NEVER open the sealed portion of a hard disk unless you have the proper tools, atire and a Class 1 clean-room to work in! Whether or not it kills the drive instantly, you have certainly contaminated the internals with a large number of particles that can cause permanent damage. If you have any data on there that you care about, get it off quickly. I don't want to be the bringer of bad tidings, but that drive's days are now surely numbered.

That's the so-called "X2" line capacitor, perhaps the most common failure item on classic computer power supplies. It's getting so I clip that part out immediately before powering up a new "old" unit on the bench. Others may have varying opinions, but I generally don't bother replacing them and have not had any issues as a result. I believe they are intended to cut down on potential coupling of switching noise into the AC mains. They sure do stink when they go!
