Abstract: A data storage device includes a first memory section with a reserved area having stored therein an event trigger log that includes a history of past logged events. The data storage device also includes a second memory section separate from the first memory section. The data storage further includes a controller that, upon power up of the data storage device and before the data storage device is ready to receive host commands, allocates a buffer in the second memory section for capturing new events. The controller postpones linking of any captured new events with the past logged events until at least after the data storage device is ready to receive the host commands.
