Detailed description of the invention

Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit Determine the present invention.

The primary solutions of the embodiment of the present invention is: proposes a kind of hard disk analysis on the health status method, obtains Take the attribute information of hard disk, record the wear coefficient in described hard disk running；Believe according to described attribute Breath, described wear coefficient and the wear model being pre-configured with, obtain the wear extent of described hard disk；According to institute State attribute information, described wear coefficient and described wear extent, set up life model analysis and obtain described hard disk Health status.

The hard disk health and fitness information data parameters obtained due to prior art is few, and the health status for hard disk is divided Analysing the most unilateral, the detection data obtained make the health and fitness information obtaining hard disk that user cannot be directly perceived, understandable.

The present invention provides a solution, in conjunction with many information, and use habit based on user, The comprehensive health status analyzing hard disk, and it is presented to user by obtaining analysis result with the form being easily understood. The analysis result that the embodiment of the present invention obtains more conforms to the practical situations of each hard disk, has reliability And ease for use, solve that present hard discs health detection is unilateral, Monitoring Data can not intuitively reflect that hard disk is healthy The technical problem of situation.

With reference to Fig. 1, hard disk analysis on the health status method first embodiment of the present invention provides a kind of hard disk health shape Condition analyzes method, and described hard disk analysis on the health status method includes:

Step S10, the attribute information of acquisition hard disk, record the wear coefficient in described hard disk running.

It is owing to the health of hard disk is not only affected by attribute own, the most relevant with the service condition of user, Therefore, the data message in attribute information that the present invention configures according to hard disk and running, set up the life-span Model, analyzes the health status that hard disk is current comprehensively.Then current hard by simple user interface feedback The state of dish, allows users to health status directly perceived, to be apparent from hard disk, and then recommends user to adopt Take relevant optimization operation.

It should be noted that the hard disk in the present embodiment refers both to solid state hard disc (Solid State Drives, letter Claim SSD).

Concrete, as a kind of embodiment, the present embodiment obtains each of hard disk by hard disc detecting device Item data, carries out health analysis.It should be noted that detection device can be positioned at same calculating with hard disk In machine equipment, it is also possible to for single external detection device, can arrange the most flexibly.Detection Device, by the interface being pre-configured with, can read every data message of hard disk.

After card left by hard disk, the acquisition original ECC value of hard disk, ECC max-thresholds and maximum can be scanned The attribute informations such as abrasion number of times.

The attribute information of hard disk is the constant information of hard disk, and wherein, the original ECC value of hard disk is hard disk ECC state of dispatching from the factory, hard disk can be obtained in use as the ECC reference value of hard disk ECC value changes.Original ECC value is the resident information of hard disk, immobilizes.

ECC max-thresholds is when error in data being detected, the data bit number that maximum can be corrected.Work as inspection During the wrong data number the measured max-thresholds more than ECC, during beyond correction capability, read the number obtained According to correcting completely, unavailable.When the actual ECC value of the hard disc physical block max-thresholds more than ECC Time, then judge that this physical block is the worst, this physical block is replaced with spare block.

Greatest wear number of times is the erasable number of times of maximum of hard disk.In the running of hard disk, carry out logic Hard disk, it is avoided that hard disk does not carry out erasing operation, is caused abrasion by write operation.Actual mill when hard disk When damage number of times reaches greatest wear number of times, the end-of-life of hard disk.

After hard disk powers on, during carrying out daily reading and writing data, by WL (Wear Leveling, Abrasion equilibrium) keep the abrasion equilibrium of each physical block in SSD, use ECC (Error Correcting Code, Error checking and correction) correct the wrong data in data read process.

When bad block occurs in the physical block of hard disk, the address of bad block is mapped to standby good block, to realize Make to make good use of block when writing data and replace bad block.

The detection device records hard disk each item data in running, obtains wear coefficient.The mill obtained Damage parameter includes: present hard discs run total time, the total amount of data of write, current ECC value and current Abrasion number of times etc..

