Method and system for preventing unreliable data operations at cold temperatures
First Claim
Patent Images
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.

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.

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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

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. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
