Description
Technical Field
The invention belongs to the field of system access and the field of data recovery, and relates to a method for mounting a hard disk by adopting a PCIE card.
Background
In the process of data recovery, if a failed hard disk is accessed to a computer of a Windows operating system, the Windows operating system is easily blocked. However, if the switching device card (for example, PCIE card) and the device card control driver are used 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, the hard disk cannot be viewed and operated in the Windows operating system. If we need to check and operate the fault hard disk inserted in the switching equipment card on the Windows operating system, the hard disk needs to be mounted on the Windows operating system, so that various operations can be directly carried out on the hard disk in the system.
Disclosure of Invention
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 failed hard disk are filled into a structural body of a Windows operating system, a notice of equipment change is sent to a virtual micro port driver, the Windows operating system mounts the failed hard disk to the Windows operating system according to the filled structural body, and the virtualization technology of the Windows operating system is utilized to mount the failed hard disk to the Windows operating system, so that the failed hard disk is normally identified in the Windows operating system. 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: sending an instruction to the virtual miniport driver, filling the parameters into a structural body of a Windows operating system, and sending a notification of equipment change to the virtual miniport driver after filling;
s300: and after the virtual micro-port driver receives the notification of the equipment change, the virtual micro-port 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: sending an instruction for acquiring parameters of the hard disk to acquire the parameters of the hard disk, wherein the parameters comprise hard disk capacity, module information and a hard disk serial number;
s102: and sending the acquired parameters of the hard disk as a mounting request to the virtual miniport driver.
Preferably, the step S200 includes the steps of:
s201: the virtual micro port driver receives a mounting request, searches an unused memory space for storing parameters of a hard disk to be mounted, wherein the size of the memory space is not less than the size of a structure body INQUIRYDATA of a Windows operating system;
s202: writing an InQUIRYDATA structure into the memory space: the InQUIRYDATA structural body is used for describing the parameters of the hard disk, and the members required to be written into the InQUIRYDATA structural body and the corresponding meanings are shown in a table 1;
table 1: members to be written into an InQUIRYDATA structure and corresponding meanings
S203: sending a notification of a device change.
Preferably, the step S300 includes the steps of:
s301: the virtual miniport drives a trigger response function and queries a response function SCSIOP _ 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 invention has the beneficial effects that: the method solves the technical problem that in the prior art, after the PCIE card is adopted to mount the fault hard disk, the fault hard disk cannot be checked and operated under a Windows operating system.
