Abstract

Provided is a method for accessing media files that are separated and stored in a plurality of data sectors and processing bad sectors in a mobile communication terminal with a hard disk drive, the method comprising: storing in a plurality of data sectors The media file of the media file generates an access request event; the address of the first data sector to be accessed is designated as the access index indicating the address to be accessed; try to access the data sector located at the access index within a predetermined time, and when the access is successful When, read the media data from the data sector of successful access, when the access fails, write the predetermined default data to the data sector of failed access; determine whether there is a next data sector to be accessed, when it is determined When there is a next data sector to be accessed, the access index is incremented by 1 and the data sector at the increased access index is accessed.

Description

technical field [0001] The present invention generally relates to a method of processing a specific data sector detected as a bad sector in a hard disk mobile communication terminal. More specifically, it relates to a method of writing predetermined default data into a bad sector and overcoming the incapable access state when the bad sector is detected. Background technique [0002] Generally, a mobile communication terminal refers to a device for wirelessly communicating with a base station and having a main call function. However, current mobile communication terminals have been added with supplementary functions for processing multimedia information in addition to basic voice call functions. In other words, the mobile communication terminal can include a camera for processing image data and perform supplementary multimedia functions such as running music files and providing an electronic dictionary. Therefore, a mobile communication terminal req...
