I have reason to believe that the DVD drive is actually at /dev/scd0.
Would I risk doing harm by changing hdc=noprobe to scd0=noprobe or
sr0=noprobe?

Also, I tried verifying the location of the DVD drive in /etc/fstab,
but it's not a conventional fstab like I'm used to with the drive
letters and such. It's what is called LVM, no?
