This article describes the proper method for exiting Target Disk Mode or SCSI Disk Mode on a PowerBook computer.

Follow the steps in the Macintosh User's Guide (for your PowerBook) for connecting and disconnecting SCSI devices to avoid loss of information and damage to your equipment.

When using SCSI Disk Mode, the proper way to quit SCSI Disk Mode is to:

1. Shut Down the computer (host) your PowerBook is connected to.

2. Press the power button on the PowerBook to turn it off.

3. Turn off any other SCSI devices in the chain.

4. Disconnect the PowerBook from the SCSI adapter cable.

5. Disconnect the SCSI cables from the host Macintosh.

• If you leave the adapter cable attached to the PowerBook, the computer will behave as though it is still in SCSI disk mode when you try to restart.
• If you unmount the PowerBook's SCSI icon by dragging it to the trash it may lock up the computer and possibly damage the directory information on any mounted hard drive. The damage may only be repaired by reformatting.
