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.

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.
