Hi all,
I used the search on this site, but couldn't quite find what I was looking for. I hate to reopen a discussion about logic boards...but I need some help.

So...here's the story. This is the second time my logic board has fried on my iBook G3 (800 mhz).
I already had Apple repair it once last year, I called and they won't do it again. So, I am going to dismantle my poor old iBook and sell the parts.
I want to know how to erase the hard drive...when you don't have a screen to view it on!

I already connected it via Firewire to another mac and retrieved all data I need, so saving anything isn't a concern. Can I hook it up via Firewire again and use the disc utility on the host computer? Or..Can I hook up my powermac's monitor to it via VGA to see what I am doing? Well, any suggestions would help...but preferably not any involving sledgehammers

They wont do it again? Weird, I thought they had agreed to repair these logic board problems on the ibooks no matter what.

Sorry, I can't help you otherwise.

Assuming another computer can see the hard disk, you can just use disk utility to erase it.

Yes, just connect it through Firewire again and launch Disk Utility as Icruise said.

Yeah...apple won't do it again...I don't have apple care and it's been over three years since I've owned the computer. They told me it would cost around $600 to repair...hmmm...no thanks.

Just connected through Firewire and ran disc utility. I chose to erase the disc, using secure erase with a 35-pass for overwriting the info. It states that this will be "highly effective" in making sure the info can't be recovered.
I know there is software out there that boasts scrubbing your HD, but is there any advantage to that over the 35-pass overwrite in disc utility?
Thanks again for suggestions!

I highly doubt it.

THIRTY-FIVE PASSES????!!!! My heavens that's a lot! U.S. Department of Defense standards for sanitizing (wiping) disks with up through Secret information call for 1) overwriting the entire disk with a character, 2) overwriting the entire disk with the (binary) compliment of the first character, and 3) overwriting the entire disk with random characters. Thirty-five passes!!! That's MORE than enough!

Trying to recover data from a DoD wiped drive is "computationally infeasible," meaning that while theoretically just slightly possible, it would take enormous resources and time to do so. Your 35 pass option will be more than adequate to protect your personal information.