Wherein, after the operation total time of present hard discs is for opening card, the operation that powers on for the first time from hard disk starts timing, By the end of the current time of running, hard disk every time power on run temporal summation.Run and total time reflect use Family uses the time of hard disk.Current ECC value is the ECC value that hard disk runs to current time, can be root The average obtained according to the ECC value that each physical block of hard disk is current.

After the total amount of data of write is for opening card, from the beginning of hard disk powers on operation for the first time, run by the end of current Moment, hard disk every time power on run time write data total amount.The total amount of data of write reflects user's Data use habit.

After current abrasion number of times is for opening card, from the beginning of hard disk powers on operation for the first time, in time currently running Carve, the balance abrasion number of times of each physical block of hard disk (NandFlash Block).Owing to hard disk uses WL Carrying out abrasion equilibrium, the abrasion number of times therefore obtained can regard the average abrasion number of times of present hard discs as, also I.e. WLV (Wear Leveling Value, abrasion equilibrium value).

Thus, the every wear coefficient in hard disk running is obtained.Certainly, the wear coefficient of hard disk is also Can be other data, can arrange the most flexibly.

Step S20, according to described wear coefficient and the wear model that is pre-configured with, obtain the mill of described hard disk Damage amount.

After the attribute information obtaining hard disk and wear coefficient, according to the wear coefficient of hard disk be pre-configured with Wear model, obtain hard disk wear extent.

Concrete, as a kind of embodiment, detection device is provided with wear model, wear model in advance Include the ECC wear factor that hard disk wear coefficient is corresponding.During ECC value is for reading data, entangle Positive wrong data bit (bit) number.Along with the increase of hard disk abrasion number of times, the error number of hard disc data Also can be gradually increased, ECC wear factor characterizes the hard disk ECC value variation characteristic with abrasion number of times.

ECC wear factor can obtain by hard disk is carried out wear test analysis.Due to solid state hard disc bag Include multiple type, such as SLC (Single-Level Cell, single-layer type stores), MLC (Multi-Leveled Cell, multiple field stores) and TLC (Triple-cellCell, three-layer type stores), and, different factories Family, the production technology for same type hard disk there is also difference, therefore, to present hard discs same type, Carrying out wear test with a batch of hard disk, analyzing the ECC wear factor that obtains can table the most accurately Levy the ECC value of present hard discs and the relation of abrasion number of times.ECC wear factor is different abrasion number of times pair The ECC value variation coefficient answered, the ECC value characterizing unit abrasion corresponding to different abrasion number of times interval increases Amount speed.

According to the number of times that currently weares and teares of hard disk, wear model acquisition current abrasion number of times can be searched corresponding ECC wear factor.

The ECC value that total run time according to hard disk and hard disk increase at present, obtains hard disk at default list The ECC value increased in bit time, namely the Average increases of ECC.Such as, the default unit interval is taken It is one day, then obtains the ECC value of hard disk increase average every day, namely ECC Per Day.

Thus, the wear extent of hard disk is obtained.The wear extent of hard disk can be that hard disk is in the default unit interval The ECC value of interior increase, namely the Average increases of ECC；The wear extent of hard disk can also is that current abrasion The ECC wear factor that number of times is corresponding.

Step S30, according to described attribute information, described wear coefficient and described wear extent, set up life-span mould Type analysis obtains the health status of described hard disk.

After obtaining the wear extent of hard disk, according to attribute information, wear coefficient and the wear extent of hard disk, build The life model of vertical hard disk, analyzes the health status obtaining hard disk.

As a kind of embodiment, first, the ECC increased at present according to total run time and the hard disk of hard disk Value, obtains the ECC value that hard disk increased within the default unit interval, namely the Average increases of ECC. Such as, taking the default unit interval is one day, then obtain the ECC value that hard disk increases average every day, namely ECC Per Day。

Taking the default unit interval is t, and in hard disk unit interval t, the data volume of write is Data₁, hard disk list The ECC value increased in bit time t is ECC₁, then ECC1 is the data volume of hard disk write is Data₁ Time, the corresponding ECC value increased.Owing in hard disk unit interval t, the data volume of write characterizes user's Data use state, namely the use habit of user, then, the ECC value table increased in unit interval t Levy the ECC loss that hard disk run unit time t is caused.

