After the latest Win 7 updates on three of my computers, the CD drive does not read blank CDs. It gives an error message "Windows cannot read the disk in drive E:\"
etc, format the disk etc.
I was always able to put a blank CD in the drive and see that it was blank or could copy files to drive. Now, it only gives me this message. I tried several different blank CDs. They work fine in my older XP computer.
Try restore to date before updates applied, or uninstall the updates.
In the future, choose custom install, as there may be updates you don't want to install !
