Sorry, I don't know what hsf+ is? I am a graphic designer that is trying to move files which I probably should have moved along time ago. This passport drive is only going to be used for MAC computers. There are other options to choose from :
Mac OS extended (journaled)
Mac OS extended
Mac OS extended (case-sensitive, journaled)
Mac OS extended (case sensitive)
I have formatted as MS-DOS (FAT) and the drive still can't be seen on the PowerMac G4 which is odd since the computer can read and copy files using my little travel drive. It would take hours to transfer files using the travel drive.
Unfortunately I can't install OS 10.6.8 on the G4 because it won't be able to handle it. At this point do you think it is a lost cause and I should take the computer to Apple to see if they can get the info off the computer? Or do you think one of the options listed above might work?
