Hard Disk Driver Introduction and Matters Need Attention
Hard Disk Driver, short for HDD, full name Winchester type hard disk driver.It is the main storage device of the computer, and is also what we call the "ssd driver" in our pos machine. Consists of one or more discs made of aluminum or glass. The discs are covered with ferromagnetic material.
Matters need attention for Hard Disk Driver:
1.Do not switch off suddenly while working!It may cause severe friction between the head and the platter and damage the hard disk driver. Turn off the power switch of the computer only after the indicator stops blinking and the hard disk driver reads and writes are finished.
2.Keep out dust!If dust is caught on the circuit board, it can cause the hard disk driver to work unstable, or cause internal parts to be damaged.
3.Prevent too high or too low temperature!The temperature is too high or too low will lead to the change of the main frequency of the crystal oscillator clock, will cause the circuit element failure. If the temperature is too low, the moisture in the air will condense on the element, resulting in short circuit.
4.Avoid strong shocks! Because the distance between the magnetic head and the magnetic sheet is very close, if it is subjected to violent shock, the magnetic head will knock the magnetic sheet, which may lead to the complete damage of the magnetic head.
In addition to avoiding the above problems, we also need to defragment the hard disk driver regularly. This will speed up your hard driver. However, do not clean every three days, this will also reduce the hard drive life.
And finally, anti-virus.
Below I will show you the common types of hard disk drives.
