    Hi All -- I'm new to this forum so forgive me any blunders.

    I have an old Power 7500/100 Mac PC, which I would like to donate, but I'd like to completely erase the hard drive of all myn personal material first. Anybody know the best way to do it?

    I'm not sure what OS you are running, but I thought that the later ones (8.6/9) would let you erase the harddrive when you did an install. When you boot off the disk, search around in the installer and disk utility. Sorry I can't help more, it's been awhile since I did a system 9 install.

    I can't quite recall the OS 9 Disk Utility either, but you'll have to startup off the OS 8/9 CD first (restart and just after hear the bong, hold down the C key).

    If you see a background made up of CD's, then you're booting off the CD.

    There is a copy of Disk Utility on the CD, go ahead and open that. I think there are options in there to overwrite all data on the disk with zeroes. I think it's a checkbox labelled as Zero all data or something, I think you hit the options button. Just a simple reformat won't work since all the old data will remain intact until it's overwritten. If you overwrite it with zeroes, it will be harder to recover.
