Furthermore, the information processing apparatus 100 includes a power supply controller 152, a power supply apparatus 154, and a hard disk apparatus 160 that is an example of a storage device.

  The CPU 140 is a control unit that controls the entire system of the information processing apparatus 100. For example, the CPU 140 performs various arithmetic processes for executing an OS (Operating System) stored in the main memory 146, an application program running on the OS, and the like.

  The chip set 142 is a circuit that controls data exchange between devices such as the CPU 140, the main memory 146, the BIOS ROM 148, the I / O controller 144, the input unit 112, and the display unit 122. The I / O controller 144 controls data exchange with the hard disk device 160.

  The main memory 146 stores programs and data processed by the CPU 140. The main memory 146 also functions as a work area for the CPU 140. The BIOSROM 148 stores a BIOS (Basic Input / Output System).

  The power supply controller 152 controls power supply by the power supply device 154. The power supply device 154 supplies power to various internal components.

  The hard disk device 160 is used as an external storage device of the information processing apparatus 100. The hard disk device 160 mainly exchanges data with the main memory 146 via the I / O controller 144 and the chipset 142 under the control of the CPU 140.

The software driver also checks the error status of the hard disk device 160.

(1-3. Functional Configuration of Hard Disk Device)
An example of the functional configuration of the hard disk device 160 will be described with reference to FIG. FIG. 3 is a block diagram illustrating an example of a configuration of logical functions of the hard disk device 160 according to an embodiment.

  As illustrated in FIG. 3, the hard disk device 160 includes a hard disk 202 that is an example of a main memory, a cache memory 204 that is an example of a temporary storage memory, a SMART (Self-Monitoring Analysis and Reporting Technology) 206, and a control circuit 210. And have. As shown in FIG. 3, the control circuit 210 includes a data transfer unit 212, a verify processing unit 214, a parameter setting unit 218, and a setting change unit 220.

(Hard disk 202)
The hard disk 202 stores an OS and various application programs, and also stores document data files and image data files generated by the various application programs. The hard disk 202 has a storage area divided into a plurality of areas. Each divided area stores different types of data.

  FIG. 4 is a schematic diagram illustrating an example of a storage area of the hard disk 202 according to an embodiment. The storage area of the hard disk 202 is arranged from the outer periphery to the inner periphery of the circular disk. As shown in FIG. 4, the storage area of the hard disk 202 includes a startup area Pa1, a recovery area Pa2, a system area Pa3, and a data area Pa4.

  The activation area Pa1 is a portion (sector) that is placed at the beginning of the storage area of the hard disk 202 and is read first when the information processing apparatus 100 is activated. The activation area Pa1 also includes information on a logical block address (LBA) that designates a sector for storing data.

  The recovery area Pa2 is an area for OS recovery, and stores data and programs for recovery. The System area Pa3 is an area for accessing the OS at startup.

  The data area Pa4 is the largest area of the hard disk 202, and stores data such as an OS, application programs, and files. The data area Pa4 is further divided into a plurality of areas such as an area for storing the OS and an area for storing application programs.

(Cache memory 204)
The cache memory 204 temporarily stores data written from the main memory 146. Data in the cache memory 204 is overwritten sequentially. The cache memory 204 stores a command (processing instruction) related to the data together with the data to be stored. For example, a DRAM or the like is used as the cache memory 204.

  Data temporarily stored in the cache memory 204 is written to the hard disk 202. It should be noted that the data stored in the cache memory 204 is maintained until it is overwritten after being written to the hard disk 202.

(SMART206)
The SMART 206 is a function provided in the hard disk 202 for the purpose of finding a failure of the hard disk device 160 and predicting the failure. The SMART 206 self-diagnose various inspection items in real time and digitizes the state.

  FIG. 5 is a diagram illustrating an example of various inspection items included in the SMART 206 according to the embodiment. As shown in FIG. 5, each inspection item is given an ID (ID (A) or the like). The inspection items include, for example, an error rate, the number of rewrites, the temperature of the hard disk device 160, and the like.

  In the present embodiment, the CPU 140 of the information processing apparatus 100 accesses the SMART 206 and acquires information on the inspection item. For example, the CPU 140 periodically acquires the number of rewrites in the SMART 206 and determines whether or not the number of rewrites is a predetermined number or more. That is, the CPU 140 has a function of a rewrite state acquisition unit that acquires a rewrite state of data to the hard disk 202.

