Apple Logic Pro /LogicExpress Discussion

Hi,

I just bought Logic, and I just joined the group. A quick search of  
the archives turned up some replies to my questions, but I still need  
a bit more help. I don't quite understand the whole installation  
procedure for Logic.

I put the main applications on my system drive, as well as the analog  
and digital "extreme" synths. I put several other things on my system  
drive also, but I definitely can't remember all the file names.  
Basically, I unchecked whatever I knew would not fit (I had about 21  
Gigs left on my system drive when I began installation).

What I did not install (among other things) was the Jam Packs, since  
they are way too big to put on my system drive at present. I do have  
an external (partitioned) HD with 210 GB allocated to music. I  
assumed I could put the Jam Packs and any other sound libraries on  
the external drive. But the main install disc will not let me put the  
Jam Packs (or any other content from the first dvd) on an external  
drive. When I tried to put any of the disc 1 content on my external  
drive, I got red "!" errors, stating that the content could not be  
installed on that drive, but instead "must be installed on the  
running system."

So, I see that there are 6 other discs here--3 Audio Content install  
discs and 3 Jam Pack content discs. My questions:

1. What's the story with the Jam Pack content on the main install  
disc?  Is the content the same as on the separate discs? Since I  
could not install the Jam Packs onto my system drive from the main  
install disc, should I just install them on my external drive using  
the other discs?

2. Are the 3 Audio Content discs *only* for use with Soundtrack Pro  
(which I doubt I will use...at least not right away)? Or is there  
audio content here that I might want to use with Logic?

Any help getting this sorted out would be much appreciated. I don't  
want to overlook any essential content that I should install right away.

Powerbook G4, 1.67 MHz, 1.5 GB RAM, 80 GB HD (only about 13 Gigs free  
now)
I'd call myself a serious hobbyist, definitely not a pro. I'm  
completely new to Logic. If anyone needs any other info. about my  
setup, additional applications I'll be using with Logic, or anything  
else, I'll be happy to provide it if it will help sort out any of the  
above questions.

Thanks,

Jeff
