Hello:  if anyone could assist me please let me know.  I am running Logic Pro 8 on a Mac G4 (yes, really....with leopard OS)  I have leopard and logic 8 installed on the main system drive.  In addition I bought a 7200 RPM 750 GB hard drive to record all of my files to.  I have no problem recording, everything seems to track just fine.  When I go to open the files in logic, I get errors, the waveforms do not load, and nothing plays.  If I record to my system disk, everything is ok.  The system records and plays back just fine.   The problem there is I DON'T want to record to the system disk!
Based on that, do you know of a misconfiguration of some sort I have?  If you need more information please let me know.
P.S. I can save and open any other file to this drive.  For example I can use text edit and save a document to the 2nd drive.  And then reopen it just fine.
