Apple HD SC Setup 2.0 is able to update the drivers only on hard drives
formatted with HD SC Setup 2.0.
For example, if a hard disk was formatted with HD SC Setup 1.5 or earlier,
HD SC Setup 2.0 will NOT be able to update the drivers on that drive. Apple
HD SC Setup 2.0 is completely compatible with System Software 6.0.2.
It's okay to use versions of HD SC Setup older than version 2.0 with System
Software 6.0.2, but we recommend using the latest version of HD SC Setup
whenever possible.
