If you want to upgrade your computer to run Panther while continuing to use a FireWire 400 drive, follow these guidelines:
Back up everything on the drive to DVD, CD-R, tape, or some other medium other than another FireWire hard drive before installing Panther.
Check your drive manufacturer's Web site to see if a firmware update is available. If so, apply it (preferably before installing Panther) - even if the manufacturer does not mention whether the update addresses this issue.
If you are not installing Panther on the FireWire drive itself, disconnect the drive from your computer until after you have installed Panther and updated it to version 10.3.2 or later.
Avoid chaining FireWire devices together, especially if a chained device lacks its own power supply. If you have more FireWire 400 devices than your computer has ports, use a powered hub - or better yet, if you have a PowerBook or Power Mac, add a second FireWire bus using a PCI or PCMCIA card.
If you must use a FireWire 400 drive but cannot back it up or avoid chaining devices together, consider these additional precautions:
Be sure the drive's FireWire cable is unplugged when you turn on your computer.
Before shutting down, restarting, or putting your computer to sleep, unmount any volumes from the FireWire drive and unplug the drive's FireWire cable.
If your computer is set to sleep automatically, temporarily disable this feature in the Energy Saver pane of System Preferences.
Plug in the drive only when Panther is running. Again, be sure to unmount the disk and disconnect the FireWire cable when you finish using the drive.
