Abstract

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;

wherein detecting the trigger event includes receiving, by the diagnostic controller, a feedback signal from a detection circuit of the data storage system;

wherein the feedback signal is indicative of a sensed physical characteristic associated with the data storage system;

wherein the sensed physical characteristic includes at least one of a temperature, a humidity, a motion, or a magnetic field; and

wherein the test on the data storage system is a diagnostic test including a functional test of movement of at least one of a motor or a head assembly of the data storage system.

2. The method of claim 1, wherein the detection circuit includes a sensor.

3. The method of claim 2, wherein detecting the trigger event includes determining that the sensed characteristic exceeds a threshold value.

4. The method of claim 2, wherein detecting the trigger event includes determining that a time integral of a function of the sensed characteristic exceeds a threshold value.

5. The method of claim 2, wherein the sensor includes at least one of at least one of a temperature sensor, a humidity sensor, a vibration sensor, a motion sensor, and a magnetic field sensor.

6. The method of claim 1, further comprising receiving, by the diagnostic controller, an indication of a time, a date, and/or a status of a running timer from a timer of the memory storage system.

7. The method of claim 6, wherein the trigger event is a specific time and/or a specific date.

8. The method of claim 1, further comprising initiating an alert or a message to an external computing device and/or to a user through a communication interface of the data storage system.

9. The method of claim 8, wherein the message includes a time of the test, a type of the test, a result of the test, and/or a recommended course of action.

10. The method of claim 8, wherein the communication interface includes a human-perceivable indicator.

11. The method of claim 10, wherein the human-perceivable indicator includes a light source, and wherein the message is presented through the light source such that the message is perceivable by a person.

12. The method of claim 10, wherein the human-perceivable indicator includes a speaker, and wherein the message is presented as an audible alert through the speaker.

13. The method of claim 10, wherein the human-perceivable indicator includes a display.

14. A method of indicating a need for testing of a memory storage system in an archival state, comprising:

powering a notification circuit of the memory storage system with a power source of the memory storage system;

detecting, by the notification circuit, a trigger event;

providing, by the notification circuit and through a communication interface of the memory storage system, an alert external to the memory storage system that indicates a need for performing a diagnostic test of the memory storage system based on detection of the trigger event; and

receiving, by the notification circuit, a feedback signal from a detection circuit of the memory storage system;

wherein the feedback signal is indicative of a sensed physical characteristic associated with the memory storage system;

wherein the sensed physical characteristic includes at least one of a temperature, a humidity, a motion, or a magnetic field; and
