1. A method for controlling temperature in a hard disk drive during testing, the hard disk drive having two modes of operation, the method comprising:
- setting a desired temperature range for a hard disk drive that is being tested;
upon determining that a temperature inside the hard disk drive is below the desired temperature range, changing a mode of operation of the hard disk drive from a first mode of operation to a second mode of operation, wherein the first mode of operation generates less heat than the second mode of operation; and
upon determining that the temperature inside the hard disk drive is above the desired temperature range, changing the mode of operation of the hard disk drive from the second mode of operation to the first mode of operation.

Abstract
A method and program product supporting adjusting a temperature of a hard disk drive (HDD) during testing. An HDD test program is performed within a pre-determined optimal test temperature range. The HDD is kept within this pre-determined test temperature range by switching HDD operation modes back and forth between a higher heat generating Rapid Seek Mode and a lower heat generating IDLE mode. The HDD is thus kept within the optimal test temperature range without the use of external heating and/or cooling devices.

6. A method for maintaining a steady-state internal temperature inside a housing for a hard disk drive during testing operations of the hard disk drive, the hard disk drive having two modes of operation, the method comprising:
-
setting a desired temperature range for a hard disk drive that is being tested;
upon determining that a temperature inside the hard disk drive is below the desired temperature range, changing a mode of operation of the hard disk drive from a first mode of operation to a second mode of operation, wherein the first mode of operation generates less heat than the second mode of operation; and
upon determining that the temperature inside the hard disk drive is above the desired temperature range, changing the mode of operation of the hard disk drive from the second mode of operation to the first mode of operation. - View Dependent Claims (7, 8, 9, 10)

11. A method for rapidly warming up a hard disk drive before testing the hard disk drive having a first and second mode of operation, the method comprising:
-
setting a desired temperature range for a hard disk drive that is to be tested; and
upon determining that a temperature inside the hard disk drive is below the desired temperature range, setting a mode of operation of the hard disk drive to a first mode of operation, wherein the first mode of operation generates more heat than a second mode of operation, until the desired temperature range is reached. - View Dependent Claims (12, 13, 14, 15, 17, 18, 19, 20)

16. A computer program product, residing on a computer usable medium, for controlling temperature in a hard disk drive during testing, the computer program product comprising:
-
program code for setting a desired temperature range for a hard disk drive that is being tested;
program code for, upon determining that a temperature inside the hard disk drive is below the desired temperature range, changing a mode of operation of the hard disk drive from a first mode of operation to a second mode of operation, wherein the first mode of operation generates less heat than the second mode of operation; and
program code for, upon determining that the temperature inside the hard disk drive is above the desired temperature range, changing the mode of operation of the hard disk drive from the second mode of operation to the first mode of operation.
