这里其实可以向大家先说明一点,即使是从厂家出来的全新硬盘,它们的盘片也不是一点瑕疵也没有的。由于磁盘的盘片比较精密,对于生产环境和移动都有非常高的要求,即使是一粒灰尘、一次很轻微的碰撞,都会产生从几个到数以百计的环扇区。所以,一般地,按照现在硬盘120GB的容量,全新的盘片即使有几千个坏扇区也不是不可能的。只不过硬盘厂商会使用专门的设备去扫描盘片,把那些坏的扇区和磁介质不稳定的扇区都记录下来,做成一个硬盘缺陷列表,写进系统保留 In fact, we can explain to you first of all, even from the factory out of the new hard disk, their disc is not a flaw nor. Due to the relatively precise disk platters, there is a very high demand for the production environment and the movement. Even a single shot of dust, a very slight collision, will produce several to several hundred sector sectors. So, in general, with the current capacity of 120GB of hard disk, it is not impossible for the brand new disk to have thousands of bad sectors. Only hard drive manufacturers will use specialized equipment to scan the disc, those bad sectors and magnetic media instability sector are recorded, made a list of hard disk defects, written into the system to retain
