I've got a problem that's going on as I type this and would like advice on how to proceed. I am trying to format a brand new 120 GB hard drive via an external USB 2.0 enclosure. About 25 minutes ago, I selected the "erase" option and slected the Mac OS Extended (Journal) Volume format. For the last 25 minutes, disk utility has been saying that it's creating a partition map. It's doing nothing. I have reason to believe my enclosure may be faulty. (I had a similar problem on an old hard disk and thought that the problem was with the disk; now I know.) I need to know: How do I disconnect/eject the hard disk without damaging it? The eject option in Disk Utility is grayed out. If I attempt to quit Disk Utility I get a warning telling me I could leave my disk inoperable. What's the safest way to go about this? Thanks for the advice!
