I chose to use a non-journaled HFS+ file system so I could share the drive between Mac and Linux systems without the file size limitation that FAT2 imposes.  This was working pretty well for a while. The idea was to use my Mac laptop in the field, but still be able to open the Ardour sessions with my Linux desktop.  Now that I have Ubuntu Studio on the laptop as well, it's kind of moot.  Maybe it's best to back up the files, reformat the disk ext3, and put the files back. (Recall that the disk is readable, just not writable).  OTOH I see value in learning about interoperability betwen Linux and Mac OS, since I might want to collaborate with a Mac user. --Paul </div></div> </div>
