Apple PowerBook (Duo, 2300 Series) - Manual (Page 56)

12 Turn on the other SCSI devices in the chain, if any.
13 Turn on the other computer.
The PowerBook appears as a hard disk icon on the desktop of the computer
you connected it to. You can now transfer and use files as if the PowerBook
were an external hard disk.
WARNING Always disconnect your minidock from the adapter cable
when you are not using it as a hard disk. Your PowerBook will not work
correctly if the adapter cable remains attached.
WARNING If you do not see the SCSI icon, and the computer starts
normally or displays an error message, choose Shut Down (if you can)
and then immediately disconnect your computer from the SCSI chain.
(If you can’t choose Shut Down, you should disconnect the cable
anyway, or you may lose information.) Then go back and repeat steps 6
through 10, making sure to use the proper cables.
Password protection must be turned off in the Password Security control
panel while using your PowerBook in SCSI disk mode. Turn password
protection off if you experience problems. See “How do I turn password
security on and off?” in the “Setting Options” topic area of Macintosh
Guide, available in the Guide (h) menu.
