Hello, I am trying to format a clickfree external hard drive, but disk utility cannot do it. I even tried one partition, but it doesn't work either. It was formerly used on Vista or XP (unsure). It includes a virtual cdrom partition that is about 300MB. No matter what I do (format or partition), I cannot get this drive clean. I want to make it an external drive for time machine backups. Is there any way I can get rid of this virtual cdrom, and actually wipe the drive clean, so it will work 100% on a Mac (without this annoying error message that the virtual cdrom drive cannot be read on a Mac - it asks whether I want to ignore or eject). The website is bare with facts/help about this. It says that OS X is supported, but I cannot format the damn drive. Here is a screenshot. I just want to format the entire drive and have one partition (250GB drive) to use for backups: http://dl.dropbox.com/u/8494936/Screen shot 2010-12-26 at 8.26.40 PM.png Are there any other tools that will do this job, since Disk Utility cannot? Thanks!
