(First embodiment)
Storage Device FIG. 1 is a block diagram showing a schematic configuration of a magnetic disk device and a smartphone as an embodiment of the present invention. The magnetic disk device 100 according to the first embodiment is used as a so-called external storage device connected to the recording device 300 through a predetermined external connection interface. The external connection interface described above is a USB (Universal Serial Bus) in the present embodiment. Not only USB but also SCSI (Small Computer System interface), Fiber Channel, SATA (Serial Advanced Technology Attachment), SAS (Serial Attached SCSI), or LAN (Local Aware, or other interface). When using a LAN, the iSCSI protocol may be used. In this embodiment, it is used as an external storage device of the recording device 300, but may be used as an external storage device of a general personal computer. The data exchange performed by the external storage device is the same for both the recording device 300 and a general personal computer having a USB interface.

  The magnetic disk device 100 is driven by DC power supplied from an AC-DC adapter (not shown). Instead of the AC-DC adapter, it may be driven by power supplied from the USB interface, that is, power supplied by VBUS. The magnetic disk device 100 includes a control unit 10, a flash memory 20, a hard disk drive (HDD: hard disk) 30, a notification unit 50, a USB connector 60, and a Bluetooth (BlueTooth) module 70. In the case of a product, the hard disk 30 may be accommodated and connected in advance, or the purchaser may separately accommodate and connect the hard disk.

  The control unit 10 includes a CPU 11, a command input unit 12, a data amount specifying unit 13, a cumulative data amount calculating unit 14, a USB-SATA bridge unit 15, a data writing unit 16, a notification control unit 17, a SMART acquisition unit 18, and a data comparison. In addition to this, it has a RAM, a ROM, and a predetermined I / O circuit. The CPU 11 expands and executes a control program (storage device control program) stored in advance in the flash memory 20 on the RAM, thereby executing a command input unit 12, a data amount specifying unit 13, a cumulative data amount calculating unit 14, and a USB. -Functions as the SATA bridge unit 15, the data writing unit 16, the notification control unit 17, the SMART acquisition unit 18, and the data comparison unit 19. The flash memory 20 is used as a recording area for predetermined data in addition to being used as a recording area for a basic control program such as a storage device control program.

The command input unit 12 performs USB communication according to the USB standard via the USB connector 60 with the recording apparatus 300, and transmits / receives a SCSI command using the USB communication.
When exchanging SCSI comaside with the recording apparatus 300, the data amount specifying unit 13 transmits and receives data along with the command, more precisely, the amount of data written to the hard disk 30 and the reading from the hard disk 30. Specify the amount of data.

The accumulated data amount calculation unit 14 accumulates the values (transfer data amount) specified by the data amount specifying unit 13 and accumulates the transfer data amount from the start of operation of the magnetic disk device 100, that is, the accumulated workload. Calculate the value.
The USB-SATA bridge unit 15 converts the USB / SATA interface. In addition, the USB-SATA bridge unit 15 outputs the converted control command and processing target data to the hard disk 30 or the USB connector 60. Specifically, USB data input via the USB connector 60 is converted into SATA data and output to the hard disk access unit 31. The SATA data input from the hard disk access unit 31 is converted into USB data and output to the USB connector 60.

The data writing unit 16 writes the cumulative workload value to the flash memory 20 in the cumulative value writing process described later.
The notification control unit 17 controls the notification unit 50. Specifically, the LED 52 is turned on and off, and the buzzer 54 is turned on / off.
The SMART acquisition unit 18 transmits a command for acquiring smart information stored in the hard disk 30 and acquires smart information managed by the returned hard disk 30. Smart information is one piece of management information identified by an ID. By transmitting a command using the ID of management information to be acquired as a parameter, management information of the corresponding ID can be obtained. The smart information to be used will be described later.

  The data comparison unit 19 compares the management information with a predetermined threshold value. If the management information is information representing degradation per unit time, the difference between degradations per unit time is compared with a predetermined threshold, and if the management information is information representing degradation as a cumulative value, the management information Is compared with a predetermined threshold value.

SMART Information The hard disk 30 is a hard disk drive, and is a storage medium that includes a platter (corresponding to a storage area), a magnetic head, a hard disk access unit 31, and the like. The hard disk access unit 31 executes data writing to the platter and data reading from the platter (hereinafter referred to as “data access processing”). In addition to writing and reading data, the hard disk access unit records and manages error history, operation history, and the like at that time. Although there are various types of such management information, as an example, the following information (hereinafter referred to as SMART information) is used in the present embodiment.

