CHAPTER 12 — Troubleshooting
this will cause the drive to eject the CD. A blank or incorrectly written CD-R
disc, or a damaged, scratched, or otherwise unreadable CD will cause this
same symptom. Inserting a known good disc will correct this problem.

12.3 Apple Macintosh

Symptoms
• Invalid drive specification
• No device found
• Drive not responding
Possible Cause and Solution
SCSI Address Conflicts with the Hard Disk Drive
This usually can be corrected by selecting another SCSI address (normally
addresses 1 to 6) for your CD-ROM drive.
NOTE: The Macintosh's hard disk uses address 0 and its internal SCSI adapter
uses address 7.
Bad connection between CD-ROM drive and SCSI interface
Check cable for bent pins.
Symptom
• Computer does not respond
Possible Cause and Solution
INIT Conflicts
Remove all INITs except those absolutely needed from your System Folder and
the ones copied from the CD-ROM device driver disk. If the CD-ROM drive
functions correctly, reinstall the INITs one at a time, restarting the Macintosh
after each one, until the problem is solved.
