Phdisk is a disk utility used with portable computers that saves information to a hard drive hibernation partition if the computer runs out of power. Phdisk allowed users to turn off their computer to switch batteries or connect the portable to the wall without losing anything currently running. Today, files are used in place of the hibernation partition because of various issues caused by the partition.
