Solid State Drives (SSD) are now replacing hard drives (HDD) and a good example can be positioned in the wide range of options we found when we buy a new laptop. The elections are now also desktops.
Although the choice between notebooks and solid state drives are available, but demand for laptops are gradually overlapping SSD hard drive over time shows that the solid-state drive (SSD) has managed to lead the market in near future. And with that, data recovery for hard disk is more complicated and expensive due to data recovery for SSD is a complex process and the cost is likely to be higher than previous versions of hard drives.
On the other hand, many users are still unaware of the true difference between these two drives and their advantages or disadvantages. Although we found several storage units every day but do not ask if it is a solid state drive (SSD) or hard disk drive (HDD). I do not wonder that people are not aware of data recovery and its vast possibilities, even the units destroyed and the dead. I did not know about data recovery until it completely broke my flash drive and lost all my pictures from high school last summer.
Well, if you are among those who have not had such tragic stories of lost data or do not know if data recovery is possible even from the dead storage devices physically or logically, I suggest you then become familiar with your device storage and retrieval something, if you use storage units, they are always a likely victim of data loss.
• Hard disk:
Hard disk is a closed disk containing one or more metal discs for storing data. These units are volatile by nature and have an ability to store digital data encoded on the disc rapidly rotating magnetic. Although these dishes are made of glass or aluminum alloy, but we can find a thin layer of magnetic material used on the surface of the dishes that will help in the process of data storage.
Hard disk drive (HDD) were introduced in 1956 by IBM as a data storage device with a simple reason to keep their books, but later the need for huge storage device and reliable hard drive leads to this simple in the complex and advanced as RAID, NAS or SAN, etc.
The undeniable need for massive storage devices among business organizations and individuals not only forced the industry to produce computer storage devices with great flexibility and huge storage capacity, but also had to find a better clarification in the case of a sudden and unpleasant malfunction or loss of data. Therefore, the data recovery companies such as: eProvided emerged in the solution when data loss occurs.
Features hard drive:
• The hard disk drives (HDD) for moving parts such as rotating magnetic platters and moving heads that make HDD weak or sensitive to any physical barrier.
• Plates used in hard disk drives (HDD) are coated with magnetic materials. Therefore, should not be exposed to high magnetic fields.
• hard disk drive (HDD) require more energy to operate, against SSD.
• In hard disk drives (HDD) for searches of computers around the disk data in particular rotation, which can be time consuming.
• hard disk drive (HDD) are cheap and affordable.
• The mortality rate, speed and reliability is low on hard disk drives (HDD)
• Data Recovery (in most cases) simple and easy.
• solid state drive:
Solid State Drives have been marked as a memory device has revolutionized the field of IT industry and lovers of data storage. The unit is still non-magnetic and optical, but not a semiconductor solid state promises faster access to better physical flexibility in extreme temperatures, shock and vibration unnecessary physical.
A solid state drive is a high performance plug-and-play storage device with no moving parts and contain DRAM or Flash memory facilities are designed to withstand physical shock and vibration unnecessary to provide a worry-free performance even in a uniform.
These SSDs are designed with a CPU to manage data and are incredibly faster than other rotating hard drives. Therefore, it is highly recommended for server systems, where time is crucial.
Characteristics of the SSD:
• Solid State Drives (SSD) have no moving parts, is flash memory chip (NAND wafers) and therefore have less chance of physical damage.
• No moving parts there is less energy than does the battery life.
• Solid State Drives (SSD) are not damage by magnetic fields.
• In Solid State Drives (SSD) of computer data can be lifted immediately instead of looking around a rotating disk.
• Solid State Drives (SSD) are more expensive compared to hard drives.
• Compared to hard disk drives (HDD), drives (SSD) have lower mortality rates and are more reliable.
• Recovery of data is complicated in SSD.
