The hard drive of your computer is full of sectors. This is where all the information we store on our system are recorded. Some areas may have suffered permanent damage. They are about as bad sectors. Basically these are the areas that caused some damage and can no longer write. You can easily detect bad sectors, software, system utilities such as CHKDSK or ScanDisk (Microsoft) or badblocks (Unix systems). They are marked as unusable by the programs and the operating system can not record information about them. The operating system saves data to a new location, or rather a new area.
Problem:
When the system detects bad sectors, it usually means you do not have spare sectors that can write data. This means that computer memory is low. In short, this means that when you want to save the information, the computer will take some time to understand where to save the data. However, one must remember to take backup data as soon as they are of bad sectors. It is just a precaution as bad sectors cause corruption of files system . This causes a slow rotation of the computer and ultimately stop running. Sometimes you may find the following error messages: CRC" or "Cyclic Redundancy Error".
When these areas are bad, there are 2 problems for people.
The information is already saved will be lost
The memory of the system begins to reduce.
Solution:
You cannot fix bad sectors. But running a scan can in a way 'inform' the computer about them, so that the operating system does not store more data in this field. They can follow the instructions to do this themselves:
Click the Start button.
Select My Computer.
Under disk drives highlight the disk you want to analyze.
Open the File menu and select Properties
Open the Tools tab
Click Check Now
In this way, the hard drive scan locates bad sectors and mark them unusable. But if you have already lost your data or bad sectors on your computer will not boot, contact Data Recovery Services (DRS). They have trained hard drive recovery technicians.
