TOPIC

    This article tells how your computer's hard disk drivers may be downgraded to an earlier version during a custom installation of a Mac OS 8.5 component, and how to work around the issue.

DISCUSSION

    By default, the Mac OS 8.5 installer will "Update Apple Hard Disk Drivers". Since Mac OS 8.5 was released before the Mac OS 8.5.1 Update and Drive Setup 1.6.2, the Mac OS 8.5 installer may downgrade the hard disk drivers to older versions. To avoid this issue, you should do either of the following:

    1) If updated drivers have already been installed using Drive Setup 1.6.2 or newer, deselecct the "Update Apple Hard Disk Drivers" option in the Mac OS 8.5 installer before reinstalling or custom installing software. This option is accessed by clicking the "Options..." button in the installer window.

    2) If the drivers are accidentally downgraded by the Mac OS 8.5 installer, run the Drive Setup 1.6.2 (or newer) application again to update the hard disk drivers to the latest version.

    NOTE: You can tell which version of the hard disk driver you have by selecting your hard disk volume in the Finder and choosing "Get Info" from the File menu to bring up the Get Info window. The information next to "Where" usually gives you the driver version you are using. For example,

    Where: My Hard Disk, (ATA Bus 0 Dev 0, v3.14)
    or
    Where: My Hard Disk, Bus 1, SCSI ID 0 (v8.1.0)
