Alright, I bought a new hard drive this last summer (Western Digital 160gb, if it makes any difference), and I use that as the drive to store mp3 files and such, and on two occasions, one a couple months ago, one about 20 minutes ago, I noticed that a number of my music files would seemingly disappear. When I'd right click on the drive and hit "properties," the number of files that should be there are there, but as soon as I open a folder and start browsing, they wouldn't be there. Any ideas/advice?