Data Recovery Drive (HDD) and drives (SSD)
Data Recovery Hard Drive (HDD) and drives (SSD) can be classified into two categories: Level I (physical failure) and Level II (decision logic). No matter if your storage unit HDD or SSD, if you need data recovery solutions needed after Level I or Level II data recovery.
Data recovery for hard drives is easier and takes less time. So, SSD, due to the complexity of the processes of data storage the most advanced data recovery is difficult and sometimes impossible. The main difference is that the reader board based on the standard can be recovered by mechanical means, while the SSD require a particular technology and an algorithm for understanding individual memory chips and software to try to reconstruct the data.
According to readers eProvided, HDD (HDD) with more than 500 GB can take a few hours or less to recover, while 64 GB SSD can take more than 24 hours.

• The logical damage (Level II):
Logical damage is often caused by power problems (power loss too much and too little, surges, etc.), as this prevents the data and structure of the file system is completely written in the storage medium. A physically damaged storage media may also lead to similar problems. Meanwhile, the file system remains in the storage unit in an inconsistent state and needs appropriate support data recovery to restore and restructure the data.
A malfunction of some that can be displayed on your storage media after the damage logic: information drives the negative amounts of free space, directories constantly recurring, the behavior of clicking on your hard drive is read / write head, etc.
• Physical damage (level I):
The data recovery unit for the physical damage has no solution, then the need for a data recovery company. However, there are still many ways to avoid such accidents. Physical effort on a hard drive (HDD) can lead to big problems, then the SSD (SSD) and this just makes the process of data recovery more complex.
Data Recovery Solid State Drive (SSD): eProvided
• The logical damage (Level II):
Recover Data for Solid State Drive (SSD) has always been a complicated process. A logical drive damaged or cracked solid state (SSD) has some possibilities with the software data recovery, but there are some risks.
Many well-known companies data recovery argued that the use of software data recovery free illegitimate can harm your data storage device and its severity.
Moreover, a recent market survey showed that the data recovery software is designed for drives (SSD) is generally ineffective and inadequate. Therefore, it is best to consult a data recovery company like eProvided then the risk of their data and the duration of the unity of life and integrity.
• Physical damage (level I):
Solid State Drive (SSD) of the demand for device manufacturers can continue to operate even after a fall at two levels of buildings, but this is not true in every situation. A unit of physical damage the solid state (SSD) has, in most cases, a clear need for a data recovery company and experts as eProvided.
A unit of physical harm involving various recovery techniques. These techniques are performed according to the instability of physical disks and physical damage. Some collections are a little easier with a well-established data recovery and spare parts are available in the thousands.
eProvided is about 100,000 pieces in the hand and the reservation is growing every day. Specialized imaging techniques are used to record each bit of experience and deep readable piece back cover of each and a zero on the unit, including error checking.
Therefore, techniques for data recovery and the cost can vary, and some units are eProvided seen in more than 15 rooms, with NAND chips cracks also in more than two parties, with the successful recovery of data is possible. eProvided founder Bruce Cullen states "We are also developing a process for the interior of NAND chips and put them back together internally at the microscopic level" Therefore, the use of data recovery software on the hardware is physically damaged rarely successful, so it is best and should consult eProvided and recovery experts SSD / HDD.
Techniques for recovering data from a logical drive Injured:
• Check consistency:
Process of verifying the consistency refers to the storage media is subjected to a thorough analysis software. This process is done carefully, with the help of advanced software that allows a consumer to know the logical structure of the disc and the accuracy of the directory and its entries. In each set of files in a directory must have at least two basic inputs, such as an entry point that points to itself and an entry point that leads to both parents. The software allows to read and correct any problems that may arise and necessary restructuring of the data.
• Data Size:
When retrieving data from the data storage device in a way no normal size techniques are used. This is because the desired data has no information file allocation system to identify areas or groups belonging to files or data.
Size data often searches through raw sectors looking for signatures of specific file you want, because the file system has no information about the file size being carved, the Current methods include specifying a data block size to "sculpt" to find the desired signature.
