The Logic Off Topic list

Any help or thoughts would be appreciated.  Here is the problem.

On Monday I acquired Panther for an upgrade.  Figured I'd get this 
out of the way then go from Logic 5.5.1 to Logic Pro when it is 
released.  Since I am a "switcher" (about 1 year ago) I wasn't 
expecting what happened - which was Panther kepts freezing around 
13% when writing System Base 1 files.  I went to the Apple store 
(Newport Beach) and we started brainstorming.  We took out memory 
cards (I've got 2 gigs total).  Same thing.  we tried a different 
Panther disk (same thing /problem).  we pulled out the Delta 1010 
card (same thing /problem).  

Since I bought my machine through my favorite music store - who got 
it from mac mall - I've come to learn that my memory cards and SCSI 
hard drives are not "apple made" and therefore my warranty does not 
apply (from Mac).  The techs called me tonight and said "we put in 
an IDE hard drive and got Panther installed no problem. We think 
your SCSI drive or controller is the issue (that is what I suspected 
after all my other test)".  We'll run some 12 hour hardware test and 
call you in the morning and let you know the next step.  Now my 
question for the group - do any of you have SCSI hard drives and 
cards in your machine and did you exeperience any trouble upgrading 
to Panther?  I don't want to "clean install" because it will take 
another week of getting Logic and the Delta 1010 and Core Midi/Audio 
working.  

Any advise or "war stories" appreciated.  Post here if it is helpful 
to the group or privately at Antcinq@....

Thanks
