I bought the 500 gb mybook from western digital. I have a 1.33ghz pb g4. I wanted to transfer a fairly large ammount of data from my pc (running ubuntu). The only problem is that when formatted for MacOS ubuntu won't write to the drive. So I partitioned 100 gb as fat 32 and transfered the data from my pc to that partition. Now... When I hook up the external hard drive to my powerbook I only can mount the partition formatted for mac OS (makes sense..). Is there any way that you guys can think of that I can have all the data on the external hard drive accessible on my powerbook? I'm talking along the lines of being able to mount the fat32 partition as read only and having a macOS partition that is read/write. Any ideas? I'm not looking forward to putting all of my data on DL dvd's....that would take forever.