  When the number of rewrites is equal to or greater than the predetermined number, the CPU 140 changes setting conditions for parameters (described later) that are setting information for the verify process. Thereby, the setting condition can be changed to reflect an error in writing data to the hard disk 202. In addition, when the number of rewrites is a predetermined number or more, the CPU 140 may cause the display unit 122 to display information related to data writing to the hard disk 202. As a result, the user can easily perceive a state such as a data write error in the hard disk 202 by viewing the information displayed on the display unit 122.

(Control circuit 210)
The control circuit 210 is a microcomputer composed of, for example, a CPU and controls the operation of the entire hard disk device 160. For example, the control circuit 210 performs a verify process (details will be described later) for checking a write error of the hard disk 202 in order to ensure the accuracy and reliability of data writing to the hard disk 202.

(Data transfer unit 212)
The data transfer unit 212 writes the data stored in the main memory 146 into the cache memory 204. In addition, the data transfer unit 212 writes the data stored in the cache memory 204 to the hard disk 202. That is, the data transfer unit 212 writes the data in the main memory 146 into the hard disk 202 after temporarily storing the data in the cache memory 204.

  When the data transfer unit 212 writes data to the cache memory 204, the data in the cache memory 204 is overwritten.

(Verify processing unit 214)
The verification processing unit 214 performs verification processing using the data in the cache memory 204 and the data in the hard disk 202.

  Here, the flow of the verify process will be described. After the data is written from the cache memory 204 to the hard disk 202, the verify processing unit 214 reads the data in the cache memory 204 and the hard disk 202, and determines whether the data contents match. Next, when the verify processing unit 214 determines that the data is different, the verify processing unit 214 writes the data from the cache memory 204 to the hard disk 202 again. Then, the verify processing unit 214 repeats data writing and reading until the data in the cache memory 204 and the hard disk 202 match. By performing the above verify process, even if a write error occurs in the hard disk 202, the error can be eliminated.

  The verify processing unit 214 performs a verify process on the data written in a predetermined range in the storage area of the hard disk 202. This is because if the entire range of the storage area of the hard disk 202 is used as a target, the data writing time of the hard disk 202 becomes longer, and the processing performance deteriorates. The predetermined range is set by a parameter setting unit 218 described later.

  For example, the verify processing unit 214 targets a predetermined range for storing data important in the operation of the hard disk device 160 (for example, the startup area Pa1 shown in FIG. 4 and the area for storing the OS in the data area Pa4). A verification process is performed on the data stored in the predetermined range. As a result, reliability of data important in the operation of the hard disk device 160 can be ensured, and a decrease in processing performance of data writing to the hard disk device 160 can be suppressed. It is also possible to reduce the probability of occurrence of a fatal error such as the OS not starting.

  The verify processing unit 214 controls the verify process according to the number of commands stored in the cache memory 204. Specifically, the verify processing unit 214 does not execute the verify process when the number of commands stored in the cache memory 204 is larger than a predetermined number, and does not execute the verify process when the number of commands is smaller than the predetermined number. Execute the process. When the number of commands is large, the load on the hard disk device 160 is large, so that the verify process is not executed from the viewpoint of reducing the load.

  For example, since the number of commands is small at the beginning of data writing to the hard disk 202, the verify processing unit 214 actively executes the verify processing. At the beginning of data writing, a malfunction of the hard disk 202 is likely to occur due to dust adhering to the hard disk 202. However, even if a malfunction of the hard disk 202 occurs, the verification process is performed to perform the verification of the hard disk 202. Write errors can be eliminated.

  FIG. 6 is a schematic diagram illustrating an example of a command stored in the cache memory 204 according to an embodiment. Note that both commands and data are stored in the cache memory 204, but for convenience of explanation, only the commands are shown in FIG. In FIG. 6, four commands Co1 to Co4 are stored. When the above-mentioned predetermined number is set to 3, the number of commands is larger than the predetermined number, so the verify processing unit 214 does not execute the verify process. The predetermined number is set by a parameter setting unit 218 described later.

