Ok, this is a bit crazy for me anyway. I have a Mac Mini Server running Snow. My Server HD failed but fortunately my Mac HD was being used as an image backup and I can boot from it fine and runs perfect. The bad disk was not showing in Disk Utility at all. So I bought a new one and replaced it.

 

Now Disk Utility sees it but if I try to format it or partition it, I get the message the it cannot be dismounted. I tried re-setting NVRam (Optio+CMD+P+R) but n luck.

 

I have my original Snow DVD but I have no external DVD. I have a MacBook Pro Mountain Lion.

 

How do I erase my new disk so I can copy everything back?

 

Any help is appreciate it.
