Data recovery is a term used to describe the process of extracting the data storage medium. With the recording device, and do not just mean, the obvious devices, such as internal hard drive, external hard drives, memory sticks, CDs and other electronic storage of data is usually associated with computers, but also not so obvious devices, such as a hard disk into your sky box or a hard drive camcorder.
When data is damaged or destroyed by other means, it may be that we can play half a song, we see half of a picture, watch a movie, but has no image or just an explicit error message saying "can not open file" or something similar. Recovery of data is not easy and if we try to do our self, we may need to become familiar with the term "hexadecimal editor" because it allows to view the file one byte at a time, and by comparing the bytes of a good "file", we can copy and paste them into the "bad" files which makes it correct - is a minefield! Since recovery of the data is so specialized, on average, people do not really themself, but choose to use recovery of data service (there are a lot of the line) that can be expensive - it depends on how valuable the data loss is to the individual.
It is the process of searching for parts damaged or inaccessible hard disk information computer system. The recovery can be a primary, secondary, or a temporary storage device. The data recovery software is typically used when the hard drive is physically damaged or some of the areas of logical errors on the hard drive. With the help of this software, we can re-obtain and safeguard the personal information we have removed.
Methodology:
Recovery of data after physical damage:
The physical damage caused by the read head on the hard drive does not respond or damage may have occurred in the metal layer of the compact disc. The most simple and quick way is to replace the affected parts of the hard drive. This can cause errors in the logical drive, new parts are installed. There are some useful techniques to recover data in these cases.Virtual disk:
Creating a virtual disk may be conducive to the reconstruction of any lost data. Images can be converted into a usable form. The action can remove the physical damage.
Recovering data after logical damage:
Logical damage is more common than physical damage to the hard drive. It usually occurs due to power failure resulting in non-expected unsaved data or incomplete back to the previous state. And when the same data / file is still used, a gap appears in the system that leads to serious system failure.
Precautions:One way to prevent such damage is the use of reliable file systems such as EXT3. This system is designed so that even if the power fails, it will reduce the file in a consistent state. A backup power system can also help in case of persistent failure.
State analysis:
The analysis of each area of a file system with the control, un-veil the logical error, and you can correct mistakes in time and before they turn into big problems. This activity takes time and can be costly in the short term, but long-term financial and non financial benefits.
Thus, a process of data recovery can retrieve important data which lost due to damage
The repetition of Fame will give us a free initial consultation and follow up with a detailed analysis of the training, along with a budget of cost recovery. These should also be free if we choose to recover the data, the process must be conducted in a room specially designed clean air control. The recovered data can be returned in the middle of their choice, including CD, DVD, hard drives or flash memory.
