Remote Access Technology of Hard Disk Based on Embedded System

In this paper, we propose a hard disk remote access method based on the embedded system. The proposed method can achieve hard disk remote access when the computer is turned off. A SATA switch module is designed to control the high-speed data channel of the hard disk. A communication design of the Linux system is used to realize the data interaction between the embedded system and the hard disk. The experiment verifies that the proposed method can remotely access the hard disk when the computer is turned off. Compared with the remote desktop technology, the proposed method improves system compatibility and transmission efficiency. Compared with the NAS storage, the proposed method reduces power consumption. Compared with the cloud storage, the proposed method protects data privacy and improves storage space utilization.
