SELF-TESTING DATA STORAGE DEVICES AND METHODS

摘要

Systems and methods for self-testing archival memory devices are described. The memory device includes a data storage component capable of being coded with data. The memory device further includes a read-write mechanism configured to read, write, and delete data stored on the data storage component. The memory device includes a read-write controller configured to control the read-write mechanism based on input received through a device interface of the memory device, wherein the device interface of the memory device is configured to connect to an external computing device. The memory device further includes a diagnostic controller configured to perform a test on at least one of the data stored on the data storage component, the data storage component, and the read-write mechanism. The memory device includes a power source configured to provide operational power to the diagnostic controller when the memory device is not connected to an external power source.

1. A method of testing a data storage system in an archival state, the method comprising:
powering a diagnostic controller of the data storage system with a power source of the storage system, wherein the data storage system is configured to be connected to a computing device; detecting, by the diagnostic controller, a trigger event; performing, by the diagnostic controller and based on detection of the trigger event, a test on the data storage system; and determining a result of the test; wherein the diagnostic controller is separate from the computing device.
