Mounting a multisession CD does not show the correct contents

[xanith]

I added a few files to a non-rewritable cd, then added newer versions of some of the files. When the cd was mounted (Windows 2000 VM-SP4 with additions installed, WindowsXP SP2 host), it only accessed the original versions.

Verified.

Well, I had the same problem on "Windows 2000 Server SP4" Host and openSUSE 10.2 guest.

I mounted a multi-session CD-R, so Windows host saw both sessions, while the guest saw only first one.

Known issue in the fully emulated virtual CDROM drive case. Switching the CDROM drive emulation mode to passthrough (see manual section 5.1.3, CD/DVD-ROM and floppy settings) works around this problem. As an additional advantage you can then use the full capabilities of your host CD/DVD drive, including CD/DVD writing. That setting is preserved if you switch back and forth between host CD and image mode, by the way. So no need to change it every time you mount something different.

A fix for the fully emulated virtual CDROM drive is not that difficult. Would be an ideal thing for someone from the community: it would be a relatively small change (so no need to understand everything). And additionally it would be pretty easy to provide the same fix for QEMU, which currently has the same restriction (but does not provide any workaround). So whoever wants to do this could improve two free software projects with little effort.

Please reopen if still relevant with a recent VirtualBox release.
