Yes, the problem is that the disk never mounts, so I never get an opportunity to try disk utility on it.
This is a combo 2.0/3.0 USB unit. That might be a clue to its quirkiness? The problem with that is, it worked in the past. It was my Leopard boot disk, created on a Powerbook G4 PPC, running Leopard. I used this disk as a boot-up drive to run 32-bit applications under 10.5.8 (Leopard) from my Macbook.
Then I discovered that the reason I hadn’t been able to properly save documents under Adobe CS2 was that the My Passport had been formatted as a “Mac OS Extended (Case Sensitive, Journaled). I had to reformat Mac OS Extended (Journaled)” (HFS+) in order to write Adobe CS2 documents.
So, being on my Macbook, running Lion (10.7.5) at the time, I reformatted the disk there. That went fine, but when I tried to mount on the Powerbook G4, the mount never completed: just an endlessly repetitive “whirrrrrrr-click, whirrrrrr-click.”
Thanks for looking into this!
