I stupidly began to erase my hard disk with zeros using disk utility on the Software Install disk. I had 40 gigabytes of data on my 60 gigabyte disk...does anyone have any idea this is going to take? its been going 30 minutes now. Is there any way i can safely stop it? there is no cancel button. I was plannin on erasing the disk anyways, but i just don't want to wait for this stupid overwrite to finish.
