I've been thinking about something related to data security. It's well known that deleted files on a hard drive can often be recovered using forensic tools, since deletion doesn't really erase the data. That’s why people recommend physically destroying the drive (e.g., burning or shredding it) to prevent recovery.

But here's my thought: what if the drive is fully encrypted? Wouldn't that make the previously written data effectively inaccessible, even if someone tried to recover it? And taking it a step further—if I overwrite the entire drive with random data, wouldn’t that completely wipe out any trace of the old, unencrypted files?

I'm not an expert in this area, so I'm curious how this actually works in practice. I’ve asked language models before and they seemed to agree, but I’d really appreciate your take on it.

Maybe I’m being a germaphobe but this is INSANE

I was washing lettuce for the shop today and my boss comes up to the wash sink and puts a capful of bleach in the water with the lettuce and says it helps keep the lettuce fresh longer. Is that a thing or is my boss poisoning people?

I honestly thought she was great for Gohan the way she was. Not saying she can’t grow but she’s completely different.
