mCheck that all cable connections are secure.

mWhen you use SCSI disk mode, the computer should display an icon with a number in it.

If the computer starts up normally, immediately press the Power key to shut down (if you can) or turn off the computer. If you don’t, you might damage your information or equipment.

mMake sure you are using the correct cable for SCSI disk mode. The HDI-30 SCSI Disk Adapter is about 10 inches long, is dark gray, and has 30 pins in the connector (no “missing” pins). Do not use the HDI-30 SCSI System Cable, which is light gray, is about 20 inches long, and has 29 pins in the connector (one “missing” pin). That cable is for connecting SCSI equipment to a Duo Dock Plus or a Duo MiniDock.

mCheck that all cable connections are secure.

mThe PowerBook’s battery may be drained. Plug in the power adapter and let the battery charge for a few minutes. Then press the Power key on the PowerBook’s keyboard to restart it, and restart the other Macintosh.

mStart up the other Macintosh with the Disk Tools disk that came with it (do not use the disk that came with your PowerBook). If the connection works, then a system software extension on the other Macintosh may be causing the problem.

When I start up using SCSI disk mode, I see a flashing question mark icon.

mMake sure you are using the correct cable for SCSI disk mode. The HDI-30 SCSI Disk Adapter is about 10 inches long, is dark gray, and has 30 pins in the connector (no “missing” pins). Do not use the longer, light gray HDI-30 SCSI System Cable.

mMake sure terminators are placed correctly in the SCSI chain. See “Connecting SCSI Devices” in Chapter 3 for more information.
