I bought a new Hitachi 1tb bare drive and have been trying to format it through Disk Utility. I have it connected to my iMac system using a Newertech USB 2.0 drive connector. The new drive appears in Disk Utility, and when I go through the "Erase" tab and set if up as Journaled - the system seems to go into formatting mode for about ten minutes and then I get an error and I have to Force Quit the Disk Utility. Any suggestions? Thanks!
