I burned a CD months ago on another box. When I put it in my laptop drive, it doesn't show that any files are there, but the CD picture (properties) shows that it is completely filled. Hard to tell by physically looking at it if anything was actually written to it, but I'm pretty sure there was. Thanks!

UPDATE: Weird, but I opened it in Roxio and it shows the ZIP files on the CD, but when I try to append 1 file to the CD, it errors out. I thought that might be a way to get Windows to recognize it, but no.
