I received a rattling noise from the floppy disk which incidently goes away when the hard disk starts (ticking).
searching floppy drive for boot disk before finding boot files on external. (no problem) Change boot order to stop floppy drive search.
The Maxtor is making a noise like a clock ticking
Sounds as if you have corrupt boot files on the master disk. A repair install should overcome that problem
Do the above before attempting anything else.
