Computer doesn’t recognize your Scsi devices

SCSI devices

You can’t turn on the computer after connecting a SCSI device.

nSCSI devices must be turned on before the computer itself. Turn on the SCSI device(s) first, and then turn on the computer.

The computer doesn’t recognize your SCSI devices.

nThe devices may be off. Check to make sure that they are plugged in and turned on.

nIf the device is a disk drive, it may need to be initialized before you can use it. See the instructions that came with the device.

nThe software (driver) needed to run the device may not be installed in your System Folder. See the instructions that came with the device.

nTwo or more devices in the SCSI chain may have the same ID number. Check the ID number of each device to make sure each one has its own number between 1 and 6, and change any numbers that are not unique. (If there is a hard disk in your Duo Dock, that disk has the ID number 1.)

nWhen connecting SCSI equipment, it is important to use the right cables and the correct number and placement of cable terminators. Check the cables and terminators in the SCSI chain and make sure that all cables are firmly attached.

nA PowerBook connected to a Duo MiniDock in sleep cannot recognize an attached SCSI device. Make sure the SCSI device is turned on, and then restart the computer.

See Chapter 13 for more information about working with SCSI devices.
