NOTES: The contents of the hard disk will be erased when the HDD troubleshooting
procedures are executed. Before running the procedures, transfer the contents of the
hard disk to a floppy disk as follows.
Check to see if the Microsoft Create System Disks Tools (MSCSD.EXE) still exists
in the System Tools Folder. (This tool can be used only once.) If it exists, use it to
back up the preinstalled software, then use the Backup utility in the System Tools
Folder to back up the entire disk, including the user's files.
Refer to the appropriate instructions for each operating system.
