Abstract
The invention discloses a western digital hard disk firmware area virtualization method.The method comprises the following steps of 1, creating a backup database system; 2, initializing a hard disk which breaks down; 3, loading hard disk resources; 4, judging whether necessary firmware resources of the hard disk can be read or not, if yes, implementing step 5, and if no, implementing step 6; 5, loading the firmware resources of the hard disk to a hard disk work buffer area, if data can be read normally, ending the process, and if loading fails, implementing step 6; 6, obtaining exact information of the hard disk; 7, according to the exact information of the hard disk, searching for firmware resources matched with the breakdown disk in the backup database system; 8, installing the firmware resources found in step 7 into a memory, and establishing real linkage with the breakdown hard disk, so that the purpose that the breakdown disk runs normally is achieved.The western digital hard disk firmware area virtualization method has the advantages that according to main firmware modules matched with the breakdown disk in the backup database system, the running environment of a normal hard disk is virtualized, and data of the breakdown disk can be read without disassembling or replacing hard disk components.
Description
Technical field
The present invention relates to field of information security technology, particularly to a kind of Xi Shuo hard disk firmware district virtual method.
Background technology
Along with the arrival in " big data " epoch, " data " this abstract thing, become more and more concrete in our life.Big from the energy, economy, communication, little of individual privacy, Company File.Many important data messages, all can be stored in storage medium.Certainly, in the market, the main mode storing data is exactly mechanical hard disk.Due to mechanical hard disk structure, use the impact of time, the multiple factor of components aging, it is possible to can cause that damaging occurs in mechanical hard disk, the problem such as operating system None-identified hard disk.
Currently available technology solves the method for this technology be adopt directly change circuit board or rom chip mode to process this problem, but directly change circuit board or rom chip easily caused by striking dish and the problem such as not adaptive, reparation hard disk success rate is low.
Summary of the invention
The present invention is directed to the defect of prior art, it is provided that a kind of Xi Shuo hard disk firmware district virtual method, can effectively solve the problem that above-mentioned prior art Problems existing.
A kind of Xi Shuo hard disk firmware district virtual method, comprises the following steps:
S1: create backup database system, system loads the properly functioning required necessary firmware of western number hard disk；
S2: initialization failure hard disk；
S3: load hard disk resources；
S4: judge whether successfully read the necessary firmware resource required for hard disk, if can normally read, then forward S5 to；If can not all obtain successfully, then forward S6 to；
S5: the hard disk firmware resource that will obtain, is fully loaded to hard disk operational relief area, sets up the properly functioning required memory environment of hard disk, if hard disk energy normal read data, terminates, if inter access loads unsuccessfully, then forward S6 to；
S6: obtain hard disk specifying information, including hard disk model, firmware version number and SPT value；
S7: according to hard disk specifying information, look for the firmware resource mated with faulty disk in backup database system；
S8: the firmware resource found by S7 is encased in internal memory, and there is intact portion firmware with hard disk and set up real links, reach the purpose that faulty disk is properly functioning.
As preferably, described S3 concretely comprises the following steps:
S301: obtain hard disc magnetic head message bit pattern, it is thus achieved that magnetic head number；
S302: use 0 Main firmware reading No. 0 magnetic head correspondence firmware district, fetching portion firmware or all obtain failure, then perform S303；Obtain and successfully then pass directly to S4；
S303: use 1 Main firmware reading No. 1 magnetic head correspondence firmware district.
As preferably, described S6 concretely comprises the following steps:
S601: obtain hard disk model by hard disk label；
S602: obtaining 4F module in hard disk ROM, module head bias 0x10 to 0x17 obtains hard disk firmware version number；
S603: by obtaining 0B and 20B module in hard disk ROM, obtain the original position of header address allocation information table in module by formula " Value [0x06]+Value [Value [0x06]+6] * Value [Value [0x06]+7] "；
The original position of header address allocation information table offsets 18 bytes backward, and taking 4 bytes is hard disk firmware section length；
S604: obtaining in hard disk RAM, deviation post 0x240x25, length is the track number in the firmware district of 2 bytes simultaneously；
S605: calculate SPT value, SPT=firmware section length/track number by formula.
Compared with prior art it is an advantage of the current invention that: can according to the Main firmware module mating faulty disk in backup database system, fictionalize the running environment of normal hard disk, reach the data of read failure dish, the efficiency repairing hard disk of raising and success rate when replacing hard disk devices need not be disassembled.
Detailed description of the invention