After obtaining hard disk wear extent within the default unit interval, according to the ECC max-thresholds of hard disk, Obtain the time that hard disk reaches the maximum error correction threshold value of ECC from current ECC value, and using this time as firmly The residual life of dish.

Then, continue to run with current user's use habit with hard disk, the number of write of each unit interval According to amount keep constant on the basis of, be calculated the operation time when often increasing a unit interval, hard disk surplus The remaining life-span.

Then, according to operation time and the residual life of hard disk, set up the life model of hard disk, with reference to figure 10, can be Y-axis using the operation time of hard disk as X-axis, the residual life of hard disk, obtain hard disk Life model.

Then, according to the life model of hard disk, according to the health status of default standard analysis hard disk.

Such as, if the Average increases of the ECC of present hard discs is less, and residual life is longer, then judge Being in a good state of health of present hard discs；If the Average increases of the ECC of present hard discs is relatively big, and the residue longevity Order longer, then judge that the health status of present hard discs is general；If the Average increases of the ECC of present hard discs Relatively big, and residual life is shorter, then judge that the health status of present hard discs is poor.

Thus, the analysis result to hard disk health status is obtained.

As another embodiment, ECC wear factor is the interval interior different abrasion number of times of unit abrasion Corresponding ECC value variation coefficient, namely the ECC value variation coefficient that the different abrasion number of times of hard disk are corresponding.

After obtaining the ECC wear factor that hard disk is current, can be according to the current ECC value of hard disk, ECC Max-thresholds and ECC wear factor, obtain the residue abrasion number of times that hard disk is current.

Then according to current residue abrasion number of times and the number of times that currently weares and teares of hard disk of hard disk, run total time Between, obtain the residual life of hard disk, set up life model, analyze the health status of hard disk.

Then, the analysis on the health status result obtained is fed back to user with the form of user interface, notice The health status of user's present hard discs, and provide corresponding Optimizing Suggestions according to the use habit that user is current, It is easily understood.Such as: the suggestion timely Backup Data of user, capacity etc. is reduced.

It should be noted that analysis on the health status result can feed back to user with the form of life model, The form such as word, figure can also be made, can arrange the most flexibly.

In the present embodiment, by obtaining the attribute information of hard disk, the abrasion in recording disk running Parameter, then according to wear coefficient and the wear model being pre-configured with, obtains the wear extent of hard disk；Then, Attribute information, wear coefficient and wear extent according to hard disk, sets up life model analysis and obtains the strong of hard disk Health situation.The present embodiment is pre-configured with wear model, and according to hard disk abrasion ginseng in running Number, can obtain use habit and the hard disk wear extent of user, thus according to wear extent and hard disk itself Attribute information and user habit, set up life model, and comprehensive analysis obtains the health status of hard disk.This reality Execute example and achieve many information that combines, use habit based on user, the comprehensive health analyzing hard disk Situation, and it is presented to user by obtaining analysis result with the form being easily understood.The embodiment of the present invention obtains Analysis result more conform to the practical situations of each hard disk, there is reliability and ease for use, solve Present hard discs health detection is unilateral, Monitoring Data can not intuitively reflect the technical problem of hard disk health status.

Further, with reference to Fig. 2, hard disk analysis on the health status method the second embodiment of the present invention provides one Hard disk analysis on the health status method, based on the embodiment shown in above-mentioned Fig. 1, described wear coefficient includes institute State the operation total time of hard disk, write total amount of data, current ECC value and the number of times that currently weares and teares, described firmly The attribute information of dish includes the ECC max-thresholds of described hard disk, and described step S20 includes:

In the running of hard disk, what the wear coefficient of acquisition included hard disk runs total time, write Total amount of data, current ECC value and the number of times that currently weares and teares.

