Hi I have recently bought a new MAcmini and I love it. I had been using a simpletech 400GB drive on windows and I moved it to the MAcmini. Unfortunately it was formatted in NTFS. I am using Disk utility to format it to DOS. I went to erase and chose the volume format to be MS-DOS and then clicked on erase. The disk utility has been active for more than 3 hours and I can not stop it or kill the application! HELP!!!!!
