Embodiment Construction

[0047] The present invention takes the solid-state hard disk controlled by SM2258G (that is, the main control chip of the solid-state hard disk is SM2258G series) as an example, and proposes a method for realizing the physical data extraction of the solid-state hard disk. figure 1 A general flowchart of the method provided by the present invention is shown. Such as figure 1 shown, including the following steps:

[0048] S100: Determine whether the solid state disk is ready normally, if yes, perform step S200, otherwise end the process;

[0049] Step S100 includes the following steps:

[0050] S101: Connect the solid-state hard drive to the computer using the SATA interface;

[0051] S102: Determine whether the solid state disk is ready, if yes, perform step S200, otherwise end the process.

[0052] S200: Obtain the extraction authority of the physical data of the solid-state hard disk;

[0053] S201: Obtain the attributes of the solid state drive, including whether it is ...

Abstract

The invention discloses a method for extracting physical data of a solid state disk, and the method is characterized in that the method the following steps: S100, judging whether the solid state diskis normally ready or not, if so, executing step S200, and otherwise, ending a process; S200, obtaining an extraction permission of the physical data of the solid state disk; S300, analyzing the basicparameters of the solid state disk; S400, circularly extracting the physical data of the solid state disk, comprising the following steps: S401, acquiring the minimum unit of the extracted physical data; S402, acquiring data of a physical page of the solid state disk; S403, extracting physical data of the solid state disk.

Description

technical field [0001] The invention belongs to the field of information security technology and data restoration, and relates to a method for extracting physical data of a solid-state hard disk. Background technique [0002] In the field of information security technology and data recovery, the capacity of hard disks continues to increase and the usage of hard disks continues to expand. At the same time, the shipments of hard disk drives (HDDs) continue to decline, and the shipments of solid-state drives (SSDs) continue to increase. Since 2010, solid-state drive SSD shipments have begun to grow rapidly, and have maintained a growth rate of more than 10% for nine consecutive years: the growth rate in 2015 was 30.4%, and the growth rate of solid-state drive SSD shipments in 2018 was 37.2%; It is estimated that in 2020, the shipment of solid-state drives (SSDs) will increase to more than 200 million pieces. [0003] Solid state drives (SSDs) are widely used because of their f...
