Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.In the absence of conflict, this Shen
Please in embodiment and embodiment in feature can be combined with each other.
The embodiment of the present invention is applicable in the scene for determining that hard disk does not power on duration, for example, determining when not powering on of mechanical hard disk
Long scene.Fig. 1 does not power on the schematic diagram of the method application scenarios of duration for determining hard disk a kind of in the embodiment of the present invention, such as schemes
Shown in 1, controller is connect with hard disk, can recorde operating parameter when hard disk is in different working condition, and power in hard disk
When, operating parameter when being in different working condition according to hard disk calculates hard disk and does not power on duration, and output prompt information.
In the embodiment of the present invention, controller can be the controller of hard disk, or when hard disk powers on, the host etc. that is connect with hard disk
The controller of equipment can also be the controller (as shown in Figure 1) being independently arranged, or can also be the group of above controller
It closes.
Fig. 2 is the schematic flow chart for the method that the determination hard disk provided according to one embodiment of the invention does not power on duration.
One embodiment of the invention provides a kind of method that determining hard disk does not power on duration, can be executed by controller,
As shown in Fig. 2, this approach includes the following steps.
101, controller determines the working condition of hard disk according to the supply voltage of hard disk.
Wherein, the working condition of hard disk includes power-up state and power-down state.Power-up state refers to that hard disk and host etc. are outer
The connection of portion's equipment, the equipment such as host are the state of its power supply, and hard disk can usually carry out data read-write operation at this time.Power-down state is
Refer to the state that hard disk does not have external equipment for its power supply, hard disk cannot usually carry out data read-write operation at this time.For machinery
For hard disk, when there is external equipment to power for it, supply voltage can achieve operating voltage, such as 5 volts, in mechanical hard disk
Disk etc. can just run, i.e., mechanical hard disk is in power-up state；And when no external equipment is powered for it, supply voltage
Operating voltage cannot be reached, usually 0 volt, disk in mechanical hard disk etc. cannot be run, i.e., mechanical hard disk is in power-down state.
So working condition locating for hard disk and hard disk operational can be determined in the embodiment of the present invention by the supply voltage of hard disk
The information such as at the time of state changes.
102, when the working condition of hard disk enters power-down state by power-up state, controller is joined according to the operation of hard disk
Number, effective lower electric moment of recording disk.
Wherein, the effectively lower electric moment indicates that hard disk reaches preset duration in the lasting duration of power-up state (powering on duration)
The lower electric moment of lower electricity afterwards, i.e. hard disk be in when power-up state meets or exceeds preset duration the lower electricity moment of lower electricity again.Hard disk
Operating parameter may include hard disk be in power-up state power on duration.In the embodiment of the present invention, controller is determining hard disk
Working condition after, that is, can determine that the operating parameter of hard disk, and then can recorde effective lower electric moment of hard disk.
It should be noted that only it continues certain time length (for example, 2 is small in power-up state for mechanical hard disk
When) in the case where, air filtration structure could effectively filter the volatile materials to volatilize in mechanical hard disk, and only have
The volatile materials that effect filters out mechanical hard disk could reduce the probability that mechanical hard disk breaks down.If mechanical hard disk is powering on
After fail to reach certain time length just lower electricity, then mechanical hard disk this time powers on effective there is no carrying out to volatile materials therein
Filtering, although mechanical hard disk is excessively electric at this time, is not still avoided that due to volatile materials is sticked to magnetic head or disk
The case where causing hard disk to break down, thus in such cases the power up of mechanical hard disk be it is invalid, then in such cases
The lower electric moment be also invalid.
It should be noted that controller will record when each hard disk operational state enters power-down state by power-up state
The effectively lower electric moment is remembered when so effective lower electric moment of controller record being electricity under hard disk last time in the embodiment of the present invention
Effective lower electric moment of record.
103, when the working condition of hard disk is again introduced into the power-up state by the power-down state, controller record is hard
Disk powers on the moment.
Wherein, controller can power on the moment by recording disk when hard disk is again introduced into power-up state by power-down state,
In order to not power on duration by powering on constantly for hard disk come calculate hard disk.Wherein, the record includes not having in controller
The hard disk records this and powers on the moment or have been recorded with when powering on the moment of the hard disk in the controller when powering on the moment, more
New record powers on the moment.
It should be noted that in one embodiment of the present invention, in step 102 and step 103 the effectively lower electric moment and
Power on the moment is detected to obtain by controller；In another embodiment of the present invention, effectively lower electricity in step 102 and step 103
Moment and power on the moment can by controller by read timing circuit generation time obtain.
104, controller according to effectively lower electric moment and powering on calculate hard disk constantly do not power on duration.
Wherein, controller defines powering on for hard disk when hard disk operational state enters power-up state by power-down state
Moment, in conjunction with the effectively lower electric moment of hard disk can calculate hard disk do not power on duration.It is described a length of described when not powering on
The difference at the effective lower electric moment for powering on moment and the hard disk of hard disk.
105, when hard disk is not when powering on duration more than or equal to the first preset duration, controller exports prompt information.
Wherein, what prompt information was used to prompt user's hard disk do not power on duration, i.e. prompt user's hard disk does not power on duration
The first preset duration is reached, the probability to break down is higher, and user is needed to handle in time.First preset duration can root
It determines, such as is set as 6 months according to the specific performance of hard disk.
