I was downloading a hard to find song and sure enough....wham!!!!! It re-wrote my desktop immediately so that all buttons leading to my hard-drive, some files and my programs manager, disappeared. I tried every trick I knew and finally yanked the hard-drive and chucked it in the garbage. The plus side is I have a new, cleaner, faster and larger hard-drive and a somewhat fresh start on things. Two days of pure computer hell though. Not too far from giving it to one of my kids and weening myself off of some of this technology.
