Repairing method for hard disk after firmware accessing is closed

Abstract

The invention discloses a repairing method for a hard disk after firmware accessing is closed. The repairing method includes the steps that resource files of the hard disk are loaded to obtain a NV-RAM and an IDNT module of the hard disk, the firmware version numbers in the NV-RAM are compared with the firmware version numbers of the IDNT module, and data losing of the firmware version numbers in the NV-RAM is determined, and is different from that of the firmware version numbers of the IDNT module; data of the firmware version numbers in the NV-RAM is modified, a verifying value of the NV-RAM is set as zero, and the modified NV-RAM is written back the hard disk, and can be identified by a computer; a fault hard disk is effectively repaired accordingly, and the manpower-and-material-resource consuming problem caused by the direct disassembling method, the magnetic head replacing method and the like and in disassembling operation, replacing operation and the like, the hard-disk fault expansion problem, the hard-disk secondary damage problem and the hard-disk complete damage problem which are caused by human factors are solved.

Description

technical field [0001] The invention belongs to the field of data restoration, and relates to a repair method of a hard disk, in particular to a repair method after the hard disk is closed for firmware access. Background technique [0002] As an important member of storage devices, hard drives play an extremely important role. Most of our data is stored through hard disks. This phenomenon of large-scale use of hard disks to record data is even dubbed "civilization based on magnetic media". Therefore, the sharp increase in data storage and the importance of data , making data recovery even more important. [0003] Hard disk data recovery is divided into three levels: namely, physical layer, firmware layer and logical layer. At these three levels, if failures at the physical layer or firmware layer cannot be resolved, effective analysis and recovery at the logical layer cannot be performed. In the prior art, there are many methods for analyzing and restoring the logical lay...

AI Technical Summary

Problems solved by technology

[0004] When the hard disk cannot be recognized by the computer because the access to the firmware area of ​​the NV-RAM is closed, for example, important information such as its parameters and capacity cannot be recognized, so that the data on the hard disk cannot be accessed, the maintenance personnel often take methods such as direct disassembly and replacement of the magnetic head. , not only consumes manpower and material resources, but also often causes the expansion of hard disk failure due to human factors, causing secondary damage to the hard disk, and even causing complete damage to the hard disk.
