The alternate directory block is a "backup copy" of the main directory and is used if the directory block becomes damaged. The volume name in the alternate directory is only updated when the disk is formatted and not when you change the volume name. All the other information in the alternate directory block is updated correctly. Any time you change your hard drive name Norton will report this minor error.
This is a cosmetic problem and does not affect the operation of your computer. There is no directory damage. The discrepancy between the volume names in the two directories on your new Power Macintosh computers occurred when the software bundle on your hard drive was created on a disk with a name other than "Macintosh HD" and the name was changed to "Macintosh HD" before the disk was cloned.
