Drives are no longer available from the manufacturer.
The original Apple PowerBook series was produced with 40MB to 350MB hard drives. Although that size was large at the time of original production, current systems and programs require much more hard disk space. During 1995-1996, Apple Computer began installing IDE drives in the PowerBooks instead of the SCSI drive. Even though the IDE transfer rates are not as fast as SCSI, the decision to switch to IDE was purely economical. It kept the price of the PowerBook at a competitive level.
