Abstract:
A method and apparatus are provided for serial advanced technology attachment (SATA) hot unplug. In one embodiment, a method includes detecting a connection of a SATA storage device to a SATA host interface by monitoring physical (PHY) layer signals derived from SATA communication terminals, by a controller of the host interface. The detection being based on phase locked loop (PLL) response of the PHY layer signals. The method further includes detecting disconnection of the SATA device based on the PLL response and outputting a notification, by the controller, when the PLL response indicates that the SATA device has been disconnected.
