Abstract

Systems and methods for reducing problems and disadvantages associated with protecting data during cold excursions are provided. A method for preventing unreliable data operations at cold temperatures may include determining whether a first internal temperature of a hard disk drive (HDD) is below a threshold temperature. The method may also include initiating an artificial seek operation if the first internal temperature is below the threshold temperature.

Claims (33)

1. A method for preventing unreliable data operations at cold temperatures comprising:

determining whether a first internal temperature of a hard disk drive (HDD) is below a threshold temperature; and

initiating an artificial seek operation if the first internal temperature is below the threshold temperature, the artificial seek operation comprises one of a random seek, a butterfly seek, and a sequential seek.

2. The method of claim 1 , further comprising sampling a second internal temperature of the HDD following a pre-defined time interval.

3. The method of claim 2 , further comprising pausing a read/write operation if the second internal temperature of the HDD is below the threshold temperature.

4. The method of claim 3 , further comprising proceeding with the read/write operation if the second internal temperature of the HDD is above the threshold temperature.

5. The method of claim 2 , wherein the pre-defined time interval is substantially based on an event.

6. The method of claim 2 , wherein the pre-defined time interval is provided by a user.

7. The method of claim 1 , further comprising spinning the HDD up to a target revolutions per minute (RPM).

8. The method of claim 1 , wherein the threshold temperature is provided by a user.

9. A hard disk drive (HDD) comprising:

a temperature sensor configured to transmit a signal corresponding to a first internal temperature; and

a component configured to perform an artificial seek operation if the signal indicates that the first internal temperature is below a threshold temperature, the artificial seek operation comprises one of a random seek, a butterfly seek, and a sequential seek.

10. The HDD of claim 9 , wherein the temperature sensor is further configured to transmit a second internal temperature following a pre-defined time interval.

11. The HDD of claim 10 , further comprising a second component configured to pause a read/write operation if the second internal temperature of the HDD is below the threshold temperature.

12. The HDD of claim 11 , wherein the second component is further configured to proceed with the read/write operation if the second internal temperature of the HDD is above the threshold temperature.

13. The HDD of claim 10 , wherein the pre-defined time interval is substantially based on an event.

14. The HDD of claim 10 , wherein the pre-defined time interval is provided by a user.

15. The HDD of claim 9 , further comprising a third component configured to spin the HDD up to a target revolutions per minute (RPM).

16. The HDD of claim 9 , wherein the threshold temperature is provided by a user.

17. An information handling system comprising:

a processor;

a hard disk drive (HDD) communicatively coupled to the processor; and

a computer-readable medium communicatively coupled to the processor and having stored thereon instructions configured to, when executed by the processor:

determine whether a first internal temperature of the HDD is below a threshold temperature; and

initiate an artificial seek operation if the first internal temperature is below the threshold temperature, the artificial seek operation comprises one of a random seek, a butterfly seek, and a sequential seek.

18. The system of claim 17 , wherein the instructions are further configured to sample a second internal temperature of the HDD following a pre-defined time interval.

19. The system of claim 18 , wherein the instructions are further configured to pause a read/write operation if the second internal temperature of the HDD is below the threshold temperature.

20. The system of claim 19 , wherein the instructions are further configured to proceed with the read/write operation if the second internal temperature of the HDD is above the threshold temperature.

21. The system of claim 18 , wherein the pre-defined time interval is substantially based on an event.

22. The system of claim 18 , wherein the pre-defined time interval is provided by a user.

23. The system of claim 17 , wherein the instructions are further configured to spin the HDD up to a target revolutions per minute (RPM).

24. The system of claim 17 , wherein the threshold temperature is provided by a user.
