Hard disk management method and device

Abstract

The invention provides a hard disk management method which is used for managing hard disk data fields and comprises the steps of: A, judging the type of a file to be read-written according to the attribute of the file to be read-written, determining the file as a first index file, executing the step B, determining the first index file as a data file and executing the step C, wherein the first index file is an index file used by a user; B, after the presence of a bad track in the sector of the first index file to be read-written is determined, selecting the alternative sector from a second index file to read and write, wherein the second index file is a vacant index file for backup; and C, after the presence of the bad track in the sector of the data file to be read-written is determined, performing read-write operation on the next section of the sector having the bad track. The invention further provides a hard disk management device. By adopting the method and the device provided by the invention, normal read-write can be performed on a hard disk under the situation that the hard disk has the bad track and is not formatted.

Description

technical field [0001] The invention relates to computer technology, in particular to a hard disk management method and management device. Background technique [0002] At present, hard disks are widely used in electronic products such as computers and video recorders as the main storage medium. The hard disk must be formatted before use; figure 1 As an example, briefly explain the structure of a hard disk using a file allocation table (File Allocation Table, FAT) file system, as follows: [0003] A hard disk formatted with the FAT file system includes: primary boot sector, first reserved sector, basic partition 1, second basic partition 2, basic partition 3 and basic partition 4. Wherein, the master boot sector stores a master boot program (MBR) and a partition table; the partition table stores entries of the above four partitions. Each basic partition includes a boot sector and a data area for storing file content; wherein, the boot sector stores an operating system boo...

Problems solved by technology

[0010] To sum up, when there are bad sectors in the data area of ​​the hard disk, normal read and write operations cannot be performed without formatting the hard disk.
