APM Tuner is allows you to adjust the Advanced Power Management Value (APM Value) for hard disks in the internal ATA bus and expansion bays of recent PowerBooks.

Advanced Power Management is a feature found in hard disks for portable usage aimed at conserving power. However, APM can effect the user experience, creating a sense of "lag" or clunking sounds when the head is parked. By increasing the APM Value, the drive will "park" its heads less often. The result is a more responsive drive with less "clunking."


MacOS 8.5 or later, FireWire Powerbook.
