I have an ext passport hard drive, I put it in a pc to convert an omf to ptf protools, then I put it in a mac to access and work in a protools session and it can see all the files when I open it in the program, but it can't read any files when I open the passoport hard drive directly - it's coming up with 3 folders - Recycled, Stuff(my file name) and System Volume Information containing a restore folder with three more folders. What can I do so the hard drive reads the files?
