I'm trying to reformat the hard drive on an iMac G5 prior to selling it. I've booted the Mac from the installation DVD that came with it, opened Disk Utility, and told it to erase the drive using both security options for zeroing out and rewriting the data. However, Disk Utility seems to be hanging: I let it run for over 12 hours and it didn't finish; I needed to unplug the Mac and restart it (the program wouldn't even let me force-quit it.)
I started the process again, but it still seems to be going extraordinarily slowly. Is there something wrong with this, or does it just plain take a long time? I'm not hearing the hard disc spinning; it sounds like it's hung again.