  The verify processing unit 214 controls the verify process according to the operation time of the hard disk device 160. For example, as shown in FIG. 7A, the verify processing unit 214 performs a verify process every time the operation of the hard disk device 160 starts until a predetermined time (time t1 shown in FIG. 7A) elapses from the start of activation. It is also possible not to perform. Since the startup process is performed when the operation of the hard disk device 160 is started, it is possible to suppress an increase in the time required for startup by not performing the verification process until the predetermined time t1 (time required for the startup process) has elapsed. . FIG. 7 is a schematic diagram showing the relationship between the operation time of the hard disk device 160 and the verify process.

  Further, as shown in FIG. 7B, the verify processing unit 214 does not perform the verify processing when the total operation time of the hard disk device 160 has passed a predetermined time (time t2 shown in FIG. 7B). It is also good. If there is no rewrite operation for a long period of time, there is a low possibility of falling into a failure mode that requires verification. Therefore, performance degradation can be suppressed by not performing verification processing.

(Parameter setting unit 218)
The parameter setting unit 218 sets parameters that are setting information related to the execution of the verify process based on the state and operation of the hard disk 202. The parameter setting unit 218 outputs the set parameter information to the verification processing unit 214. By setting the parameters in this way, the verify process can be executed at a timing suitable for the state and operation of the hard disk 202.

  The parameter which is setting information defines a predetermined range (for example, the recovery area Pa1 shown in FIG. 4 and the area in which the OS is stored in the data area Pa4) in which data to be verified is written in the storage area of the hard disk 202. Contains information. The parameter includes information defining the number of commands stored in the cache memory 204 that can be verified. The parameters include information that defines the timing for performing the verify process during the operation period of the hard disk device 160. For example, the parameters define an operation time t1 (FIG. 7A) of the hard disk that does not execute the verify process and an operation time t2 (FIG. 7B) that executes the verify process.

(Setting change unit 220)
The setting change unit 220 changes the parameter condition set by the parameter setting unit 218 when the rewrite count reaches a predetermined number or more and receives a parameter change command from the CPU 140. Thereby, it is possible to change to a more optimal parameter condition by referring to the data writing state of the hard disk 202.

  For example, the setting changing unit 220 widens or narrows a predetermined range to be verified in the storage area of the hard disk 202 (see FIG. 4). The setting changing unit 220 also changes the number of commands stored in the cache memory 204 that executes the refining process. The setting changing unit 220 also changes the operation time t1 (FIG. 7A) of the hard disk that does not execute the verify process and the operation time t2 (FIG. 7B) that executes the verify process.

  In the above description, the notebook personal computer having the built-in hard disk device 160 is described as an example of the information processing apparatus. However, the information processing apparatus is not limited to this. For example, the information processing apparatus may be a mobile phone, a PDA, a game machine, an electronic dictionary, a tablet, or the like as long as it has a built-in HDD.

<2. Example of operation of information processing apparatus>
Next, an operation example of the information processing apparatus 100 having the above-described configuration will be described.

  FIG. 8 is a flowchart illustrating an operation example of the information processing apparatus 100 according to an embodiment. The flowchart shown in FIG. 8 is executed when data stored in the main memory 146 is written to the hard disk 202 via the cache memory 204.

  First, the verify processing unit 214 stores data written from the cache memory 204 to the hard disk 202 in a predetermined range (for example, the activation area Pa1 and the data area Pa4 shown in FIG. 4) in the storage area of the hard disk 202. It is determined whether or not data has been written to (area) (step S102). For example, the verify processing unit 214 refers to the logical block address of the data to determine whether the data has been written within a predetermined range of the storage area.

  When the data is written in the predetermined range in step S102 (Yes), the verify processing unit 214 determines whether or not the number of commands stored in the cache memory 204 is equal to or less than the predetermined number (step S104). On the other hand, if the data is written outside the predetermined range in step S102 (No), the verify processing unit 214 turns off the verify processing (step S110).

  If the number of commands is less than or equal to the predetermined number in step S104 (Yes), the verify processing unit 214 determines whether or not the operation time of the hard disk device 160 satisfies a predetermined condition (step S106). Here, the predetermined condition refers to the case where the elapsed time from the start of activation of the hard disk device 160 has passed the predetermined time t1 (FIG. 7), or the total operation time of the hard disk device 160 is the predetermined time t2 (FIG. 7). ). On the other hand, when the number of commands is larger than the predetermined number in step S104 (No), the verification processing unit 214 turns off the verification processing (step S110).