After obtaining abrasion number of times, according to abrasion number of times and the wear model being pre-configured with, obtain hard disk Current ECC wear factor.

Concrete, as a kind of embodiment, the wear model being pre-configured with can be the ECC value of hard disk With abrasion number of times variation coefficient model, have recorded hard disk respectively wear and tear corresponding to number of times ECC value change system Number.Then according to the number of times that currently weares and teares of hard disk, searching wear model, obtaining corresponding ECC value change is Number, using the ECC value variation coefficient that obtains as the current ECC wear factor of hard disk.

As another embodiment, the wear model being pre-configured with is that the ECC value of hard disk is with abrasion number of times Variation coefficient model, have recorded hard disk abrasion ECC value variation coefficient corresponding to time intervals value.Then According to the number of times that currently weares and teares of hard disk, the abrasion time intervals value belonging to lookup, obtain interval value corresponding ECC value variation coefficient, using the ECC value variation coefficient that obtains as the current ECC wear factor of hard disk.

It should be noted that in the present embodiment, ECC value variation coefficient, namely ECC wear factor is In unit abrasion is interval, ECC value is with the incremental velocity of abrasion number of times, and different abrasion number of times correspondences is different ECC value variation coefficient.Such as, when current abrasion number of times is 1000 times, abrasion number of times often increases by 200 Secondary, ECC value increases by 5, then the ECC value variation coefficient of abrasion number of times 1000 correspondence is 5/200 time；When When front abrasion number of times is 2000 times, abrasion number of times often increases by 200 times, and ECC value increases by 7, then abrasion time The ECC value variation coefficient of several 2000 correspondences is 7/200 time.

Thus, obtain the current ECC wear factor of hard disk, using the ECC wear factor that obtains as firmly The wear extent of dish.

Then, continue to run with current user's use habit with hard disk, the number of write of each unit interval Keep constant according to amount, run abrasion number of times and the residue abrasion number of times of hard disk of time according to hard disk, obtain The residual life of hard disk.

It should be noted that in the present embodiment, the ECC max-thresholds of hard disk can be that hard disk is actual ECC max-thresholds, it is also possible to be the warning value of hard disk actual ECC max-thresholds, such as ECC is maximum The 90% of threshold value, 80% etc., can arrange the most flexibly.

After obtaining the life model of hard disk, operational factor based on hard disk, according to default standard analysis Obtain the health status of hard disk.

Continue to run with current operational factor with hard disk, namely hard disk keeps current unit interval write On the basis of data volume is constant, analyze the health status of hard disk.

Such as, if present hard discs unit interval write data volume is less, and residual life is longer, then judge Being in a good state of health of present hard discs；If present hard discs unit interval write data volume is relatively big, residual life Longer, then judge that the health status of present hard discs is general；If present hard discs unit interval write data volume is relatively Greatly, residual life shorter, then judge that the health status of present hard discs is poor.

Thus, the analysis result to hard disk health status is obtained.

In the present embodiment, wear coefficient includes running total time, write total amount of data, current ECC value Currently wear and tear number of times, and the attribute information of hard disk includes the ECC max-thresholds of described hard disk, according to hard disk Current abrasion number of times and wear model, the ECC wear factor obtaining hard disk current is wear extent；Then, According to running total time and write total amount of data, currently wearing and tearing number of times, obtain the operational factor of hard disk；So After, according to current ECC value, ECC max-thresholds and the current ECC wear factor of hard disk, obtain hard The residue abrasion number of times of dish；Then, based on operational factor, according to the residue abrasion number of times of hard disk, set up Life model, analyzes the health status obtaining described hard disk.The present embodiment obtains by setting up life model The residual life of hard disk, and according to operation total time of hard disk and total amount of data, obtain the use of user Custom, thus use habit based on user, the attribute information of hard disk itself and life model analyze hard disk Health status, it is achieved that the comprehensive analysis to hard disk health status, result more accurately, directly perceived.
