Hi all

I have noticed a strange problem with CDs.
Recently I tried to install Visual Studio 2005 and SQL Server, both installations are split to 2 CD's.
With both installations the first disk worked fine, but when I swapped the second disk in the installation continued only for few seconds before throwing "Corrupted / missing file"

I can browse the disk within the guest and even see the required file, but when I try to open it I get the same error.
Problem can be solved by creating a image (Thank you Linux for having the "cat /dev/scd0 > /home/filenamehere.iso " command) and then mounting the image in Guest. Second disks worked fine when they are mounted from ISO image.

Any ideas what could be causing this, maybe the host is somehow locking the files??
Running VirtualBox 1.6.6 on Ubuntu 8.04

You have to let the guest OS + VM know that you've ejected the disk by
ejecting the disk in the guest through the explorer right-click menu +
using the device menu to set the CD to nothing, swapping the CD and then setting it back to point to the CD device again.

I didn't try any of those tricks, I'll give it a try if this happens again.
Strange thing though that File Explorer in XP saw correct file listing on CD but could not access the files. Also the setup continued automatically from "Insert Disk 2" prompt after inserting the second disk, which tells that OS noticed disk change.