  If the operation time satisfies the predetermined condition in step S106 (Yes), the verify processing unit 214 executes a verify process (step S108). That is, the verify processing unit 214 reads data from the hard disk 202 and the cache memory 204 and performs a match determination. On the other hand, when the operation time does not satisfy the predetermined condition in Step S106 (No), the verification processing unit 214 turns off the verification processing (Step S110).

  In the above description, three determinations (steps S102, S104, and S106) are performed. However, the present invention is not limited to this. For example, only one or two of the three determinations may be made.

  FIG. 9 is a flowchart illustrating an operation example of the information processing apparatus 100 according to an embodiment. The flowchart in FIG. 9 is executed at predetermined intervals during the operation of the hard disk device 160.

  First, the CPU 140 determines whether or not the number of rewrites in the SMART 206 of the hard disk 202 is equal to or less than a predetermined number (step S202). If the number of rewrites is less than or equal to the predetermined number in step S202 (Yes), the process described below is not executed.

  If it is determined in step S202 that the number of rewrites is greater than the predetermined number (No), the CPU 140 displays a message prompting the user to change the parameter setting conditions for the verification process on the display unit 122, as shown in FIG. It is displayed (step S204).

  FIG. 10 is a diagram illustrating a display screen example by the display unit 122 according to an embodiment. The display screen S1 of FIG. 10 includes a window Wi1 indicating a message that causes a write error of the hard disk device 160 and prompts the user to change parameter setting conditions. When the user clicks the OK button B1 in the window Wi1, a display screen S2 including a window Wi2 as a setting screen for changing the frequency of the verification process is displayed.

  In the window Wi2, an adjustment bar B2 for adjusting whether the user attaches importance to the processing performance or the reliability of written data is shown. When the user operates the adjustment bar B2, the parameters of the verification process are changed. When the parameter setting condition is changed by the user, the CPU 140 outputs the change information to the setting changing unit 220 of the hard disk device 160.

  Returning to FIG. 9, the description will be continued. When the parameter setting condition for the verification process is changed by the user, the setting changing unit 220 changes the parameter condition set by the parameter setting unit 218 (step S206). Thereby, referring to the data writing state of the hard disk 202, it is possible to suppress the performance degradation of the processing such as data writing while ensuring the reliability of the data writing to the hard disk 202 and the like. Can be changed.

  In addition, although the example shown in FIG. 10 was demonstrated as the display screen displayed by step S204 above, it is not limited to this. For example, the display example shown in FIG. 11 may be used. The display screen S3 shown in FIG. 11 includes a window Wi3 as a screen including a message that causes a write error of the hard disk device 160 and prompts the user to back up (recommend) data. FIG. 11 is a diagram illustrating an example of a display screen by the display unit 122 according to an embodiment.

<3. Summary>
The information processing apparatus 100 according to an embodiment acquires information related to a rewrite state in which data is rewritten to the hard disk device 160 without matching the data, and setting related to execution of a verify process based on the acquired information related to the rewrite state Change information. As a result, the verification process can be performed based on the setting information changed according to the rewrite state. For example, when the reliability of data is ensured from the rewrite state, the verification process is excessively performed by reducing the frequency of the verification process. It is possible to prevent the processing from being executed. As a result, it is possible to suppress deterioration in performance of processing such as data writing while ensuring reliability of data writing to the hard disk device 160 and the like.

  FIG. 12 is a schematic diagram showing the relationship between the processing time of the verification process, the risk of the hard disk device 160, and the processing load of the hard disk device 160 according to an embodiment. As shown in FIG. 12, in the information processing apparatus 100 according to an embodiment, a verify process is performed immediately after the start of data writing to the hard disk device 160. Immediately after the start of data writing, the risk of the hard disk device 160 is high. Therefore, the reliability of data writing to the hard disk device 160 can be ensured by performing the verify process. On the other hand, since the processing load on the hard disk device 160 is small immediately after the start of data writing, the performance of the hard disk device 160 is unlikely to deteriorate even if the verify process is performed.

  Further, when time elapses from the start of data writing, the risk of the hard disk device 160 is reduced, while the processing load on the hard disk device 160 is large, so the verification process is not performed. Further, when the end of data writing is approached, the number of processing commands decreases and the processing load on the hard disk device 160 decreases, so that the verify processing is executed. As shown in FIG. 12, by controlling the execution of the verification process, the reliability of data writing to the hard disk device 160 is efficiently utilized by utilizing the time lag between the risk of the hard disk device 160 and the peak of the processing load.
