Method for realizing isolation of defective hard disk based on PCI-E device

Abstract

The invention discloses a method for realizing isolation of a defective hard disk based on a PCI-E device, and the method is characterized by comprising the following steps: S100, connecting the defective hard disk to the PCI-E device, and connecting the PCI-E device to a PCI-E channel of a computer mainboard, wherein the PCI-E device has a function of switching the SATA interface and comprises aswitching chip for switching PCI-E into SATA, the PCI-E interface and the SATA interface; S200, enabling the upper computer to encrypt the original instruction and send the encrypted pseudo instruction and data to a drive program of the PCI-E device; S300, enabling the drive program of the PCI-E device to receive and decrypt the pseudo instruction sent by the upper computer, and sending the decrypted instruction to the defect hard disk of the specified port; S400, enabling the drive program of the PCI-E device to wait for the response of the defective hard disk, and returning a result to the upper computer.

Description

technical field [0001] The invention belongs to the field of data recovery, and relates to a method for isolating a defective hard disk, in particular to a method for isolating a defective hard disk based on a PCI-E device. Background technique [0002] In the field of data recovery, with the continuous expansion of hard disk capacity and the increasing user base of hard disks, more and more cases of hard disk damage have occurred. When the computer is directly connected to the hard disk, the computer will directly use the read ATA command to access Hard disk, if the defective hard disk is directly connected to the computer, both the computer and the hard disk may be stuck. [0003] When it is necessary to extract hard disk data, or other situations that require access to the hard disk, the hard disk is generally used to directly connect to the computer operating system, and the data on the hard disk is accessed using the read command. In particular, a defective hard drive ...

[0003] When it is necessary to extract hard disk data, or other situations that require access to the hard disk, the hard disk is generally used to directly connect to the computer operating system, and the data on the hard disk is accessed using the read command. In particular, a defective hard drive may cause the computer and / or the hard drive to freeze
