i have a dell dimension 4550 WINXP PRO w/ a single DVD-RW tray.
now when i put a CD that someone has burned for me, it reads it as a blank CD.
I had similar problem. I put in a good CDRom, anything, burnt or not, and even though Windows seems to know there is a CD there, it shows no files when I select it from "My Computer".
So I right-clicked in the Window where the files should have showed up. Then I selected Properties, selected "Hardware" tab, highlighted my CDRom drive, clicked on Properties again, then "Volumes" tab, then I clicked "Populate". The window suddenly fills with info about the CD and I hear it revving up in the CDRom drive. I go back to "My Computer" and click on the CD (drive D) and there are all the files!
So I am going go to pile on with my own question: Why did my Windows XP Home forget how to auto-mount CDs??? For surely, I think I just "forced it" manually.
