Optical Drives Not Found/Not Working

Question

Hello everyone,
I'm having trouble getting my optical drives working. They are both the same make and model, and they both have power (open and close) but they aren't recognized by the system. I installed Arch a couple of weeks ago, after the init scripts/systemd change, so nothing was broken there (I'm not sure if that would even have anything to do with it.
I've done some research to see if I could find any drivers/firmware, but all of things I've found are only for Windows. The optical drives do work in Windows. I have added myself to the 'optical' group, and dmesg | grep CD gives:
[ 0.630535] ata5.00: ATAPI: TSSTcorpCD/DVDW SH-S162L, TS04, max UDMA/33
[ 0.630560] ata5.01: ATAPI: TSSTcorpCD/DVDW SH-S162L, TS08, max UDMA/33
I also recall reading here that perhaps they aren't being picked up by the kernel, but I am very unclear on how to check to see what the kernel is picking up. I'm also not sure if they have ever worked under Arch and then stopped, or whether they never worked at all. I just found out earlier today when I went to burn a CD and xfburn gave a message saying that there were no burners found.
The /dev directory has no cdrom* or sr* listings at all. lshw also shows nothing about the optical drives. Any help would be greatly appreciated.
Thanks.

I unplugged one of the drives, but it still did not show up in /dev. I checked the systemd log and it shows the folllowing:
[dochollidae@ArchLinux ~]$ sudo journalctl | grep DVD

The one labeled "TS04" isn't there anymore, but the one that is doesn't show up in devices.
I looked into writing udev rules, and I came across this thread and created a file /etc/udev/rules.d/82-cdrom.rules:
SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="cdrom cdrw dvd dvdrw", ENV{GENERATED}=1
# permissions for IDE CD devices
SUBSYSTEMS=="ide", KERNEL=="hd[a-z]", ATTR{removable}=="1", ATTRS{media}=="cdrom*", GROUP="optical"
# permissions for SCSI CD devices
SUBSYSTEMS=="scsi", KERNEL=="s[rg][0-9]*", ATTRS{type}=="5", GROUP="optical"
That didn't do the trick, but being that I have never dealt with writing udev rules before, I'm not sure if I'm going about it the right way.
