donating is the theme of this project so here is my part.
i found your e-mail by clicking on your name.
i have sent you a program for just such things. becareful with it as it WILL whipe out every thing on the boot drive. you'll have to unzip the file and copy the contents to a floppy disk. the disk will be bootable, just folow the instructions and let it run. depending on the size of the drive, it could take several houres. i got it from a service shop a while back when i was going to sell an old hard drive. i'm not sure where it's from but it was free and works like a charm!
P.S. i hope people take this as an example and donate thier old equipment. i know most organizations will exept them.
