what I suggest you do is take out the HDD and smash it with a hammer until it's in microscopic bits.
Oh wait. Don't do that just yet. Use Clonezilla to copy your data from HDD to SSD.
THEN you can smash the HDD with a hammer.
Wait. Don't do that either. You can actually use it for backups. Imagine. Since it's spinning rust, it will not go bad like an SSD which, if disconnected for a number of years, will lose its charge.
Old HDD make perfect media for backups. You can use that USB based gizmo where it plugs it. Both 3.5" and 2.5".
