While replacing my dead hard drive a small metal piece fell on my worktable. I think it fell out of the old drive, but maybe from the mac mini itself (late 2009 model, A1283). The metal piece is silver, thickness of a dime, roughly square, and about 1/4 inch (at the most) on all sides. No holes, prongs, adhesive, connectors, etc. Just a small hunk of metal. I haven't put the mini back together yet to see what isn't (??) working. Any ideas? Thanks!