It should be noted that step 103 to step 105 is hard disk operational state by power-down state in the embodiment of the present invention
The data handling procedure executed when into power-up state, for controller when hard disk powers on, calculate hard disk immediately does not power on duration,
If the duration that do not power on of hard disk reaches the first preset time, user can be prompted at the first time, avoids hard disk in subsequent use
It breaks down in the process.Step 101 with step 103 to step 105 there is no stringent chronological order, i.e., on hard disk
When electric, need to be implemented step 103 to step 105, and it is electric under hard disk when, need to be implemented step 102, in order to be able to guarantee hard
The accuracy at disk effectively lower electric moment, and then guarantee that the hard disk being calculated does not power on the accuracy of duration.
In the embodiment of the present invention, controller can determine the power-up state and power-down state of hard disk by supply voltage,
And when hard disk operational state enters power-down state by power-up state, operating parameter based on the hard disk determines its effectively lower electricity
Moment；When hard disk is again introduced into power-up state by power-down state, based on the effectively lower electric moment and moment computer can be powered on
Tool hard disk does not power on duration；If hard disk does not power on duration more than or equal to the first preset duration, prompt information is exported, with
Prompt user's hard disk does not power on duration.Mechanical hard disk can so be powered in user in use, if when using long
Between the mechanical hard disk that does not power on, can recognize the case where mechanical hard disk does not power on for a long time by prompt information, and then can be with
Mechanical hard disk is handled in time, is avoided because having used the mechanical hard disk not powered on for a long time, and makes to be stored in mechanical hard disk
In loss of data, cause unnecessary loss.
In a kind of optional embodiment of the embodiment of the present invention when supply voltage is greater than or equal to predeterminated voltage, determine
Hard disk is in power-up state；When supply voltage is less than predeterminated voltage, determine that hard disk is in power-down state.
Wherein, in the embodiment of the present invention, predeterminated voltage indicates required voltage when hard disk works normally, so working as power supply
When voltage is greater than or equal to predeterminated voltage, voltage needed for expression power supply has reached hard disk operational, hard disk be can work normally,
Determine that hard disk is in power-up state；When supply voltage is less than predeterminated voltage, electricity needed for expression power supply is not up to hard disk operational
Pressure, hard disk can not work, and determine that hard disk is in power-down state.
It should be noted that the value of predeterminated voltage can be configured according to concrete scene, usually more than hard disk is normal
The value of supply voltage when work.The variation of supply voltage value embodies the variation of hard disk operational state, while hard disk is in power supply electricity
Pressure could work normally when reaching the voltage value needed for working normally, so the change situation of supply voltage also embodies hard disk work
Make the situation of change of state.When electric under hard disk, supply voltage can drop to zero from normal operating voltage value.It is default in setting
When the value of voltage, if the controller in the embodiment of the present invention includes hard disk controller, that is, pass through hard disk controller recording disk
Effective lower electric moment, then need to guarantee that hard disk controller after determining that hard disk enters power-down state, can have sufficient time to
Effective lower electric moment of recording disk, therefore to avoid predeterminated voltage setting too small, cause hard disk controller to determine that hard disk enters
After power-down state, have little time effective lower electric moment of recording disk, so cause record the effectively lower electric moment and calculating it is hard
Disk powers on duration and mistake occurs.
In the optional embodiment of another of the embodiment of the present invention, the operating parameter of hard disk include hard disk be in power on shape
State powers on duration；So when hard disk enters power-down state by power-up state, according to the operating parameter of hard disk in step 101,
The step of effective lower electric moment of recording disk, can specifically execute are as follows: what recording disk be in power-up state powers on duration and firmly
Disk enter power-down state when the front lower electric moment；When length is greater than the second preset duration upon power-up, it will update at the effectively lower electric moment
For when the front lower electric moment；It is failed to grow up when the second preset duration upon power-up, is kept for the effectively lower electric moment constant.
Wherein, due to for mechanical hard disk, only it is after normally powering on and reaching certain time length, i.e., hard disk is in upper
Electricity condition powers on duration greater than the second preset duration, could carry out effective mistake to the volatile materials to volatilize in mechanical hard disk
Filter, so be in powering on duration and determining and whether effectively to power on for power-up state based on hard disk in the embodiment of the present invention, and then true
Whether what is recorded surely is effective when the front lower electric moment.If it is determined that when the front lower electric moment is effective, then by effective lower electric moment of hard disk
It is updated to when the front lower electric moment；If it is determined that will then keep the effectively lower electric moment constant when the front lower electric moment is invalid.Power on duration
It can be determined, such as be set as two hours according to the specific performance of hard disk.
In the embodiment of the present invention, power on duration by what hard disk was in power-up state, come judge this hard disk power on whether
Effectively, so determine hard disk this lower electric moment whether be it is effective, in order to the effective lower electricity moment for the hard disk that timely updates,
Guarantee the accuracy at effectively lower electric moment.
In a kind of optional embodiment of the embodiment of the present invention, controller can detecte the supply voltage of hard disk；At this
In the optional embodiment of the another kind of inventive embodiments, in the embodiment of the present invention before step 101, controller can also be obtained
The supply voltage for the hard disk for taking detection circuit to detect.
Wherein, detection circuit can be used for detecting the supply voltage of hard disk.Controller acquisition detection circuit detects hard
After the supply voltage of disk, the working condition of hard disk is determined based on the voltage value of acquisition.
As the present invention implement in a kind of determining hard disk do not power on duration method specific embodiment, controller can be with
It is connect respectively with timing circuit, detection circuit.Clocking capability may be implemented in timing circuit, and controller is allow to need to record firmly
When each moment of disk working condition, the time for needing to record is obtained by timing circuit.Timing circuit can be set in hard disk
On, and powered by independent battery, to can also work when hard disk does not power on.Detection circuit can be used to detect hard disk
Supply voltage allows controller and determines based on the supply voltage that detection circuit detects the working condition of hard disk.
