My Mac freezes during startup when my 1394 device is attached to the FireWire port.
My Macintosh (running Apple OS 8.6 – 9.2.2) freezes during system startup when my 1394 Personal Storage/External Storage drive is attached to the FireWire port.
This error happens if you installed the optional Maxtor FireSCSI Extension Set at the same time you installed the Maxtor Utilities.
At the Apple Menu choose: Control Panels / Extensions Manager. From the View menu, select as Items. Click on the Name column (near the top of the Extensions Manager window). This will lists extensions in alphabetical order. Find the following extensions and uncheck each one to disable it from loading:
- FireSCSI Expert
- FireSCSI Maxtor Enabler
- FireSCSI RBC RAID Enabler
- FireSCSI Support
Shut down your Macintosh from the Special menu in the Finder. Boot up the computer again. Your Macintosh should now start up properly.
Note: The FireSCSI extensions must be enabled if you are using the QuickStripe RAID 0 functionality of the Maxtor Utilities and may be required for other manufacturers’ FireWire devices to function properly. Do not disable the FireSCSI extensions if you have set up a FireWire RAID with the Maxtor Utilities or if the FireSCSI extensions are required by another FireWire device. As a workaround, unplug your Maxtor Personal Storage drive from the FireWire port on your Mac before starting up the computer. Turn on your Mac, wait until it has completed the startup process, and then connect the drive to the FireWire port on the computer. The drive should be recognized properly by the system.
