Internal Drives: Choosing the Internal option will select your drive to be pre-tested prior to shipping by OWC trained technicians. The pre-testing process includes the spinning up of the unit, pre-formatting using Mac OS HFS Plus* (extended) with Charismac Anubis Drive Utility Software, and the loading of 100mb of shareware onto the drive. The shareware titles include everything from basic Hard Drive utility programs to system diagnostic utilities, Newer Tech's "Guru", and even some classic Macintosh promotional videos. Order with confidence and ensure ease of installation by choosing the Internal option with your next drive from OWC!

Bare Drives: Choosing the bare option skips the drive pre-testing as well as formatting. This option gets your drive shipped faster but leaves the "Tech Issues" in your hands.

External Drives: Choosing this option will get you everything you get with the Internal Drive Option, but your drive will be installed in an external enclosure. Power cable, SCSI connecting cable, and terminator are included with all external drives.

  • Bare Hard Drives ship without delay
  • Please allow 1-2 day processing for Internal/External Hard Drives

* If you have a Macintosh model that is running Mac OS 7 or earlier, please call in your order and ask for custom formatting of the drive using HFS Standard.
