 Yet the icon is on my desktop, and when I double click it, Nautilus open
 it.

 So what's controlling the device?

 It just occurred to me to do:
 r...@edwin:~# ps -ef | grep scd0
 root  6521  6477  0 Jun14 ?00:01:00 hald-addon-storage:
 polling /dev/scd0 (every 2 sec)
 root 15023 14855  0 17:34 pts/500:00:00 grep scd0
 r...@edwin:~#

 Any idea what hald-addon-storage is?


That's the hardware abstraction layer device add on storage daemon.

It's safe to kill, BTW.

# kill -9 6521

remove device - enter device

# dmesg

# mount /dev/scd0 /mnt/CDROM (or whatever the directory is)
# mount

If you want to have it mount automagically, add it to /etc/fstab

Start back the hald-add-on-storage from the /etc/init.d/ directory.

  So, you will umount it
 
  #umount /dev/scd0
  or
  # umount /mnt/CDROM  (or wherever she is mounted)
 
  then
 
  # mount /dev/scd0 /mnt/CDROM

 Kind of a screwy command if you ask me.
 
 FWIW, does anyone know of a gnome way to turn device polling off/on?

That helps, but still no dice.

Visduh (running under VMware Player 2.5.2) accesses a (commercial) data 
disk flawlessly, regardless of hal polling (on the Ubuntu host) being 
enabled or not. I suppose that's because Ubuntu doesn't know what to do 
with it, so it does nothing with/to it.

I'm unable to access a (commercial) audio CD though. I tried stopping 
hal on the Ubuntu host, and that made things worse, as Visduh would 
hang. With hal running and polling disabled, Visduh acts as though 
there's nothing in the drive.

/var/log/messages gives this hint (repeatedly) when trying to recognize

So, you will umount it

then

 I have a Ubuntu 8.04 host, running a Visduh guest using vmware player

 I'm trying to use the Windoze media player to rip a CD, accessing the
 CDrom directly. The Vista VM is connected to the /dev/scd0 device, but
 when I insert the CD, Ubuntu delightfully and magically puts the Audio
 CD icon on my desktop, and launches the Sound Juicer. Ubuntu takes
 possession of the CD device, and Visduh waits for access.
 
 I can't seem to figure out how to get Ubuntu to release the device so
 that VMware/Visduh can access it. Once I eject the disc from Ubuntu,
 Visduh stops waiting for the device. When Ubuntu has access to the CDrom
 device, there's no entry in /etc/mtab, so the device isn't mounted by
 conventional means.
 
 Can someone fill me in on where to look to find out what Ubuntu's using
 to access the CDrom, and how I can get it to release (umount?) the da*m
 thing without ejecting it?
 
 TIA.

To disable:
# hal-disable-polling --device /dev/scd0
This allows the VM guest to access/control the device directly.

To re-enable:
# hal-disable-polling --device /dev/scd0 --enable-polling

Kind of a screwy command if you ask me.

FWIW, does anyone know of a gnome way to turn device polling off/on?
