Abstract:
1. A method for protecting a storage device during a high-gravity event, the method comprising: receiving a high-gravity event warning signal; stopping data transmissions to the storage device over a serial data stream in response to the high-gravity event warning signal; transmitting a first HOLDE primitive to the storage device over the serial data stream, wherein the first HOLDE primitive indicates to the storage device to take protective action in response to the high-gravity event warning signal; determining that a HOLDA primitive has been received in response to the first HOLDE primitive, wherein the HOLDA primitive is transmitted by the storage device to acknowledge the receipt of the first HOLDE primitive; determining whether the high-gravity event is finished; and resuming the data transmissions to the storage device over the serial data stream when the high-gravity event is finished, or transmitting one or more additional HOLDE primitives to the storage device over the serial data stream when the high-gravity event is not finished and the HOLDA primitive has been received.
