My HD failed and was replaced by our local Mac store through AppleCare. I reinstalled the OS and then restored using Time Machine. I first booted from the installation disk and and tried to restore from 'Utilities' but my new HD wasn't recognized. Before the crash, when I opened Time Machine only 'Macintosh HD' was shown. After the restoration, when I open Time Machine, it shows 'Mac HD', 'Network', and 'Iomega'. Iomega is my external drive. Any ideas as to what is wrong? Is Time Machine now backing up the HD and the external drive? I did name the replacement 'Mac HD' rather than 'Macintosh HD'. Should I deselect 'Network' and 'Iomega' in Time Machine preferences? All else seems to be normal.
