Hello SCSIers!

I come to you begging... on my knees... crawling... for HELP!

I will try to describe to you as clearly as possible the problem I
am facing...

Technical stuff:

	Hard drive:	Seagate ST1280N
	Machine:	Macintosh SE/30

	HD condition:			Said to be working (I hope).
	Mac's SCSI interface:	Working!


I have presently a Seagate ST1280N hard drive. All I can say about
the drive is that it was working before landing in my hands. About
the Macintosh... gee... it's interface is working perfectly. I
already have a Quantum 210 in it. (Please... do not complain about
the Mac's SCSI interface or the quality of drives! That's not the
purpose of this message!

Now... let's start talking about serious stuff here... at least I
think it's serious!

I took out the Quantum and hooked the Seagate INSIDE the Mac. Power
cord is fine and working. SCSI cable fine and working. Remember
that there was a Quantum in it before!

I switch the power on and I wait! The Mac starts... the hard drive's
motor starts to spin. (Every time I do this I hope it will work!).
I hear a loud "click". So I guess the heads are not parked anymore!
The heads go a little crazy for a second or two. I guess it's doing
some initializing... as with the Quantum.

The LED flashes once and then nothing! I have to push on the
diskette and wait for the desktop. No dialog telling me about the
presence of the hard drive nor telling me that the hard drive is
not formatted. NOTHING! ZIPPO! I say that because it happened to me
before that when the hard drive is messed up, once the OS is
loaded, it says that the drive needs to be initialized.

So in despair, I load SilverLining (version 5.2). Then I get this
message: "SCSI bus not responding. Check that devices are connected
and powered up". BIG DEAL! They are connected and powered up dummy!
I presume that it's not the Mac's SCSI bus but instead the drive's.

I then press CANCEL and go to the Diagnose menu (command D). I try
to do a reset... but then again it says that the bus is not
responding... But... there is a little glimpse of hope... Everytime
I press the reset button, the drive's led goes on and I hear the
heads moving... So I say: What the heck... let's try and format it
anyway! I did try too so... but the darn Mac bombs everytime I try
to format the drive... either in System 7.0.1 or in System 6.0.8.

So I started to play with the hard drive's jumpers. I have tried
the parity jumper (enabled and disabled), the the bus jumpers
(drive supplyes, supplied by computer and finally a mix of the 2).
Then I have tried the SCSI address jumpers: The 3 jumpers
combination give a total of 7 (4 - 2 - 1). Nothing! Nothing at all!

So i nfrustration, I almost took the drive out and throw it accross
the street!

So here I am SCSIers... left alone on dark path of SCSI land...
Please... help me! I beg of you! I have unfortunately no idea AT
ALL on the specifications of the drive (# of head, capacity once
formatted, etc).

I thank you all very much in advance... even you aren't able to
help me!
