Help - destroyed partition map - on my real (OSX) drive ...

[Grant Lenahan]

Well folks, I need advice - asap.
I tried installing YDL 3.0 today.  I have two drives, each with two 
partitions.  Drive #1 contains OS9 and OSX - each on its own 
partition.  Drive #2 has a backup partition, and one waiting for YDL 
(actually, it already had 2.3 running).

Somewhere along the line there was an installation error,and when I 
went back i to erase partitions and create new ones, somehow Drive #1 
was damaged.  but wait, there's more.

If I boot into OS9, all the partitions show up fine.  The OS9 
partition boots.  The OSX partition shows all the files - intact.

BUT!, if I boot into Linux or OSX, Drive 1 vanishes.  If I run the 
YDL installer, it tells me that Drive #1's partition map has been 
damaged/lost and the drive must be fully formatted.  No. I have not 
done that yet.

Worse comes to worse, I have a drive image of my OSX partition and 
can erase it, but it will be a tedious process.  I'm also gun-shy 
about what might have happened.  For the record, I've successfully 
installed and deleted YDL partitions many times on other machines, 
where it didn't really matter anyway.

Any Genius' who know what went wrong,and how to fix it (short of 
wiping the drive and praying that carbon copy cloner will come to my 
rescue)?
