Since the hard disk is individually packaged and shipped to the client for deployment, it will increase a lot of manpower and material resources, and it is not easy to control. Therefore, the shipping method is usually mechanical hard disk installation. Shipped together with the whole machine on the server.
硬盘是十分精密的存储设备，进行读写操作时，磁头在盘片表面的浮动高度只有几微米；即使在不工作的时候，磁头与盘片也是接触的，运输时物流时间较长，加上道路状况、物流公司素质良莠不齐，运输、装卸过程中的冲击震动就容易造成磁头与盘片相撞击对崭新的硬盘造成直接损坏或潜在风险。The hard disk is a very precise storage device. When performing read and write operations, the floating height of the magnetic head on the surface of the disk is only a few microns; even when it is not working, the magnetic head and the disk are still in contact. The road conditions and the quality of logistics companies vary. The shock and vibration during transportation and loading and unloading may easily cause the collision between the magnetic head and the platter, causing direct damage or potential risk to the brand-new hard disk.
