Why can't you see your files?

This hard disk is formatted with the Mac OS Extended format. Your files and information are still on the hard disk, but you cannot access them with the version of system software you are using.

How can you access your files?

To access your files you must mount this hard disk on a computer that has Mac OS 8.1 or later installed. To determine the version of system software you're currently using, choose About this Computer from the Apple Menu. If you're using a version of the Mac OS earlier than 8.1, you must do one of the following:

A) Updgrade the system software on this computer

B) Start up the computer from a hard disk or CD that has Mac OS 8.1 or later

C) Connect the hard disk to another computer with Mac OS 8.1 or later installed.

If you want to access the files without upgrading your operating system, start your computer with the Mac OS 8.1 CD, or the Disk Tools for PPC disk, then access your files. The System Folder on the CD and Disk Tools for PPC disk supports the Mac OS Extended format. Apple recommends that you have the Mac OS 8.1 CD if you plan to reformat any hard disk using Mac OS Extended format

To continue to use this hard disk on this computer, you must updgrade your system software to Mac OS 8.1.
