Method and system for preventing unreliable data operations at cold temperatures
View Patent ↗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.
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, the HDD communicatively coupled to an information handling system; and
issuing a read command from the information handling system if the first internal temperature is below the threshold temperature, the read command requesting that data be read from a track of the HDD;
disregarding the data returned from the HDD based on the read command so that the data is not read by the information handling system.
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 resuming 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 read command causes one of a random seek, a butterfly seek, a ⅓ stroke seek, and a sequential seek.
9. The method of claim 1 , wherein the threshold temperature is provided by a user.
10. 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:
initiate a read from a track of the HDD in response to a read command from an information handling system communicatively coupled to the HDD if the signal indicates that the first internal temperature is below a threshold temperature; and
disregard the data returned from the HDD based on the read command so that the data is not read by the information handling system.
11. The HDD of claim 10 , wherein the temperature sensor is further configured to transmit a second internal temperature following a pre-defined time interval.
12. The HDD of claim 11 , 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.
13. The HDD of claim 12 , 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.
14. The HDD of claim 11 , wherein the pre-defined time interval is substantially based on an event.
15. The HDD of claim 11 , wherein the pre-defined time interval is provided by a user.
16. The HDD of claim 10 , further comprising a third component configured to spin the HDD up to a target revolutions per minute (RPM).
17. The HDD of claim 10 , wherein the read command causes one of a random seek, a butterfly seek, a ⅓ stroke seek, and a sequential seek.
18. The HDD of claim 10 , wherein the threshold temperature is provided by a user.
19. 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;
issue a read command requesting that data be read from a track of the HDD if the first internal temperature is below the threshold temperature; and
disregard the data returned from the HDD based on the read command so that the data is not read.
20. The system of claim 19 , wherein the instructions are further configured to sample a second internal temperature of the HDD following a pre-defined time interval.
21. The system of claim 20 , 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.
22. The system of claim 21 , 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.
23. The system of claim 20 , wherein the pre-defined time interval is substantially based on an event.
24. The system of claim 20 , wherein the pre-defined time interval is provided by a user.
25. The system of claim 19 , wherein the instructions are further configured to spin the HDD up to a target revolutions per minute (RPM).
26. The system of claim 19 , wherein the read command causes one of a random seek, a butterfly seek, a ⅓ stroke seek, and a sequential seek.
27. The system of claim 19 , wherein the threshold temperature is provided by a user.
