Method for pre-heating hard disk drive of computer device
First Claim
1. A method for pre-heating a hard disk drive of a computer device, wherein the computer device comprises a power supply device, a microprocessor, the hard disk drive, and a data memory unit, a temperature sensor being arranged at a preset location on the hard disk drive to detect a hard-disk external temperature of the hard disk drive, a heater being arranged at a preset location on the hard disk drive, the data memory unit storing at least one hard-disk activation temperature threshold and a preset compensation value, the hard-disk activation temperature threshold being a lowest safety temperature that the power supply device is allowed to supply power to the hard disk drive, the preset compensation value being defined as a preset difference between the hard-disk external temperature and a hard-disk internal temperature, the method comprising the following steps:
- (a) starting up the computer device;
(b) detecting the hard-disk external temperature of the hard disk drive by the temperature sensor;
(c) determining relative level of the hard-disk external temperature and the hard-disk activation temperature threshold by using the microprocessor;
(d) allowing the power supply device to supply power to the heater for heating the hard disk drive and prohibiting activation of the hard disk drive when a result of the hard-disk external temperature subtracting the preset compensation value is less than the hard-disk activation temperature threshold; and
(e) allowing the power supply to supply power to the hard disk drive and also allowing activation of the hard disk drive when a result of the hard-disk external temperature subtracting the preset compensation value is equal to the hard-disk activation temperature threshold.

Abstract
Disclosed is a method for pre-heating a hard disk drive of a computer device, wherein a temperature sensor and a heater are arranged at preset locations outside the computer device. The temperature sensor detects an external temperature of the hard disk drive, which is compared with an activation temperature threshold stored in a data memory unit of the computer device. The activation temperature threshold is calibrated by a preset compensation value stored in the data memory unit. When the external temperature of the hard disk drive subtracting the preset compensation value is less than the activation temperature threshold of the hard disk drive, the activation of the hard disk drive is prohibited and the heater carries out heating on the hard disk drive until the activation temperature threshold of the hard disk drive is reached; thereafter, the hard disk drive is activated again. Thus, the hard disk drive is protected from damage caused by excessively low internal temperature of the hard disk drive at the time when the hard disk drive is activated.
