erase hard drive on eMac OS 10
I am trying to erase the hard drive of eMac OS 10.3.9. Tried Command + R keys while rebooting but disk utility wont let me erase. The erase button is not active/greyed out. Is there another way to erase hard drive completely? I dont need to reinstall because I am trying to discard eMac (15 years+ old). I do not have any of the installer CDs since I threw them out.
Mac OS X (10.3.x)
