7.1.6 TROUBLE SHOOTING
Items required for diagnosis
• GGS1030: Operation check program (Diagnose5)
• GGV1035: DVD-ROM (Single/DVDT-001)
• GGV1036: DVD-ROM (Dual/DVDT-002)
• GGV1027: CD-ROM (CDT-304)
• GGV1231: Recorded DVD-R (8x DISC)
• GGV1232: DVD-R blank disc (8x DISC)
1 When a drive has not been identified by the SCSI
→ • Check SCSI connections.
For details, refer to Service Know-How (SKB05001).
• Do two or more SCSI devices have identical IDs?
• Is termination made at the correct position?
• Are pins of the SCSI cable connector bent?
• Are the cable and/or terminator recommended products? (Recommended cables: CC-200, CC-200-8, CC-201,
CC-201-8, recommended terminator: DRM-TM160, as of December 2004)
• Check the model number of the SCSI board. (SCSI boards whose performance with the drives has been confirmed:
Adaptec ASC-29160, ASC-39160, as of December 2004)
• Restart the system.
• If "ACARD SCSI: NULL" is displayed during identification, it is likely that the MAIN Assy is in failure.
Replace both the MAIN Assy and Traverse Mechanism Assy.
2 When a drive has not been identified by the changer
→ • Check the connections of the changer interface cable.
• Check if the wiring monitor indicator is flashing when the rear cover is open.
If it is unlit, it is likely that the WIFB Unit Relay Unit is in failure. Replace the Relay Unit.
3 When an error was generated during reading out or writing to the disc
→ • Perform a diagnosis (READ) using Diagnose5.exe. See "7.1.1 OPERATIONAL DIAGNOSIS PROGRAM."
