Data storage device and method for performing error recovery

A data storage device, comprising:

• an interface circuit, configured to process reception signals received from a peer device and transmission signals to be transmitted to the peer device, wherein the interface circuit comprises a signal processing circuit configured to perform an error recovery procedure when an error has occurred in the data storage device, and
• when performing the error recovery procedure, the signal processing circuit determines to perform an operation of line reset and determines which type of line reset is to be performed according to a device identifier,
• when the device identifier satisfies a predetermined condition, the signal processing circuit performs an operation of periodic line reset to repeatedly transmit a line reset signal to the peer device in a predetermined period until the predetermined period expires or another line reset signal representing an acknowledgment of the line reset signal is received from the peer device, and
• when the device identifier does not satisfy the predetermined condition, the signal processing circuit performs an operation of one-shot line reset to transmit the line reset signal to the peer device for only one time.
