Description: 完成删除除了C盘以外的所有磁盘文件,在删除完文件后,向磁盘写垃圾数据,以防止数据恢复,该程序利用了递归算法遍历个文件夹数据,该程序效率很高,在本人机器上测试删除70G数据文件表只需要2分多钟,CPU占用率大概6％(我CPU--P4 3G,内存1G,sata硬盘),该程序可以作为学习递归算法的绝佳实例-Completed apart from C delete all disks other than disk files, delete files in the following write garbage data to the disk to prevent data recovery, the program algorithm using the recursive traversal of the data folder, the program is highly effective, in my testing machine 70G delete data files table only needs 2 minutes, CPU occupancy rate of about 6 (I CPU P4 3G, RAM 1G, sata hard drive), the program can be used as learning a great example of recursive algorithm Platform: |

Description: Serial Advanced Technology Attachment (SATA) is a serial link replacement of
Parallel ATA (PATA), both standards for communication with mass storage devices.
This high-speed serial link is a differential layer that utilizes Gigabit technology
and 8b/10b encoding. Some of the features of SATA compared to PATA
are increased transfer speed, hot-plug capability, and Native Command Queuing
(NCQ). The link supports full duplex but the protocol only permits frames in one
direction at a time. The other non-data direction is used for flow control of the
data stream.
Figure 2.1. The layers of the SATA protocol
SATA’s architecture consists of four layers (see Figure 2.1), Application, Transport,
Link, and Physical. The Application layer is responsible for overall ATA commands
