I'm trying  to do the same thing.  More or less, getting the GS to read a
Mac HD.  I have a Quantum 340LPS and the Apple HS card.

I also have Silverlining (v 5.5.3) and would advise you to keep it away from
your HD.  It uses a proprietory partitioning scheme that the GS cannot read.
This has to do with the resizing function (w/o losing data) of Silverlining.

Does this mean that your GS read the last HFS (42meg) partition?  I have
5 partitions (40/32/100/100/65) formatted with HFS and my GS doesn't read any
of them.  Did you map out each partition on your RamFast or just the drive? 
I had the same problem.  I'm going to try using the Apple HD Tools that came
with System 7 and see if my GS can read the standard HFS partitions.

Hopefully in this open forum of GS gurus something will come of all this.
I'm getting out my copy of the FAQ this very minute.
