| 摘 要： | 针对在windows操作系统下对磁性存储介质进行数据销毁时容易感染病毒的难题，提出基于ARM架构的Linux系统作为开发平台，采用Qt／Embedded作为开发工具，利用其信号与槽机制，然后通过建立交叉编译环境，在ARM机上对磁性存储介质磁盘扇区数据直接数据覆盖，最终可实现对Qt／Embedded数据销毁程序向ARM机的移植。实验表明在基于ARM平台的Linux系统下进行磁盘扇区的直接数据覆盖是有效的。

| Abstract: | Data destruction of magnetic storage media based on Linux and Qt/Embedded has been a difficult problem. The Linux OS based on ARM is used as developing platform and Qt/Embedded is used as developing tools. The signals and slots of Qt/Embedded are especially applied in this system. Then data coverage on disk sector of magnetic storage media on ARM can be realized by constructing cross -compiling environment and transplantation. The testing results show that direct data coverage on disk sector in Linux based on ARM is effective. |
