Hi, I was trying to unmount an iso image I had successfully mounted. Was unable to do this. Using the 220.127.116.11 version on Vista Home Premium. I tried to do this following ways - 1. The virtual drive was J:. Right clicked on J drive, selected 'Virtual Clone Drive'. It showed the mounted image at the bottom. Then selected 'unmount' but nothing happened. I was expecting to see the mounted image to not show up after this action. 2. Also tried from the command prompt vcdmount /u. Thanks. Tapan.