1) The number of bad sectors (item ID: 05: Reallocated Sectors Count) that have been subjected to alternative treatment (moving to a reserved area where data has been specifically reserved).
2) The total number of sectors that are currently abnormal and waiting for substitution processing (item ID: 197: Current Pending Sector Count).
3) Total number of unrecoverable sectors found during offline scanning (item ID: 198: Off-Line Scan Uncorrectable Sector Count).
In addition, the number of times sector replacement processing has occurred (item ID: 196: Reallocation Event Count) may be employed.

  Although these numerical values can be directly compared with a predetermined threshold, in this embodiment, the amount of change per unit time is compared with a predetermined threshold. For example, the number of bad sectors that have been replaced is allowed to increase gradually. However, from the viewpoint of presenting the replacement time, it is important to increase the degree of increase in defective sectors. Therefore, the degree of change in the number of defective sectors, that is, the difference is determined every predetermined time. The remaining management information described above is also determined by the difference.

As described above, the smart information is information related to the state of the hard disk 30 as a storage medium, and is management information regarding the degree of use.
Thus, the storage medium is a hard disk drive, and the information related to the state of the storage medium is part of the smart information.

The workload data amount specifying unit 13 specifies the value set in the “TRANSFER LENGTH” (transfer data length) field in the READ command and WRITE command specified in the SCSI standard as the amount of data to be transmitted and received. . This “amount of data written to the hard disk 30 and a data amount read from the hard disk 30” will be referred to as “workload”. The recommended replacement timing of the hard disk 30 depends on the amount of data written to the hard disk 30 and the amount of data read from the hard disk 30.

When the command input unit 12 transmits / receives a SCSI command, the data amount specifying unit 13 specifies the amount of data transmitted / received together with the command, and the accumulated data amount calculating unit 14 transmits / receives this data amount (transfer data amount). The workload that is
Based on the control command output to the storage medium, the capacity of the recorded data (corresponding to the amount of transfer data) is accumulated to obtain management information. This process is executed by the control unit.

More specifically, the workload of this embodiment is information relating to the volume of recorded data that is read from and written to the storage medium.
Since the workload is a cumulative value of the transfer data amount from the start of operation of the magnetic disk device 100, the replacement time is determined by comparing the cumulative value itself with a predetermined threshold value rather than the difference per predetermined time. The workload is management information related to the capacity of recorded data to be read / written to / from the storage medium, and the recorded data to be read / written based on a SCSI command that is a control command communicated to the storage medium via the first communication unit. The capacity is accumulated and used as management information. As described above, the value can be calculated using the value of the “TRANFERLENGTH” field of the control command that is a SCSI command. Of course, this is not a limitation.

  The workload is information related to the state of the hard disk 30 that is the storage medium of the magnetic disk device 100, information related to its own state, and management information regarding the degree of use of the storage medium.

-Terminal device The smart phone 200 as a terminal device is a mobile communication terminal provided with the mobile communication module 210, and data communication is possible in addition to a voice call. In addition, a Bluetooth (BlueTooth) module 220 is provided, and can communicate with the Bluetooth module 70 through a predetermined procedure. The smartphone 200 has a display 230 and a touch panel 240 mounted on the surface of the display 230. The smartphone 200 is provided with a flash memory 260. The terminal control unit 250 of the smartphone 200 has a configuration for realizing functions as a computer such as a CPU 252, a ROM, and a RAM inside, and can execute a predetermined control program recorded in the flash memory 260 or the like. These devices are controlled by a terminal control unit 250 that performs comprehensive control, and functions such as a determination unit to be described later are realized.

First Control FIG. 2 is a flowchart corresponding to the control program for the magnetic disk device of this embodiment, and FIG. 3 is a flowchart corresponding to the control program for the terminal device of this embodiment. These control programs are recorded in the flash memory 20, the flash memory 260 of the smartphone 200, or the like. The CPU 11 of the magnetic disk device 100 and the CPU 252 of the smartphone 200 execute these control programs in parallel with other control programs.

  The magnetic disk device 100 is connected to the recording device 300 via a USB cable, and this USB connection becomes a communication path. The USB connector 60 and the USB-SATA bridge unit 15 that perform USB connection correspond to the first communication unit. The magnetic disk device 100 and the smartphone 200 can be connected wirelessly by the Bluetooth module 70 and the Bluetooth module 220, respectively. In the magnetic disk device 100, the Bluetooth module 70 that realizes a communication path other than the USB connection path is the second. Corresponds to the communication unit. The smartphone 200 corresponds to the second external device. The magnetic disk device 100 and the smartphone 200 are paired in advance to enable bidirectional signal transmission / reception.

As described above, the second communication unit performs communication conforming to the Bluetooth standard.
As shown in FIG. 2, the CPU 11 of the magnetic disk device 100 sets a timer in step S102. This is a criterion for determination in S108 described later. For example, the CPU 11 sets a predetermined time after a predetermined time to a timer variable or the like based on the current time, or sets a timer for measuring an elapsed time (not shown) to count from zero (timer reset).

  Next, in step S104, the CPU 11 determines whether there is a SCSI command waiting for processing. The recording apparatus 300 outputs commands and data to the USB connector 60 according to a predetermined operation. If there is an unprocessed SCSI command in the received command, the CPU 11 processes the SCSI command in step S106, and after the processing, determines again whether there is an unprocessed SCSI command in step S104. The magnetic disk device 100 connected to the recording device 300 receives and records the recording data in response to the recording data write request from the recording device 300, and reads the recorded recording data from the recording device 300. The recorded data is read from the hard disk 30 in response to the request. Such processing is realized by a SCSI command. Note that the recording device 300 corresponds to a first external device, and the hard disk 30 corresponds to a storage medium. Accordingly, such writing and reading of the recorded data corresponds to reading / writing of the recorded data to / from the storage medium with the first external device via the first communication unit.

A SCSI command may be followed by data, and processing of the SCSI command includes processing subsequent data.
If there is no unprocessed SCSI command, the CPU determines whether a predetermined time has elapsed in step S108. When a predetermined time after a predetermined time is set in the timer variable in step S102, it is determined whether or not the current time exceeds the predetermined time, that is, whether or not the predetermined time is exceeded. When the timer is reset, it is determined whether or not the current count value of the timer has passed a predetermined time.

  If the predetermined time has elapsed, the CPU 11 acquires the SMART information / workload cumulative value from the SMART acquisition unit 18 and the cumulative data amount calculation unit 14 in step S110, and in step S112, the flash memory 20 To record. When the predetermined information is recorded in the flash memory 20, the CPU 11 returns to step S102, resets the timer, and repeats the above-described processing. As described above, the CPU 11 updates the SMART information / workload cumulative value recorded in the flash memory 20 at that time in the processing of steps S108 to S112 after the predetermined time has elapsed.

The magnetic disk device 100 can obtain the amount of change per unit time by updating the SMART information / workload accumulated value at approximately constant time intervals. Therefore, this is equivalent to generating management information related to the degree of use of the storage medium, and the management information is communicated to the second external device via the second communication unit at a predetermined timing as will be described later.
Note that the amount of change can be substantially obtained by obtaining the SMART information / workload cumulative value updated approximately every certain time. However, at the time of communication, the amount of change of the SMART information / workload cumulative value is previously determined. Of course, it is also possible to calculate and communicate.

The flash memory 20 corresponds to a non-volatile memory, and the process of recording the SMART information / workload accumulated value in the flash memory 20 corresponds to the storage of information communicated to the second external device by the control unit in the memory. .
By using the timer, the SMART information / workload accumulated value is updated approximately every predetermined time, so that the amount of change per unit time can be calculated from the difference between the information before and after the update and the predetermined time. Note that it may be determined first whether a predetermined time has elapsed since the last SCSI command was processed, and the SMART information / workload accumulated value may be updated only when the predetermined time has elapsed. By doing so, the SMART information / workload cumulative value is acquired and recorded in the flash memory 20 during a period when communication is not performed via the first communication unit. Further, the processing corresponds to processing for acquiring information related to the state of the storage medium and storing it in the memory.

  If it is determined in step S108 that the predetermined time has elapsed, the SMART information / workload accumulated value is updated, and the timer variable is reset. If it is determined in step S108 that the predetermined time has not elapsed, the CPU 11 determines in step S114 whether there is a request for acquiring SMART information / workload accumulated value. This SMART information / workload cumulative value acquisition request is transmitted from the smartphone 200.

  Referring to FIG. 3, CPU 252 of smartphone 200 sets a timer in step S202. The specific method for setting the timer may be the same as described above. The smartphone 200 transmits a request for acquiring SMART information / workload accumulated value to the magnetic disk device 100 at regular time intervals, and thus the CPU 252 waits for a predetermined time to elapse in step S204. Of course, the smartphone 200 executes other processes in parallel with this process.

When waiting for the elapse of the predetermined time, the CPU 252 transmits an acquisition request for SMART information / workload accumulated value in step S206. The acquisition request is transmitted by Bluetooth communication.
In the magnetic disk device 100, when the CPU 11 recognizes the SMART information / workload cumulative value acquisition request in step S114, the SMART information / work at that time recorded in the flash memory 20 in step S116. Send load cumulative value. This transmission is also performed via Bluetooth communication. The SMART information / workload accumulated value is information related to the state of the storage medium, and is transmitted to the second external device via the second communication unit at a predetermined timing.
The operation of the second communication unit is independent from the operation of the first communication unit.

On the smartphone 200 side, the CPU 252 waits and receives the transmitted SMART information / workload cumulative value in step S208, and stores it in the internal memory in step S210. At this time, new information is recorded while leaving past information. In this way, the difference can be calculated.
In step S212, the CPU 252 performs a difference comparison. Since the smartphone 200 records past SMART information / workload accumulated value in addition to the latest information, the smart information is compared with a predetermined threshold value. Judge. When it is determined that there is an abnormality, the CPU 252 notifies in step S214. Note that the workload accumulated value is not a difference, but the accumulated value is directly compared with the threshold value as part of the determination in step S212.

  Since the smartphone 200 includes the display 230, the CPU 252 displays necessary information on the display 230. The display can also include other relevant information. As an example, while displaying that the connected devices are the recording device 300 and the magnetic disk device 100, it is further displayed that the replacement time for the hard disk 30 in the magnetic disk device 100 is approaching. It ’s fine.

The process of regularly communicating the SMART information / workload accumulated value via Bluetooth communication using a timer is equivalent to the control of communicating information related to the state of the storage medium via the second communication unit at a predetermined timing. To do.
The difference comparison process performed by the CPU 252 in step S212 performs various processes, but after receiving at least information related to the state of the storage medium via the second communication unit, all of the information is received. Alternatively, a part is compared with a predetermined threshold value, and as a result, it can be said that whether or not to notify is determined.

Conventionally, the abnormality of the hard disk 30 is indicated by the lighting of the LED 52 of the magnetic disk device 100 or the sound of the buzzer 54. However, the notification can be made only after the abnormality has occurred, and even the notification may be overlooked. It remained.
However, according to the present embodiment, since the information to be notified is displayed on the display 230 of a terminal device that the user uses on a daily basis, for example, a smartphone (including a mobile phone having a display), the risk of overlooking can be reduced. In addition, by displaying the information correlated with the replacement time before the occurrence of the abnormality, it is possible to notify at the time before the occurrence of the abnormality.

(Second Embodiment)
Second Control In the previous embodiment, the difference comparison process was performed on the smartphone 200 side. However, it can also be realized on the magnetic disk device 100 side. This embodiment corresponds to the latter.
FIG. 4 is a flowchart corresponding to the control program of the magnetic disk device of this embodiment, and FIG. 5 is a flowchart corresponding to the control program of the terminal device of this embodiment.

  The CPU 11 of the magnetic disk device 100 sets a timer in step S302, determines whether there is an unprocessed SCSI command in step S304, and if there is an unprocessed SCSI command, the SCSI command is detected in step S306. After processing, it is determined again in step S304 whether there is an unprocessed SCSI command. Such a series of processing is the same as in the first embodiment.

Also in the present embodiment, the CPU 11 determines in step S308 whether a predetermined time has elapsed, and when the predetermined time has elapsed, acquires the SMART information / workload accumulated value in step S310, and in step S312. , Recorded in the flash memory 20.
Thereafter, in step S320, the CPU 11 performs a difference comparison process. The difference comparison process corresponds to the process performed by the smartphone 200 in step S212.

In the first embodiment, the management information is acquired by the magnetic disk device, and it is the terminal device that determines the necessity of notification based on the management information. In the second embodiment, the magnetic disk device acquires management information and determines the necessity of notification based on the management information.
When there is a need for notification, it notifies itself and informs the terminal device of the result. It is the data comparison unit 19 that determines the necessity of notification based on the management information. The CPU 11 may substantially determine by software processing, or the data comparison unit 19 may be realized by hardware.

