24 hours of non-stop servers, the greatest pressure than the hard disk, 24 hours in an uninterrupted read and write state, and the server has the highest rate of bad parts, but also the server's hard drive, then the problem has arisen, the server hard drive is used for a long time, then There may be a variety of problems, and server hard disk "bad sectors" is the most common problem. If during the replacement warranty period, you can bring the hard disk back to the supplier for replacement, and what should you do after the three-guarantee period?
 
Turning things on the hard disk slows down or even dies, and then these phenomena will increase over time in the following period of time; occasionally there will be creaking; files that are saved in will sometimes go wrong or be lost; now you're better off Hard disk detection tool to detect
 
How to use properly to reduce the occurrence of bad sectors?
Using the server hard disk correctly is the best way to reduce the occurrence of bad sectors on the hard disk and improve the service life of the hard disk.

1 server hard disk can not be suddenly shut down at work
When the server hard disk starts to work, it is usually in a high-speed rotation. If we suddenly turn off the power midway, it may cause the head and disk to rub violently and damage the hard disk, so we must avoid sudden shutdown. When shutting down, be sure to notice whether the hard disk indicator on the panel is still blinking. The power switch of the computer can be turned off only after the indicator light stops blinking and the hard disk is read and written.

2. Prevent dust from entering
The damage of dust to the hard disk is very large. This is because in a dusty environment, the hard disk can easily attract dust particles in the air and accumulate it on the internal circuit components of the hard disk for a long time, which will affect the heat of the electronic components. Dissipated, causing the temperature of the circuit components to rise, resulting in leakage or burning of components.
In addition, dust may absorb moisture and corrode the internal electronic circuits of the hard disk, causing some inexplicable problems. Therefore, the dust volume is small, but the damage to the hard disk must not be underestimated. Therefore, we must maintain environmental hygiene and reduce the amount of airborne moisture and dust. Remember: General computer users can not open the hard disk cover by themselves, otherwise the dust in the air enters the hard disk and scratches the disk or head during read and write operations of the magnetic head.
