David,

I think this behaviour is normal, because MacOS doesn't read "open" CD-Rs
unless you use the Direct CD software and the CDrecorder as drive directly
connected to the Mac...  on the Adaptec WWW page there is more detailed
information about this...

http://www.adaptec.com/tools/compatibility/dcdread.html

If I understand it right, you might be able to access the disk over the
network if you have it inside the CDR writer, but not in a conventional CD
drive... however I have not tested this, and you might have to install the
Direct CD on the networked machine as well... I doubt that you can read the
disk in the PowerMac if it's in a CDR writer which is itself connected to a
PC... maybe the other way round it works ???

I'd be curious if anybody comes up with some realworld results, because we
might have the same problems here in the future...

cheers, Matthias
