APPARATUS AND METHOD FOR SORTING DISK COMMANDS ON ENERGY USED BY THE DISK COMMANDS

For each seek command of a plurality of seek commands of a hard disk drive, a correction value is determined that adjusts an access time of the seek command. The correction value includes a scaling factor that adjusts an energy variable. The scaling factor is based on a power target of the hard disk drive, and the energy variable may represent an energy used in the seek command as a time value. The seek commands are sorted in a command queue by the adjusted access times. The seek commands are executed by a controller of the hard disk drive based on the sorting within the command queue.
