What do I do to wipe them clean?
If you wish to recycle the computers by giving them away, and if you can find appropriate system CDs or a Disk Tools floppy, you could use Drive Setup. Start the computer from a system disc or from a Disk Tools floppy. Locate the Drive Setup utility. Look for a Functions menu. Choose Initialization Options and then check "Zero all data".
If necessary, Disk Tools PPC (here) can be downloaded. Disk Copy 6.3.3 (the Make a Floppy command) is used to create a bootable floppy.
Do I just put everything that's personal into the trash and empty it?
No, that is not sufficient. Only the directory entries are deleted this way. As you already indicated, the contents can be easily retrieved. One should always overwrite the "emptied" space. If a dedicated utility for this (such as Wipe Info from Norton Utilities, or the freeware program Burn 2.5) is not available, one could duplicate a single large (not personal) file until the hard disk is full.
It depends on what you mean by recycle. You state " I suspect that anyone getting these computers would not go to all that work." If you want someone to benefit from the use of the computers, take the time to find the restore CDs that came with the computers. Start up from the CD by holding down the C key when turning on the power. Soon you should hear the CD-ROM drive spin up or ratchet up, as it sometimes sounds,then let go of the D key.
Open up drive setup as Jan mentioned and select 'erase drive.' Find the option to zero out data and then select erase drive.
If you just want the parts to stay out of a land fill, go to Home Depot, buy some small torx screw drivers. Take the drive apart for the education and use the drive platters as wind chimes. The data will forever be blowing in the wind.
Thanks Jan and Jim for the advice.
I have since found a copy of OS 9 and used that to initialize the Power Macintosh G3 as I couldn't find the originals for this machine. But it worked just great and I followed the steps you had outlined and selected "Zero all data".
Now for my Performa 6300, I have found the original install cd for this machine but was thinking of using the OS 9 cd again and taking it thought the same steps. I understand that this machine's maximum OS is OS 9.1 so the OS 9 should be okay. I will let you know how that goes.
I, too, have the original Performa 6300CD installation disks, but I could not find any documentation that assured that the formatting or erase operations zeroed out the data or only the directories. Rather than take a chance, I removed the disk, after finding directions for removing the disk at dennvoiles.free.fr/sub/temp/MacG/performa62006300.pdf . I will recycle the rest.
For future reference, if you boot to the System/Install CD, the Hard Drive is completely available and can be fully zeroed with Drive Setup using an initialize with Write Zeroes option. Your data will be completely overwritten with zeroes. Only those willing to disassemble it and examine it in a clean-room with special equipment would be able to recover any of your data.
deleting the data with the Finder just removes the Directory entries -- the data blocks are not erased.
Thanks for the information, but I am almost glad that I did not have it before I removed the disk - especially considering our plan to recycle it rather than donate it. We have not used the Performa for over 5 years, and I think it took less time (about ten minutes) to remove the disk than it would have to start it up again. The only tools required were a flat screwdriver and a Phillips screwdriver.
