CD/DVD Drive not mounting

I'm not sure what happened...did a update via ubuntu update manager, and now the cd/dvd drive stopped mounting. I have searched, googled and swam through all the Ubuntu forums...and I can't figure it out. The thing worked just yesterday I just lost my job so I want to extinguish all possibilities that it is a problem with the drive before I go drop some $$$ on a new one.

Any help would be GREATLY appreciated!

here is some background:.....

My /ect/fstab

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda5
UUID=3cbd0c59-7b68-4c4c-a35b-318d75f5eb0d / ext3 relatime,errors=remount-ro 0 1
# /dev/sda6
UUID=fce1cb71-1674-4e5f-98e8-59e87ca107de none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0

Also did:
sudo lshw -C disk
  *-cdrom
       description: DVD writer
       product: DVD_RW ND-1300A
       vendor: _NEC
       physical id: 1
       bus info: scsi@1:0.0.0
       logical name: /dev/cdrom
       logical name: /dev/dvd
       logical name: /dev/scd0
       logical name: /dev/sr0
       version: 1.70
       serial: [_NEC DVD_RW ND-1300A 1.7003101600
       capabilities: removable audio cd-r cd-rw dvd dvd-r
       configuration: ansiversion=5 status=open

I've tried manually mounting the device via these codes:
sudo mount /dev/scd0 /media/cdrom0

I have also tried
sudo mount -t iso9660 /dev/scd0 /media/cdrom0

And all I get is, "no medium found" even though there is a data cd in the drive.

In addition I have tried editing the fstab line from this:
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
to this:
/dev/scd0 /media/cdrom0 auto user,noauto,exec,utf8 0 0

Still nothing....

Again, any help would be greatly appreciated! Thanks!!
