Tweetor old printer. Remember the printers that used the paper with the holes in the sides?..The paper was perforated, so you could tear the edges with the holes off...ya just set a bundle of paper under it, and it fed up thru the printer. Remember how those printers sound when they started printing? That's how my hard-drive sounds everytime the screen loads. Started about 2 days ago.
I was thinking (old electronic typewriter), but it's those old printers that it sounds just like.
wtf???
