I just got a Super Eagle, came with my new Sun-3/280S.  Right now the 280
is using an existing Eagle, and the 2361 is still in the box.  From the
horror stories, I plan on using the SE to store not-as-important partitions
(like Netnews  :-), for example dumping my 6 Sun source tapes onto one 
partition (thus if it craps out, I haven't lost anything irreplaceable).
Of course, I do backups every day so major lossage isn't too likely, unless
the whole damn thing crashes through the floor.

Two questions:

(1) Everyone keeps throwing `HDA' out.  Explain, please.  I can't find any
mention of an HDA or HDA revision on the sheets that came with it (in the
packet with the media defect list).

(2) How can I tell if it was manufactured late enough to hopefully be more
reliable than the previous ones?  Here's some relevant data:
	Serial # J6191	Manufacture date 11/86
	DE serial # JG6753, media defect list generated 11/25/86
	`Total Revision' A - 9; B - 8 ; C - 2.
	`P.C.B. revision levels: Logic 14F, Read Amp 19D, Servo 22D,
		I/F Basic 06B, Power Amp 07B, Display Panel 08B,
		Back Panel 09A

Like I said, I can't find any `HDA revision' mentioned anywhere.  Is it
something you can read off of the drive itself?

Any info appreciated ...
