I was also facing such kind of issue in that case i try to remove any SCSI or serial devices attached to your computer for that you need to turn the computer off by pressing the power switch on the back of the computer and then disconnect any devices attached to the computer's external SCSI and serial (printer and modem) ports. Now wait for few seconds, this allows time for the hard disk drive to stop spinning. Turn the computer on by pressing the power switch on the back of the computer.

If you are still facing any issue after unplugging all SCSI then try to Start up from a CD-ROM disc that contains system software for your computer, or a Disk Tools floppy disk. Then run Disk First Aid to make sure that the hard disk is OK. Then test the hard disk using Apple HD SC Setup or Drive Setup.
