11. A method for performing error recovery, applied in an error recovery procedure performed by a signal processing circuit when an error has occurred in a data storage device, comprising:
transmitting a first predetermined request signal to a peer device to try to trigger a first signal handshake procedure;
selectively performing a periodic line reset operation or an one-shot line reset operation according to a device identifier when determining that the first signal handshake procedure has failed;
performing the periodic line reset operation to repeatedly transmit a line reset signal to the peer device when the device identifier satisfies a predetermined condition; and
performing the one-shot line reset operation to transmit the line reset signal to the peer device for only one time when the device identifier does not satisfy the predetermined condition.
