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. When it comes to the data recovery, we have to mention hard disk data structure, the document storage principle, and even operating system startup process, these are your the basic knowledge when your want to recovery hard disk data. Even if you don't need to recover the data, to know that these knowledge (even if it's just a little bit more know some), but for your usual computer operation and application is also helpful.

The principle of data recovery, a lot of people feel strange for data recovery, some people feel very afraid for data loss, but sometimes didn't imagine that too terrible, if you can look down from above, if you know the structure of the hard drive you will find that, our data saved to a storage medium blanks, when we save data, will be in the blanks on bumpy and store the data. If we delete the file, and we have not put all the bumpy out of the medium, but address, and let the operating system can't find this file, and think that it has disappeared, can be in this place to write the data, the original bumpy data information to cover off, so the principle of data recovery is not covered, we can use the software, the breakthrough operating system addressing and addressing way, to find those who are not covered parts of the data and form a file, if several small place are covered, can be used to correct the mistakes, So we advocate if found that file is missing, immediately find data recovery companies to recover, don't do any operation!

Data recovery successful advantage

When your data is loss, if looking for data recovery of the company for help, and retrieve the data from the hard drive back out, but there is a lot of people will find that the data he wants have been destroyed, and not important data and can find out, and those still WORD, EXCEL and finish to find isn't open, and bad, why? When we put the hard disk points good area, establish a folder, save data, so it will determine the data position, although the division is logical, does not necessarily in a royalty a place, but we save, writing, and reading data, will find that place and then find out the data, so when we write data, time is long, the place to read more is the head of the laser light and strong fever deformation, lead to the destruction of the data. So if you often block of data backup of words, so data saved to the other place and can not damage the hard disk and restore a good data out!

Hard disk data recovery is very famous data recovery software. The software function can be said to be very strong. No matter what deleting is a mistaken or format or go back after the division of data loss, it can be easily solved, it can even don't rely on partition table to cluster to scan in accordance with the hard drive. But take note not through the partition table for data scanning, probably will not be fully recover the data, the reason is usually a big documents are stored in a lot of different regions within the cluster, even if we find the document data on some of the cluster, is likely to restore the file is damaged. So this method is not everything, but data recovery software give us a new data recovery method, suitable for partition table seriously damaged the use of other recovery software can't restore use.

First let us know the hard disk, now the hard disk properties and principle is almost the same with the old phonograph, when we put the hard drive electrify head started from the edge of the plate into blanks, Another destruction of hard disk is: perhaps someone will find, the above situation, the head of the edge of the plate is to begin to spin, to a high-speed rotating speed in the blanks for above a certain height in rotation, when close stops, it has to come back on the edge of blanks at a certain speed back! If so, when we operating computer, if mandatory shutdown, suddenly loses power, then head because voltage instability to return to the edge of the plate and fell to damage the blanks of the concavo-convex medium, and damaged the blanks, time is long, it will destroy the data structure, and in the end, and can't detect hard drive!

"we can put the robot as person, but we still need to expand equipment automation equipment." Robot technology work including: research and development, maintenance and repair. Experts will be in vertical market exploration related the use of technology. For example: some robot experts may focus on health care and rehabilitation center facilities, and other experts will invent equipment for disabled person or for the children's learning tools.
