sata optical drive-unable to mount. after upgrade

[Kris]

hi,

I have been a linux user for sometime now but have never changed any
hardware before.

I previously had a IDE optical drive. I now have a sata optical drive but
unable to mount it (it works fine with other live cds).


This is my /etc/fstab

--snip--

/dev/cdrom2              /mnt/disc              iso9660   rw,defaults      0
0

--snip--


I figured that the drive points to sr0


$ll /dev

--snip--

lrwxrwxrwx  1 root root          3 2008-03-04 16:57 cdrom2 -> sr0

--snip--


I did this

#sdparm --all /dev/sr0

/dev/sr0: HL-DT-ST  DVDRAM GH20NS10   EL00  [cd/dvd]
mode sense command failed, unit attention


unable to mount the drive the usual way using the mount command


this happens after a disc change.

$dmesg

--snip--
