If the drive is the last device on the SCSI chain, make sure that the 

SCSI cable is terminated correctly.

and SCSI Cables

Termination must be present at two and ONLY two positions on the SCSI 

bus—at the beginning of the SCSI bus and at the end of the SCSI bus. 

Termination is normally enabled by default on the HBA and most 

internal SCSI cables have a terminator attached. This will usually be a 

small, rectangular block of plastic attached to the cable end and marked 

‘SCSI Terminator’.
