站搜网 Win10 频道9月22日消息 通常来说如果有一些机密数据需要销毁的话最好的办法便是采用物理破坏的方式,除此以外才会考虑格式化。而如何在不破坏硬件的前提下安全清除那些自己想清除的数据呢?

近日腾讯玄武实验室负责人,人称TK教主的于旸便通过微博科普了如何使用Format命令安全删除整个分区的方法。据悉,使用这种方法删除的数据不可能被恢复,安全性佳。

于旸表示,目前Windows的Format命令已经支持安全擦除整个分区。Format命令加上/P参数后,就会把每个扇区先清零,再用随机数覆盖。而且可以覆盖多次。比如“format D: /P:8”就表示把D盘用随机数覆盖8次。

那如何用Windows自带功能在不格式化磁盘的情况下安全删除文件呢?Cipher命令本来是用于磁盘加密的,但有个/W参数可对磁盘上未使用的空间进行覆盖。比如你刚刚删除了D:\Private目录下的几个文件,那么执行一下“cipher /w:D:\Private”。D盘上未使用空间就会被覆盖三次:一次0x00、一次0xFF,一次随机数。所有被删除的文件就都不可能被恢复了。
