Method for carrying out defect isolation during connection of defect hard disk and PC (Personal Computer) side

Abstract

The invention discloses a method for carrying out isolation during the connection of a defect hard disk and a PC (Personal Computer) side, and belongs to the field of hard disk data recovery. The method comprises the following steps: 001: the PC side sends a custom instruction which is obtained in a way that an original instruction is changed; and 002: the changed custom instruction is received and analyzed to be reduced to the original instruction. When equipment is connected with a PC system, the equipment can not directly access any data information of storage equipment and must be combined with a corresponding software system to transfer and interact with virtual protection to finish data interaction on the hard disk. The method adopts a defect isolation technology to effectively isolate the hard disk with defects from the PC, and an operating system can be prevented from loading the startup code of the defect hard disk so as to avoid a phenomenon that a PC upper-level system is crashed since the PC system loads the startup code of the hard disk.

Description

technical field [0001] The invention relates to the field of hard disk data recovery, in particular to a method for defect isolation when a defective hard disk is connected to a PC. Background technique [0002] When the PC is connected to the hard disk, the PC will directly use the read ATA command to access the hard disk and read the data of the hard disk. If the data volume of the hard disk is too large, the hard disk may be stuck. cause the hard drive to freeze. [0003] In the prior art, the method of mounting the operating system on the PE is generally used to extract the data of the defective hard disk, or the method of remounting the defective hard disk on the operating system to extract the data of the defective hard disk, but the above method does not use isolation Direct access to the hard disk will also cause a stuck situation. For the above situation, there is no good solution for the time being. Contents of the invention [0004] Aiming at the deficiencies...
