Now what should I do with the bad hard drive?

Wear it around my neck as an amulet to ward off evil computer spirits.

Put it in a jar of mineral oil and take it on tour like Captain Love did with the head of Joaquin Murrieta.

Enchant it into a voodoo doll to inflict pain and suffering on any other computers that misbehave.

Disassemble it for parts like, you know, magnets. You can do magic tricks with magnets.

Grind it into a powder, dissolve it, and drink it, so that I can absorb it's power.

SMASH IT WITH A HAMMER.
