6.2. SCSI Physical Interface
All Western Digital SCSI hard drives are designed to conform to the SCSI-3 Parallel
Interface as described in the draft of proposed ANSI specification X3T10/855D Revision
15a. In addition, drives equipped with the 80-pin SCA connector are designed to
conform to the Small Form Factor Committee draft specification SFF-8046 Rev 2.0
entitled “SCA-2 (Single Connector Attach) for SCSI Disk Drives”. Since tutorials on
SCSI-3 and SCA are beyond the scope of this manual, users should review their SCSI
implementations as required to ensure compliance. The SCSI-3 spec has several
informative annex sections on cabling, bus termination, crosstalk, etc., that are quite
helpful to SCSI system architects and implementors.
