The easiest method is to have an external drive, boot from it and then wipe the internal drive. Also, if you have an install CD for each machine, you can boot from it, erase the drives (select the option to write zeros over the top of any data on the drive, then install a clean system. This allows someone else use of your computers.
List a city near you and maybe we can find a user group to help you out.
First time forum user here: I was just given an older G3 - I think from about 1999. These used to be called really powerful machines....but I am a PC user since 1986... a MacBook user for only a year....and find the Apple OS confusing. Still, I hope this G3 can be put to use. Can you tell me what the most recent OS is, that would work on this machine? I guess it does NOT have the Intel chip so using Windows is out of the question, but even the latest Apple OS's might not work? Some guidance would be greatly appreciated to put this warhorse to good use. Thanks.

Eric, I have an old thread titled "Tiger in the beige G3 and a Few Observations on it's Behavior" SOMEWHERE on this forum (it's been moved) If you start with that, you can get an idea of what you can do.
Tiger OSX 10.4 is the last OS you can run, and my living room box / music server in a table is daily running the stereo and used for watching DVD's.
You need to get your hands on a spare Sonnet G4 ZIF card - I might be able to dig one out for you. Let me e-mail you directly later tonight. (dinner at in-laws commands my attention now) I have a lot of bits and bobs that need to find a good home and you can do quite a bit on those older systems.
It would also be a good idea to post your question in a new topic rather than add it to this one which covers a different question. If you put it in its own topic with a subject then other users who may be able to answer it will notice it, especially if they aren't following this hard drive erase thread.
