Method, apparatus for processing disk bad sector,and computer storage medium

An apparatus for processing a disk bad sector, comprising:

• a memory and at least one processor coupled to the memory, wherein the least one processor is configured to execute instructions stored in the memory to
• obtain a target disk that is to be processed, and detect bad sector data in the target disk, wherein the bad sector data comprises at least one element value used to represent a position of a bad sector in the target disk;
• divide a storage space of the target disk into a specified quantity of sub-areas in advance;
• determine, in the specified quantity of sub-areas, a target sub-area corresponding to each of the at least one element value in the bad sector data;
• combine two neighboring target sub-areas spaced from each other by an interval satisfying a specified condition, to obtain a plurality of combined areas;
• determine isolated areas in one or both of head portions and tail portions of each of the combined areas, and combine the combined areas with the isolated areas to serve as the bad sector areas obtained after the combination so as to obtain a usable area different from the bad sector areas in the target disk;
• determine, according to a detection result, whether the target disk is usable;
• in response to determining that the target disk is usable, divide the target disk into a plurality of partitions according to the usable area, combine the plurality of partitions into one volume, and use the volume obtained after the combination as a reconstructed storage space;
• and
• set an access parameter for the reconstructed storage space.

A non-transitory computer storage medium, wherein the computer storage medium is configured to store a computer program which, when executed by a processor, causes the processor to perform a method for processing a disk bad sector;

• wherein the method comprises:
• obtaining a target disk that is to be processed, and detecting bad sector data in the target disk;
• combining bad sector areas represented by the bad sector data, to obtain a usable area different from the bad sector areas in the target disk;
• and
• determining, according to a detection result, whether the target disk is usable, reconstructing storage space of the target disk based on the usable area if the target disk is usable, and setting an access parameter for the reconstructed storage space;
• wherein the bad sector data comprises at least one element value used to represent a position of a bad sector in the target disk;
• and combining bad sector areas represented by the bad sector data comprises:
• dividing the storage space of the target disk into a specified quantity of sub-areas in advance;
• determining, in the specified quantity of sub-areas, a target sub-area corresponding to each of the at least one element value in the bad sector data;
• combining two neighboring target sub-areas spaced from each other by an interval satisfying a specified condition, to obtain a plurality of combined areas;
• and
• determining isolated areas in one or both of head portions and tail portions of each of the combined areas, and combining the combined areas with the isolated areas to serve as the bad sector areas obtained after the combination;
• wherein the reconstructing storage space of the target disk based on the usable area comprises:
• dividing the target disk into a plurality of partitions according to the usable area;
• and
• combining the plurality of partitions into one volume, and using the volume obtained after the combination as the reconstructed storage space.
