Embodiment Construction

[0029] FIG. 2 is a flowchart of a method for realizing hard disk initialization in the present invention. As shown in Figure 2, it includes the following steps:

[0030] Step 201, reset all hard disks sharing the same I2C bus for initialization.

[0031] Step 202, releasing each hard disk one by one, so that each hard disk is initialized one by one.

[0032] In this step, each hard disk may be released one by one according to the time required for initializing each hard disk, so as to ensure that only one hard disk is initialized at a time.

[0033] The method described in the above process can realize the initialization of multiple hard disks under the same I2C bus without competition.

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

Abstract

The method comprises: resetting all hard drives commonly sharing an internal integration circuit I2C bus; one-by-one releasing each hard drive; one-by-one initializing each hard drive.

Description

technical field [0001] The invention relates to the technical field of computer systems, in particular to a method, device and system for realizing hard disk initialization. Background technique [0002] The initialization of the hard disk refers to: when the reset signal of the hard disk is valid, that is, when the reset signal generates a rising edge from low level to high level, it will be pre-saved in the Electrically Erasable Programmable Read-Only Memory (EEPROM, Electrically Erasable Programmable The hard disk configuration words in Read-Only Memory) are loaded into the working chip of the hard disk. [0003] FIG. 1 is a schematic diagram of a hard disk initialization process in the prior art. As shown in Figure 1, when the reset signal of the hard disk generates a rising edge from low level to high level, the hard disk configuration words pre-saved in EEPROM are loaded into the working chip connected to the hard disk, and the loading process passes through The inte...
