I have a 1.5-year-old WD 5400RPM 40GB HDD. It makes a loud sharp metallic whine when it runs (louder than my very loud case fans). It also vibrates very hard (I know for sure it's the drive, not anything else in the computer). The 20GB "C" partition also fails to format when I use the format command on the Win98 boot floppy. Is my drive dying?
