A method for processing noise interference in a serial AT Attachment
(SATA) interface. The method includes the steps of detecting whether
there is an error in CRC (Cyclic Redundancy Check) checksum or whether an
R_ERR primitive (reception error primitive) is received, detecting
whether a FIS (Frame Information Structure) is a data type if there is
any error and returning back to error state detecting step if there is no
any error, detecting whether the FIS is a ATAPI packet command CDB
(Command Descriptor Block) when the FIS is the data format, and writing a
special tag to the CDB and returning back to the error detecting step.
