Well over a decade ago, a younger relative advised his family members to remove all hard disks from our old PC’s when we got rid of them.

Then, he told us to drill holes into the hard disks and soak them in a mix of salt water and bleach for a few days. Then throw them away.

At that time he warned us, the so called erase programs didn’t
Do the job.

I’m glad that I am not the only one who recommends bleach on platters.

Sounds like Still Thinking’s Low Level Format With Extreme Prejudice: Open the drive, remove platters and shred (requires fairly heavy duty shredder).

Well, that's one way.......

I simply took mine out of the computer I threw away then smashed it to bits with a hammer........
