如果您是一个疯狂的DIYer那么您一定想知道硬盘除了转速、缓存等这些常规的规格之外,还有哪些不知道的秘密。现在我就向你讲述这些“鲜为人知”的秘密!硬盘真的是完全密闭的吗? 如果我跟你说现在的硬盘内部其实跟本就不是真空的,而且布满了灰尘,你会不会吓一大跳?这几乎和所有教科书上对硬盘原理的描述都有很大的出入。但确实是经过我自己亲身实践的,如果你对这些有兴趣,就请接着往下看。如果你注意观察硬盘,就能在任何一块硬盘的盘体上(通常是没有电路板的那面)看到一个小孔。这个孔的名字叫“呼吸孔”,它的作用是平衡盘腔内部的气压。硬盘开始转动后,磁头臂电机、主轴(磁盘)电机转动以及盘片和盘腔内空气摩擦,都会产生大量的热量,从而导致盘腔内气压升高。此时,如果不 If you are a crazy DIYer then you must want to know the hard drive in addition to the conventional specifications such as speed, cache, what do not know the secret. Now I will tell you about these “little-known” secrets! Is the drive completely closed? If I tell you that the current internal hard drive is actually not a vacuum, and is covered with dust, would you not Will scare? This is almost all the textbooks on the principle of hard disk are very different from the description. But it is actually after my own hands-on practice, if you are interested in these, then please look down. If you look at the hard drive, you can see a small hole in the body of any hard drive (usually the one with no circuit board). The hole’s name is “breathing hole”, its role is to balance the pressure inside the chamber. After the hard disk starts to rotate, a large amount of heat is generated by the rotation of the head arm motor, the spindle (disk) motor, and the friction between the disk and the air in the disk chamber, resulting in an increase of air pressure in the disk chamber. At this point, if not
