在研究Windows操作系统中文件管理系统NTFS的基础上,提出一种彻底清除磁盘数据的方法。NTFS对文件的访问操作,主要通过与文件相关的MFT表进行,这与FAT系统存在较大差异。通过分析MFT表管理磁盘数据的方法,建立一种树形目录结构,并以该树形目录作为管理磁盘中所有MFT表的工具。采用遍历之后立即释放树结点的方法,解决了内存过度占用的问题。该技术可以在磁盘扇区直接清除数据,还可对数据进行更加直接的管理,减少了对操作系统的依赖,可操作性和安全性良好。

Based on the study of the document management system NTFS in Windows,this paper proposes a technology for clearing disk data completely.In NTFS the access operation to the files is completed by MFT that is related to the files,so there is a big difference from the FAT system.A tree directory structure is constructed by analyzing the method of MFT managing disk data.The tree directory structure is used as the tool of managing all the MFT tables in the disk.The problem of excessive memory occupation is solved by using the technique of releasing the tree nodes immediately after they are traversed.The technology can not only clear the data directly in the disk sector,but also manage the data more directly.Moreover,it reduces the dependence on the operation system,and it also has the advantages of operability and safety.
