Abstract:
1. A method for processing noise interference in a data accessing device with a SATA (Serial Advanced Technology Attachment) interface, the method comprising: an error detecting step for detecting whether there is a CRC (Cyclic Redundancy Check) error, whether an reception error primitive (R_ERR primitive) is received, whether an improper primitive is received, or whether a LINK layer error is detected; a type detecting step for detecting whether an FIS (Frame Information Structure) is a data type FIS; a step for detecting whether the FIS is a ATAPI CDB (Command Descriptor Block) when the FIS is the data type; and a step for setting a special mark on the CDB, or on any ATAPI Register if the FIS contains a CDB when there is an error.
