment and services, these tools usually contains data recovery software and hardware together. So far as we know, SalvationDATA and ACE tools are the best two options for people to start their data recovery business. Except Criteria for Judgment to choose the best data recovery software, you should also ask the suppliers how they will handle the shipping and tax cost for you, in some countries, the tax is terribly high! This is important to understand! Investment is also with the hope of future profit. So if you want your investment on tools to bring your future fortune, please take a good consideration of software and hardware-software complex. Compare the work performance, and then you will work out a good decision.
