SMART is used to measure your HDD health.It warns you of impending failure of your hard drive. If it goes down, it's a good idea to backup important stuff and prepare to replace the HDD.

S.M.A.R.T is an acronym for Self-Monitoring, Analysis and Reporting Technology systems (SMART) and it's usually built in to most modern ATA and SCSI hard disks.

The hard drive needs to be set as the first SCSI ID device boot device..
The hard drive needs to have the jumper set to SCSI ID 0, the CD and FDD can be set to SCSI ID 1 and SCSI ID 2. No SCSI devices can have the same SCSI ID number unless it is on a different SCS controller.

There are two ways of retrieving data from a SCSI hard drive.
1. Connect the SCSI hard drive to a different SCSI connector on the same data cable, make sure this hard drive has a different SCSI ID from the first hard drive or other SCSI devices in your system. When you boot up your MAC you should see the second SCSI hard drive, You can then copy off your data or remove the redundant files and keep the old hard drive in your system as a 2nd hard drive.
2. Connect the old SCSI hard drive to a SCSI USB hard drive adapter. Then connect it to the USB port on the MAC and you should see this as an external hard drive.

The SCSI driver is required to installed during the initial boot up for installation when additional drivers are asked .the new models dont come with a Floppy drive so an external floppy drive can be used .The detection of HDD s must be at the startup by the Bios os SCSI card.

hi
Checked the Bios Setting and check whether the Hard drive is recognizing or not -
Check the Boot sequence
Check Boot from the CD Drive
Format the Hard drive
it will work

If possible check it out on another computer.
This will then establish one or the other which is misbehaving.
Then come back
