Introduction to the principle and method of hard disk data recovery

Hard drive data loss common causes:

1, software failure

Common software failure has virus infection, wrong format or partition, mistake clone, delete or overwrite, hacker software man-made destruction, 0 track damage, hard drive logic lock, power off when operation, accidental electromagnetic interference cause data loss or damage, system error or paralysis caused file loss or damage, etc.

Software phenomenon is generally shown as operating system is lost, can not start the system normally, disk read and write errors, can not find the required files, files open, file opened after garbled, hard disk is not zoned, prompted a hard disk partition is not formatted.

2, hardware failure

Hardware failures include disk scratch, head deformation, magnetic arm breakage, head amplifier damage, chipset or other components damage.

Hardware failures generally show that the system does not recognize the hard drive, often a "click click" of the magnetic group impact sound or motor does not turn, power after no sound, the head will not be allowed to cause errors in reading and writing.

Whether it is a software failure caused by data loss or hardware failure caused by the problem of data loss, as long as the lost data is not damaged or covered, through a certain professional technology, we still have the possibility to safely retrieve data. Here to introduce a professional hard disk data recovery software, it can solve the common software failures in the data loss problem, for everyone's data security brought security.

The top data recovery software is a powerful, easy-to-use data recovery tool that restores data such as accidental deletion, incorrect formatting, partition loss, repartition, or partition hint formatting. The software uses the latest data-scanning technology, read-only from the bottom of the disk from the original sector data, in the Advanced Data analysis algorithm, after scanning the lost directories and files in memory to re-establish the original partition and the original directory structure, the entire recovery effect is excellent.

For hardware problems, we recommend that you direct the hard drive to the professional recovery agencies for recovery, such as the Shanghai Day Shield Data Recovery Center. As long as the hard disk data protection integrity, I believe that users will be able to safely retrieve all the data!
