Problems solved by technology

[0002] As the world's largest hard disk manufacturer, Seagate hard disks produced by Seagate can be seen everywhere. The firmware that manages the capacity of the hard disk and the firmware that manages the defects of the hard disk are easily damaged in daily use, resulting in the inability to recognize the hard disk capacity.
Existing technology can only deal with technical faults where the capacity is cut, but it is currently impossible to identify and repair the hard disk after the firmware is damaged

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0034] A method for repairing abnormal capacity of a Seagate hard disk, comprising the following steps:

[0035] S1: The hard disk enters the command mode, enters the T-level mode, enters the 1-level mode, restores the SMART table, if the restoration fails, execute S2, and if the restoration is successful, execute S3;

[0036] Call functions:

[0037] UART0_Sendchar(0x1A); / / Enter command mode

[0038] IRQ_READ_UART0(); / / Read data to buffer

[0039] checkF3T(); / / Check whether the buffer data is F3T>

[0040] ClearSmart()

[0041] {

[0042] UART0_SendBuf(" / 1"); / / Enter level 1 mode

[0043] UART0_SendBuf("N1");

[0044]}

[0045] If(isERR==false) exit; / / exit

[0046] S2: restore hard disk Congen parameters;

[0047] Call functions:

[0048] ReductionCongen()

[0049] {

[0050] U...

Abstract

The invention discloses a method for restoring a capacity abnormity of a Seagate hard disk. The method comprises the following steps of: S1: the hard disk entering an instruction mode, a T-level mode and a 1-level mode, reducing an SMART table, if a reduction error occurs, executing the step S2, or if the reduction is successful, executing the step S3; S2: reducing a Congen parameter of the hard disk; S3: clearing a G table; and S4: restoring hard disk capacity. The method has the beneficial effects as follows: the hard disk capacity attempts to be restored in four different modes, and the success rate of restoration is high due to the application of stepped restoration means; and the problems that LBA is equal to 0 and LBA is equal to 1 can be dealt with and the capacity abnormity problem not caused by the fact that the capacity is shorn can be solved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for repairing abnormal capacity of a Seagate hard disk. Background technique [0002] As the world's largest hard disk manufacturer, Seagate hard disks produced by Seagate can be seen everywhere. The firmware for capacity management and hard disk defect management in hard disks is easily damaged in daily use, resulting in the inability to recognize the hard disk capacity. Existing technology can only deal with technical failures in which the capacity is cut, but it is currently impossible to identify and repair hard disks with damaged firmware. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a method for repairing the abnormal capacity of the Seagate hard disk, which can effectively solve the above-mentioned problems in the prior art. [0004] In order to realize above object of the invention, the ...
