As shown in figure 1, Fig. 1 is a kind of schematic diagram of a scenario of disk control according to an exemplary embodiment：In Fig. 1
In the scene shown, storage device includes multiple disks, also, storage device is provided with foreground program and background program.First,
User can input the detection cycle of setting by the foreground program of storage device.Foreground program obtains the detection week of user's input
Phase, and the detection cycle is stored.Then, foreground program can send detection request, detection request to background program
It is middle to carry default detection cycle and detection configured information.
Then, after background program receives detection request, timing is started using timer, detected when timer reaches
During the cycle, it may be determined that detection moment reaches.When detection moment reaches, during background program can ask further according to detection
The detection configured information of carrying travels through each disk and detected, so as to detect disk in default operating condition and not
Disk in default operating condition.The disk of default operating condition will be not in as target disk.Wherein, if disk exists
In RAID (Redundant Arrays of Independent Disks, disk array) group, or if disk be in read/
Write state, then illustrate that disk is in default working condition.
Finally, background program control is not in the target disk of default operating condition and enters resting state, and to foreground journey
Sequence returns to control result.If background program successfully controls disk to enter resting state, return to disk to foreground program and enter
The result of resting state.If background program controls disk to enter resting state not successfully, report an error and disappear to foreground program return
Breath.
As shown in Fig. 2 Fig. 2 is a kind of flow chart of magnetic disc control method according to an exemplary embodiment, the party
Method can apply in terminal device, can also be applied in server.This method comprises the following steps：

Each disk is detected, to determine to be not in the target disk of default operating condition.
In the present embodiment, when detection moment reaches, the detection that background program carries in being asked according to detection refers to
Show that information detects to each disk, to determine the state of each disk.Any one disk may be at default work shape
State, non-default working condition can also be in.The disk of default operating condition can will be not in as target disk, so as to examine
Measure the target disk in multiple disks.
In the present embodiment, the detection configured information carried in being asked in the following way according to detection is to the disk
Row detection：Disk is detected whether in disk array RAID groups according to detection configured information, if disk in RAID groups, is somebody's turn to do
Disk is in default working condition.Also, whether read/write status is according to detection configured information detection disk, if magnetic
Disk is in read/write status, then the disk is also at default working condition.
In step 204, background program control targe disk enters resting state.
In the present embodiment, after detecting to be not in the target disk of default operating condition in multiple disks, can control
Target disk processed enters resting state.For example, target disk magnetic head is placed in into rest area, or the rotating speed of target disk is reduced,
Or stop the rotation of target disk etc..
The magnetic disc control method that above-described embodiment of the application provides, sending detection to background program from foreground program please
Ask, default detection cycle is carried in detection request and detection configured information, background program are asked in response to detection, according to
The detection cycle carried in detection request determines whether detection moment reaches.When detection moment reaches, background program is according to inspection
Survey in request the detection configured information carried to detect each disk, to determine to be not in the target magnetic of default operating condition
Disk, background program control targe disk enter resting state.So as to make the disk of idle state enter dormancy, save big
The electric energy of amount, cabinet heating is avoided, improve the service life of equipment.
As shown in figure 3, Fig. 3 is the flow chart of another magnetic disc control method according to an exemplary embodiment, should
Method can apply in terminal device, can also be applied in server.This method comprises the following steps：
In step 301, foreground program obtains the detection cycle that user is set.
In step 302, foreground program is stored detection cycle.
In step 303, detection request is sent from foreground program to background program, default inspection is carried in detection request
Survey cycle and detection configured information.
In step 304, background program is asked in response to the detection, and the detection cycle carried in being asked according to the detection is true
Determine whether detection moment reaches.
In step 305, when detection moment reaches, background program is according to the detection configured information carried in detection request
Each disk is detected, to determine to be not in the target disk of default operating condition.
Within step 306, background program control targe disk enters resting state.
In step 307, if background program successfully controls disk to enter resting state, disk is returned to foreground program
Into the result of resting state.
In step 308, if background program controls disk to enter resting state not successfully, return and report to foreground program
Wrong message.
It should be noted that for the step identical with Fig. 2 embodiments, no longer gone to live in the household of one's in-laws on getting married in above-mentioned Fig. 3 embodiments
State, related content can be found in Fig. 2 embodiments.
The magnetic disc control method that above-described embodiment of the application provides, the detection week of user's setting is obtained by foreground program
