What is bad sectors? Recognize the hard drive is bad

Things to know about bad sectors

When the computer is running, an error message appears bad sectors, Common errors "CRC" or "Cyclic Redundancy Error". Some data files are lost / damaged, illegible, and never can access files / folders. Sector is the subdivision marker and ID number of the hard drive and when bad sectors means that the data can not be written or read by physical damage or other fruit of parity check the bits on disk. Any data that is recorded or stored in areas that are damaged or lost / error. Data on the rest of the disk can not be affected if bad sectors are mild cases

Bad sectors are mainly due to weakening of the magnetic domain and the error. In the time since the loss of magnetic disk therefore not capable of holding data. Error on the disc include physical shock, and sudden power outage interrupted during reading record. Readers also crash at the bad sector condition leads to permanent data loss and sometimes bad sectors as well as the parity bits are encoded, failure / error. In this case, the Institute for Computational tools are exclusive to repair bad sectors without losing data by repairing or rewrite the parity bits on disk
Signs:
Drive slow, time consuming file access or inaccessible. In severe cases, the entire disk becomes inaccessible.
Cause:
- All hard drives are prone to bad sectors in harsh operating conditions due to high temperatures, vibration, mechanical movement of the Actuator or user-caused collisions lead to reader bounced on the surface the disc.

- According to research by laptopdrcare, lubricant inside the motor, due to the high temperature of the environment has evaporated escape, having lower temperatures should freeze the material particles, collisions and damage the disk surface.
- High-temperature environments of computer use causes performance degradation of the magnetic surfaces.
- Faulty power or reset occurs during the read / write data.
Do not:
In all cases, you should not try to use Scandisk or Chkdsk utility to run because it can not repair the damage repair bad sectors, but also makes the data difficult to recover or worse, lose data permanently.
What should you do?:
