な部品を使用しないため、誤動作することはない。Failures in file systems such as magnetic disk drives are greatly affected by ambient temperature. Generally, a program always logs failure information as one of the maintenance measures for a magnetic disk device. Based on the contents of this logging, measures are taken to switch to an alternative disk, but in the present invention,
The cooling effect is enhanced by controlling the rotation speed of the cooling fan using a program. Therefore, since parts such as a temperature sensor are not used, there is no possibility of malfunction.

のため。Maintenance measures are implemented based on the content of the above failure information. However, in the present invention, since the reliability of a magnetic disk drive is greatly affected by the ambient temperature, over time the ventilation holes become clogged with dust and the internal temperature rises. may be rising. For this reason, the reliability of the magnetic disk device 3 is reduced, and there is a possibility that a CRC error or the like may occur. For this reason.

せ、障害に至らない様防止することができる。If a failure such as a CRC error occurs among the failure information by the program, the information that can be recovered from the error will be checked.
The error retry count number is stored in a specified address of the memory 2, and when this count number reaches a specified value or more, the program issues a command to the voltage control 4 to increase the voltage supplied to the fan 6, thereby increasing the voltage supplied to the fan 6. By increasing the rotational speed of the magnetic disk drive 3 and lowering the ambient temperature of the magnetic disk drive 3, the influence of temperature on the magnetic disk drive 3 can be reduced and failures can be prevented.

低価格で信頼性を向上させるという効果がある。According to the present invention, there is no need for temperature sensors, temperature-voltage conversion circuits, etc. that were provided in conventional devices, and preventive measures against failures of magnetic disk devices can be realized at low cost.
This has the effect of improving reliability at a low cost.
