Method for realizing hard disk initialization, device and system thereof

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 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 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. 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 internal integrated circuit ...

AI Technical Summary

Problems solved by technology

At this time, multiple hard disks load configuration words through the I2C bus at the same time, causing confusion in the data transmission of the I2C bus, I2C communication failure, and hard disk initialization failure.
