Embodiment 1

[0044] like figure 1 Shown is a hard disk firmware repair system provided by this embodiment, including a central control chip 105, a hard disk data interface 106, and a host computer 103;

[0045] The upper computer 103 is connected with the central control chip 105, and is used to send a firmware reading instruction to the central control chip 105; Contrast, if inconsistent then send the pre-stored intact firmware module to the central control chip 105;

[0046] The central control chip 105 is connected with the hard disk 101 through the hard disk data interface 106; the central control chip 105 is used to send the firmware reading instruction to the hard disk data interface 106; the central control chip 105 is also used For sending the received firmware module to the host computer 103; the central control chip is also used for sending the received complete firmware module to the hard disk data interface;

[0047] The hard disk data interface 106 reads the firmware module ...

Embodiment 2

[0064] When the hard disk firmware repairing system of the above-mentioned embodiment is in use, at first it is necessary to establish a data path between the hard disk and the present invention, and this step includes:

[0065] First, connect the PCI-E interface to the PCI-E slot of the host computer, and connect the input end of the hard disk power controller to the chassis power interface of the host computer; then, respectively connect the hard disk power controller and the hard disk data interface through the hard disk power cable 1. The data line is connected to the power supply and data interface of the hard disk, thereby completing the physical connection between the hard disk firmware repair system of the present embodiment and the hard disk to be tested; then under the control of the host computer, the hard disk is sent to the central control chip through the PCI-E interface. The power-on command completes the power-on operation of the hard disk through the hard disk ...

Embodiment 3

[0077] like figure 2 As shown, the present embodiment provides a hard disk firmware repair method using the above hard disk firmware repair system, including the following steps:

[0078] 201. The upper computer sends a firmware reading instruction to the central control chip;

[0079] 202. The central control chip sends the firmware read instruction to the hard disk data interface;

[0080] 203. The hard disk data interface reads a firmware module in the hard disk according to the firmware reading instruction, and sends the read firmware module to the central control chip;

[0081] 204. The central control chip sends the received firmware module to the upper computer;

[0082] 205. The host computer compares the received firmware module with the pre-stored intact firmware module, and if inconsistent, sends the pre-stored intact firmware module to the central control chip;

[0083] 206. The central control chip sends the received intact firmware module to the hard disk dat...

Abstract

The invention relates to the field of programmable logic devices and embedded devices, and in particular relates to a hard disk firmware repairing system and a hard disk firmware repairing method. The hard disk firmware repairing system comprises a PCI-E (programmable communication interface-express) interface, a hard disk power supply controller, a hard disk data interface, a principal computer and a central control chip; the PCI-E interface is respectively connected with the central control chip and the principal computer; the input end and the output end of the hard disk power supply controller are respectively connected to the principal computer and a hard disk, and a control end is connected to the central control chip; a control end of the hard disk data interface is connected to the central control chip, and a data transmitting-receiving end is connected to the hard disk. By adopting the hard disk firmware repairing system, the problem that the hard disk cannot be recognized by the principal computer and the breakdown maintenance or data extraction is difficultly carried out due to the damage of the hard disk firmware or the bad track of the hard disk can be solved; through the control of the hard disk firmware repairing system, the data which is not damaged in the hard disk can be recognized and read, so that the hard disk firmware repairing success rate and the data extracting efficiency can be improved.

Description

technical field [0001] The invention relates to the field of programmable logic devices and embedded devices, in particular to a hard disk firmware repair system and a hard disk firmware repair method. Background technique [0002] In the prior art, after the firmware in the hard disk is damaged, the host computer cannot recognize the hard disk because the host computer cannot directly read the damaged firmware in the hard disk. The hard disk maintenance and other operations need to connect the faulty hard disk directly to the computer motherboard. The access to the hard disk is completely dependent on the host computer operating system and hardware environment. To repair the hard disk failure, the hard disk must be recognized by the host computer. next. [0003] At present, it is impossible to identify and repair the hard disk after the firmware is damaged. Contents of the invention [0004] The purpose of the present invention is to provide a hard disk firmware repair ...
