Description
Technical Field
The invention belongs to the field of system access and data recovery, and relates to a method for mounting a hard disk by using a PCIE card.
Background
In the process of data recovery, if a fault hard disk is accessed to a computer of a Windows operating system, the Windows operating system is easy to be blocked. But if we use the transit device card (e.g., PCIE card) and the device card control driver to access the failed hard disk, the failed hard disk can be accessed without affecting the normal operation of the Windows operating system. However, the problems in the prior art are: although we can operate a failed hard disk by controlling the drive, it is not possible to view and operate the hard disk in the Windows operating system. If the fault hard disk inserted in the adapter device card is required to be checked and operated on the Windows operating system, the hard disk is required to be mounted on the Windows operating system, so that various operations can be directly carried out on the hard disk in the system.

Aiming at the defects of the prior art, the invention provides a method for mounting a hard disk by adopting a PCIE card, which is characterized in that parameters of a fault hard disk are filled into a structural body of a Windows operating system, a notification of equipment change is sent to a virtual miniport driver, the Windows operating system mounts the fault hard disk to the Windows operating system according to the filled structural body, and the fault hard disk is mounted on the Windows operating system by utilizing the virtualization technology of the Windows operating system, so that the normal identification of the fault hard disk in the Windows operating system is realized. The application of the invention comprises the following steps:
s100: connecting the hard disk to a computer of a Windows operating system through a PCIE card, acquiring parameters of the hard disk and sending the parameters to a virtual micro port driver;
s200: transmitting an instruction to the virtual micro port driver, filling the parameters into a structural body of a Windows operating system, and transmitting a notification of equipment change to the virtual micro port driver after filling;
s300: after the virtual miniport driver receives the notification of equipment change, the virtual miniport driver sends the received data to a Windows operating system, and the Windows operating system mounts the hard disk to the Windows operating system according to the filled structure.
Preferably, the step S100 includes the steps of:
s101: transmitting an instruction for acquiring parameters of a hard disk to acquire the parameters of the hard disk, wherein the parameters comprise the capacity of the hard disk, module information and serial numbers of the hard disk;
s102: and sending the acquired parameters of the hard disk to the virtual micro port driver as a mounting request.
Preferably, the step S200 includes the steps of:
s201: the virtual miniport driver receives the mounting request, searches an unused memory space and is used for storing parameters of a hard disk to be mounted, wherein the size of the memory space is not smaller than that of a structure INQUIRYDATA of a Windows operating system;
s202: writing INQUIRYDATA structure into the memory space: the INQUIRYDATA structure is used for describing the hard disk parameters, and members required to be written into the INQUIRYDATA structure and corresponding meanings are shown in table 1;
table 1: members of the structure to be written in INQUIRYDATA and their corresponding meanings
S203: a notification of the device change is sent.
Preferably, the step S300 includes the steps of:
s301: the virtual miniport driver triggers a response function and queries a response function SCSOP_INQUIRY;
s302: and sending the written structure INQUIRYDATA to a Windows operating system, and identifying and analyzing the hard disk parameters and mounting the hard disk by the Windows operating system.
The beneficial effects of the invention are as follows: the technical problem that in the prior art, after a fault hard disk is mounted by adopting a PCIE card, the fault hard disk cannot be checked and operated under a Windows operating system is solved.
