The Tape Disk Utility cannot reside in the System Folder of your startup disk if either MacroMaker or CloseView (utilities in Macintosh system software) is also in that System Folder. (If you upgrade your system software to Version 6.0 or higher, be sure to verify that neither MacroMaker nor CloseView is in the startup System Folder with Tape Disk.)
We recommend that you use the Tape Disk Utility and the Tape Backup software from a 3.5-inch startup disk and that you do not use Tape Disk with MultiFinder.
If you want to listen to audio with the AppleCD SC while doing a backup, you must use AppleCD SC Version 2.0 or greater.
