Abstract: A method for analyzing the reliability of a flag value carried by a current block is disclosed. The method includes: determining whether the current block is a dummy block, and determining the flag value as invalid if the current block is determined as a dummy block. The step of determining the current block is a dummy block can be implemented through two methods. The first method is to utilize information (signal quality indicators) of the current block and a previous block to perform the dummy block determination. The second method is to only utilize information (including the signal quality indicators and coded USF correction indicators) of the current block to generate a determination value through substituting the information into a predetermined equation, and to perform the dummy block detection according to the determination value.

Abstract: This invention provides a method for managing digital data and the digital data allocation in a memory, which is applied to a digital recording device. The memory can repetitively write and crase and comprises a plurality of sectors in which a plurality of digital data files can be written. The least unit to crase the digital data in the memory every time is one sector. Each sector divides to a plurality of blocks, and each block is arranged a block header. The block header can record the current status of the corresponding block. The method comprises a step to set up a block reclamation starting condition. When some blocks in a target sector have to be erased, the digital data of the other blocks which need not to be erased will be moved and stored in the blocks of other sectors.
