First, ensure that the termination is set correctly and that the SCSI cable is in good working order.
Disable the BIOS or BIOS scan for the SCSI ID.
In order to disable BIOS, access the SCSI and then select the configuration utility by pressing Ctrl+A, when you are prompted during the boot process.
Go to the Advanced Configuration Settings menu, scroll to find the BIOS Support for Int 13 Extensions option, and set the option to Disabled.
Selectively disabling some performance-boosting options - Domain Validation, Packetized SCSI, and Quick Arbitration and Selection (QAS) may also improve the time necessary to complete a BIOS scan.
These troubleshooting steps should help you in isolating the problem. It is always recommended to have the user's manual handy. If nothing works then call the vendor for support.
