Description
Technical field
The present invention relates to field of information security technology, in particular to a kind of Xi Shuo hard disk firmware area virtual method.
Background technique
With the arrival in " big data " epoch, " data " this abstract thing becomes increasingly in our life
Specifically.It is small to arrive individual privacy, Company File greatly from the energy, economy, communication.Many important data informations can be all stored in
In storage media.Certainly, currently on the market, the main mode of storing data is exactly mechanical hard disk.Due to the construction of mechanical hard disk,
Using time, the influence of components aging Multiple factors, it may result in mechanical hard disk and damage, operating system can not identify firmly
The problems such as disk.
The method that this technology is solved in currently available technology is by the way of directly replacement circuit board or rom chip
This problem is handled, but directly changes circuit board or rom chip easily causes the problems such as striking disk and not being adapted to, repairs hard disk
Success rate is low.
Summary of the invention
The present invention in view of the drawbacks of the prior art, provides a kind of Xi Shuo hard disk firmware area virtual method, can effectively solve
Certainly the above-mentioned problems of the prior art.
A kind of Xi Shuo hard disk firmware area virtual method, comprising the following steps:
S1: creation backup database system, system are packed into necessary firmware needed for western number hard disk operates normally；
S2: initialization failure hard disk；
S3: load hard disk resources；
S4: necessity firmware resource required for hard disk can successfully be read by judging whether goes to if can normally read
S5；If success cannot be obtained all, S6 is gone to；
S5: the hard disk firmware resource that will acquire is fully loaded to hard disk operational buffer area, establishes needed for hard disk normal operation
Memory environment, terminate if hard disk energy normal read data, if inter access load failure, go to S6；
S6: hard disk specifying information, including hard disk model, firmware version number and SPT value, S6 specific steps are obtained are as follows:
S601: hard disk model is obtained by hard disk label；
S602: obtaining 4F module in hard disk ROM, and module head bias 0x10 to 0x17 obtains hard disk firmware version number；
S603: by obtaining 0B and 20B module in hard disk ROM, pass through formula " Value [0x06]+Value [Value
[0x06]+6] * Value [Value [0x06]+7] " obtain the initial position of header address allocation information table in module；
The initial position of header address allocation information table deviates 18 bytes backward, and taking 4 bytes is the hard disk firmware head of district
Degree；
S604: while obtaining in hard disk RAM, deviation post 0x24 0x25, length is the track number in the firmware area of 2 bytes；
S605: SPT value, SPT=firmware section length/track number are calculated by formula；
S7: it according to hard disk specifying information, is looked in backup database system and the matched firmware resource of faulty disk；
S8: the firmware resource that S7 is found is encased in memory, and is had existed intact portion firmware with hard disk and established
Real links achieve the purpose that faulty disk operates normally.
Preferably, the S3 specific steps are as follows:
S301: obtaining hard disc magnetic head message bit pattern, obtains magnetic head number；
S302: the Main firmware that No. 0 magnetic head corresponds to firmware area, fetching portion firmware or all acquisition are read using 0
Failure, then execute S303；It obtains and successfully then passes directly to S4；
S303: the Main firmware that No. 1 magnetic head corresponds to firmware area is read using 1.
Compared with prior art the present invention has the advantages that can according in backup database system match faulty disk it is main
Firmware module fictionalizes the running environment of normal hard disk, reaches and does not read event in the case where needing dismantling replacement hard disk devices
Hinder the data of disk, the efficiency and success rate of the reparation hard disk of raising.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, by the following examples, to the present invention do into
One step is described in detail.
A kind of Xi Shuo hard disk firmware area virtual method, comprising the following steps:
