How to recover bad sectors on hard drives

How to repair bad sectors on hard drives

Despite the growing popularity of flash memory, a mechanical reading of the data recorded on the hard drive is. Often, work with this method of surface plates having bad sectors.

And usually they can not be restored, but there are exceptions.


The issue of security on the hard drive information forces developers to think of data storage to the smallest detail. However, in an actual operation of the device, all their tricks do not help.

Why spoil the sector

The principle of operation of the mechanical hard drive is verysimple. There are several circular magnetic plates. According to him "run" read heads and looking for the right information. When the hard drive mechanism is subjected to vibration or excessive shocks, microscopic scratches can occur on the surface of the disc. This leads to the deterioration and loss of data sectors - software, books, music or movies.

How would carefully you may have exploited the PC, the hard disk may still appear bad sectors.

If the hard drive worked for several years, it may disrupt its tightness. Any speck of dust gets inside - it is a potential cause of bad sectors.
Add to this the power surges, sudden shutdown the PC and simply mishandling computer and the reasons for the deterioration of information will be much more.

Is there a way out

If there are bad sectors, it is not necessary immediatelypanic and change urgently "iron". There are ways to either mark the problem areas, so that in the future they do not create problems. Either fix the damage with the help of some special programs.

When there are bad sectors, there are two ways - to use its own system or a third-party program.

The simplest thing you can do - isstart checking the surface of the discs. To do this, right-click on the failed logical partition, select "Properties", then the tab "Tools" and "Check Now" ticking "Scan for and attempt recovery of bad sectors." The system will scan the disk, find the error and either return the sector to a working state, or mark them as bad to read heads pass them by and did not create a "loose" in the work.
For a more "advanced" users canrecommend HDD-Regenerator program. It works on a physical level and helps to cope with the problem where full-time disk check program is useless. Regenerator holds profound work and in most cases, sector returns to normal. You will not lose data and to significantly increase the life of the hard drive service.
There are many other programs, even thosewho are able to understand the only real "hackers", or people with experience. However, in most cases, enough of the above two products. They are time-tested and helped in many complex cases.
