Yeah, so there's definitely something wrong. I seem to recall from another thread that you have a Plus, do the drives behave properly on that? (If you disconnect any SCSI hard drive a Plus should behave essentially identically to a 128k if you boot it with your System 2.0 floppies, does it eject the disks before rebooting?)

Ah HA!  I tried booting off the same system disk from the same drive, but attached to my Mac Plus.  It did the same thing -- no ejection of the disk, and auto-restart.  

If I boot the Mac Plus off the HD20 with System 6.0.8, when I shut it down it ejects any disk in the external drive and gives me the "It is now safe to turn off your Macintosh" prompt.

So it must just be an early system/finder thing with external drives...
