When your Mac is started up, SCSI Parker installs code into memory which will park selected SCSI hard disks when you select Shut Down from the Finder.
(Note: Any changes you make to your drive selections will not take effect until you restart your Mac.)
For convienence, the SCSI bus is scanned to show the ID's of all connected SCSI devices. This makes sure that you know what ID your hard disk is hooked up to. The 'Update' button re-scans the SCSI bus.
If the 'Show icon at startup' button is clicked, SCSI Parker's icon will be shown on the bottom of your screen when it is installed during startup.
If you don't want SCSI Parker to install itself, hold down the mouse button during startup. (You won't see the icon if it doesn't install itself.)
Do you need SCSI Parker?
If your hard disk comes with a special program that you have to use to park your SCSI hard disk, you probably do.
Can your hard disk use SCSI parker?
Most SCSI hard disks can be parked simply by sending them a SCSI “STOP” command. Try it; if your Mac takes longer to start up after a Shut Down than it does after a Restart, that generally means that it was properly parked.
