数据恢复全解析（Data recovery full resolution） Data recovery full resolution.Txt I envy some older people who envy them hand in hand until the last.. - pay the bill when they found themselves so valuable. Data recovery full resolution Todays world has completely entered the information age, in our daily life, more and more things are being expressed in the form of 0 and 1. The more closely connected digital technology is to us, the greater risk it will take when it fails. Once the important data is destroyed, we suffer huge losses, so the data recovery industry emerges as the times require. Save the data recovery data in data loss and damage, according to a variety of hardware and software platform to carry out, removed from the file storage device error, seriously damaged, professional data recovery work can restore the data. In this article, we will introduce all aspects of data recovery, and give some suggestions based on our experience, in the hope that we will be less troubled by the loss of data. Principle of data recovery technology This work covers a wide range of data storage, and different storage media will have some differences when performing data recovery, and the reasons for data loss or damage are not the same. We explain the object oriented mainly magnetic storage media, such as hard disk, floppy disk and data tape, and so on. First of all, we need to explain the principles of magnetic storage technology, which will help us to better understand the data recovery work. Magnetic storage technology works by changing the polarity of magnetic particles to record data on magnetic media. When reading data, the magnetic head converts the polarity of magnetic particles on the storage medium into corresponding electrical pulse signals and converts them into data forms which can be identified by the computer. The same is true for writing operations. To use data files on media such as hard disks, you usually need to rely on the file system functionality provided by the
