Anti-vibration HDD screws/mounts?

Does anyone happen to know where I could pick up some HDD screws that come with those little rubber washers (picture)?
The hard drive I've got installed in my server rack—it doesn't have those rubber mounts, you see—and it’s making this... I don't know, this tiny, barely audible but honestly just maddening vibration sound inside the chassis 🙂.

eBay?

If you’ve really checked every single store around town, maybe give Chipotles a shot? They’re always pulling those kinds of stunts 🙂

So, I finally went ahead and rigged something up using some longer screws and those rubber bands you find around the house. And honestly? It actually worked. The noise is totally gone now. 🙂