  Specifically, if the CPU 11 performs the difference comparison process in step S320 and determines that there is an abnormality, in step S324, the CPU 11 controls the notification unit 17 to control the lighting of the LED 52. The buzzer 54 sounds. Further, in step S326, the CPU 11 transmits the SMART information / workload cumulative value and the difference comparison result to the smartphone 200 using the Bluetooth communication using the Bluetooth module 70.

  On the other hand, on the smartphone 200 side, the CPU 252 determines whether the SMART information / workload accumulated value is received via the Bluetooth module 220 in step S402. As described above, in the second embodiment, the replacement time of the hard disk 30 is determined on the magnetic disk device 100 side. Therefore, when the CPU 252 of the smartphone 200 receives the SMART information / workload cumulative value, the replacement is performed. The time has come. For this reason, the CPU 252 records the received SMART information / workload cumulative value in the internal memory in step S404, and notifies it in step S406.

  The notification on the smartphone 200 corresponds to the display on the display 230. Of course, since it is often provided with an LED and a speaker (not shown), the CPU 252 of the smartphone 200 may perform the lighting of the LED and the generation of the ringing sound in addition to the display on the display 230.

(Third embodiment)
Third Control In this embodiment, an example in which the magnetic disk device 100 and the smartphone 200 can communicate with each other by the second communication unit and the magnetic disk device 100 is controlled by the smartphone 200 will be described.

FIG. 6 is a flowchart corresponding to the control program of the terminal device of the present embodiment, and FIG. 7 is a flowchart corresponding to the control program of the magnetic disk device of the present embodiment. In the present embodiment, the Bluetooth module 220 corresponds to a third communication unit.
The CPU 252 of the smartphone 200 displays a predetermined display on the display 230 in step S502. In step S504, the CPU 252 determines whether the connection release operation displayed on the display 230 has been performed based on the reaction of the touch panel 240.

The connection release operation is an example of an operation on the hard disk 30 which is also called unmount (removing the recognition of the storage medium so that the storage medium can be safely removed). Accordingly, an operation other than the connection release operation may be displayed on the display 230, and it may be determined which operation has been performed based on the reaction of the touch panel 240.
If it is a connection release operation, the CPU 252 transmits a connection release request, which means the connection release operation, to the magnetic disk device 100 by the Bluetooth module 220 in step S506.
Another example of the connection release operation is turning off the power of the magnetic disk device 100. With this power-off operation, the hard disk 30 can be safely removed.

As described above, the smartphone 200 communicates control information for the hard disk 30 that is a storage medium with the magnetic disk device 100 that is a storage device control apparatus via the third communication unit. Specifically, this control information is information for releasing connection with the first external device from the storage medium.
On the other hand, on the magnetic disk device 100 side, the CPU 11 determines in step S602 whether an operation request for the magnetic disk device 100 has been received by the Bluetooth module 70, and if received, further in step S604. It is determined whether it is a disconnection request. If it is a connection release request, in step S606, the CPU 11 outputs a command to release the connection to the hard disk 30, that is, to unmount it. Of course, as explained on the smartphone 200 side, it may be made to correspond to other operations.

(Modification)
In the above-described embodiment, a hard disk is used as a storage medium, but a storage medium other than a hard disk device is also applicable. In this case, although it is not necessarily smart information, the present invention can be applied to information in which the storage medium manages information relating to its own state that correlates with the replacement time. Since SSDs that are compatible with hard disk drives are also recommended for replacement, the present invention can also be applied to configurations in which HDDs are replaced with SSDs.

  For the second communication unit and the third communication unit, it is possible to use not only the Bluetooth standard but also other communication standards such as the WiFi standard. The smartphone 200 may be, for example, a tablet terminal connected to WiFi only or a wristwatch type terminal.

For the timer set, PoH (Power on Hour), which is one of smart information, can be used as a criterion for determination.
For example, the PoH after a predetermined time is set in the timer variable or the like with the current PoH as a reference for the timer variable or the like. The CPU 11 periodically checks the PoH of the hard disk 30 and determines whether PoH exceeds the count value of the timer variable.
The difference comparison may be performed by both the magnetic disk device and the terminal device.

  Incidentally, the data recorded by the magnetic disk device is not limited to the recorded data. Even when data other than the recorded data is recorded, it is possible to easily grasp the replacement time. For example, all data other than recorded data such as photographs, music, and documents may be included.

Needless to say, the present invention is not limited to the above embodiments. It goes without saying for those skilled in the art,
