1) A posted a question a few days ago asking if APPLE hard disks had their
heads automatically parked on shut down by the system software. I received two
conflicting answers. One person said yes, System 6.0.4 and later sends a 
head parking command to the hard disk. Another said no, no such command is sent
because if it were, all hard disks would be autoparked. In my opinion these two
views are not necessarily conflicting. My original question was if APPLE hard
disks (or those formatted with Apple's HD Setup) are parked. Just because 3rd
party drives aren't parked, doesn't mean Apple's couldn't be.

Can anyone from Apple confirm/deny my suspicions?

2) SCSI termination: There has been a lot of talk lately about internal vs.
external termination for external hard disks (most notably SyQuests). My
current set up is a Mac II w/ 40 meg INTERNAL HD and a LW II SC (properly
termianted of course!).

Now if I wanted to add an external SyQuest, does it matter if it is internally
or externally terminated? My IISC is externally terminted so if the SyQuest
is internally terminated, can I just make it the end of my SCSI chain and
take the terminator off of the IISC? AND if I can do that, will things still
work properly, i.e. can I use my printer without having to turn on my SyQuest
and vice versa?

Please respond by email or follow-up...I'll summarize if requested..
