数据恢复中硬盘故障排查实验的设计

当今大学教育除了强调理论知识的教育外，越来越重视培养学生的工程和动手能力。文中针对电子科技大学《系统与数据恢复》课程的本科教学，设计了一个硬盘故障排查的实验。在实验中，首先，对学生分组，让学生熟悉相关的实验设备。了解硬盘故障的分类和故障原因，包括逻辑故障和非逻辑故障，了解并熟悉硬盘故障代码的相关意义，掌握一些常见的非逻辑故障的判断方法。然后，学习硬盘故障的排除方法。最后，达到稳固学生对硬盘的软硬件认识和强化学生动手能力的目标。

Design for the Hard Disk Troubleshooting Experiment in Data Recovery

Nowadays, the educations of the university pay more attention to the engineering and practical ability in addition to the theoretical education. In order to cooperate with the undergraduate course system and data recovering of the University of Electronic Science of Technology of China, this paper designs an experiment of how to do the hard disk troubleshooting. In the lab, students will first be grouped, get familiar with laboratory equipment, understand the classification of hard disk failure and fault causes, including logical failure and non-logical failure, at the same time, understand and be familiar with the relevance of fault codes, master some common method to judgment the non-logical failures, then learn the hard disk troubleshooting method. Finally, the goals are achieved that the student can have a good knowledge of the hard disk and their ability of operation is strengthened.
