There’s lots of article on this just google
If you want to make sure, just delete the files in question and write a program that opens
a file, writes about a 1 mb string of zeros to it , then closes it
Repeat until disk is full. Then delete the files that were created. Disk was about 20 mb
capacity, so it shouldn’t take long.

Passing on a request: anyone know of a way to erase user data off a Mac SE hard disk
that will leave the disk and Mac OS intact? The machine works and could go to a new home
but has privileged medical data on it so just deleting files isn’t sufficient — the free
space has to be overwritten. Are there any utilities available on floppy disk that could
do it? Plan B is taking a sledgehammer to the drive, but seems a waste to go right to
euthanasia if there’s another option.
