MyghKaR5b Posted March 17, 2007 Share Posted March 17, 2007 Hi all. If I wanted to use Terminal.app to format my hard drive prior to installing OS X what command would I use. I plan on using the entire hard drive for OS X only. Thank you -tussey Link to comment Share on other sites More sharing options...
erbic Posted March 17, 2007 Share Posted March 17, 2007 Run Terminal from the install DVD. diskutil list In the list produced, find the identifier of the drive you want to erase. It'll be something like disk0, disk1, etc. Then... diskutil eraseDisk HFS+ "Macintosh HD" disk0 Replace 'disk0' with the disk identifier you figured out earlier, and you can replace "Macintosh HD" with whatever you want your volume to be named. If it has spaces, you MUST keep it in quotes. Otherwise the command will error out. If you're not running it from the install DVD... run it from the install DVD. You can't erase your OS X disk from within OS X. Link to comment Share on other sites More sharing options...
MyghKaR5b Posted March 17, 2007 Author Share Posted March 17, 2007 I tried this and it still didn't work. It reformats perfectly and OS X installs fine but then my motherboard (intel bad axe 2) never sees the HD as a valid bootup option. Any other ideas? Thanks.
