I've been physically destroying several old hard drives and prepping a pile of old electronics for recycling. The HDD in this old acer palmtop was too hard to get out. I couldn't even figure it out. So I found this very old software to supposedly wipe it. It's fine, I only ever used this thing to tinker with Arduino anyway.
@Nonya_Bidniss old HDDs are actually securely erasable, unlike SSDs where it's rather a "Trust me Bro!" kinda thing.

@kkarhan @Nonya_Bidniss

Old HDDs are not be securely erased unless you do it like US navy erased them.
Dip them in acid 🍵
Some drive tracks can be read on the "outside".
By state actors mainly.

However, both HDD and SSDs can be permanently erased in a microwave 😁
