There have been a few postings on the net about making the optical disks
a user mountable data drive.  I need to do the same sort of thing but
I've been stymmied.  I have had to do a few things that I didn't like 
security wise, but that's not my major concern.  The following is what
I've done...

add a group 'optical' to let specific people use the disk
chgrp optical /dev/*od* /etc/mnt /etc/disk
chmod 664 /dev/*od*   (This will let optical users write data to the OD.
chmod 4750 /etc/mnt /etc/disk

This let's me access the optical with the disk command.  I can now eject
and init ANY drive on our cube (hard drive included)

The problem is that when I try to mount the optical to anywhere (even as
root) I always get (after the disk spinup) device busy.  

Has anyone gotten beyond this point?  I need to 'hot' mount opticals
after booting.


Also, when we got our cube, we had a problem with voice mail and
stealth.  Whenever you played back voice mail or contacted the tower in
stealth, the voice was playing back at a low sample rate (it sounded
about 2-3 octaves lower then the original).  
We fixed this by recompiling the soundtest app in the Example directory
and then sfrecording a sound and playing it back with soundtest.
for some reason this seemed to clear some bit in the DSP and since then
the voice mail plays back at a normal level now. 

Does anyone know what caused this and if there's a better way to clear
the DSP???

Thanks,
Tom Leach
