DVD drive not working or showing up in explorer. Help!

[PRG]

I bought a M1530 on the cheap a few months and installed Win 7 x64 with a lot of research primarily from here. Everything worked perfect. The drive is a Teac DVW28SLC. It's a slot load and the only eject button is with volume and DVD controls above the keyboard. I needed to burn something to DVD. I decided to try Imgburn for the software. Installed it, popped a fresh DVD-R in. DVD drive recognized the blank. I usually reboot a computer before burning, realized I didn't so I rebooted. Now, the drive no longer works.

After the reboot:
-Drive is visible to bios.
-Drive cycles on boot up, checking for a disc.
-Drive is not visible in explorer
-Drive is not visible to diskmgmt.msc
-Drive is visible, not disabled and properly installed in the device manager.
-Card reader also seems to not be visible either but is showing up in device manager.
-Disc will not eject from keyboard button.

Things I've tried to fix it:
-Several reboots.
-Uninstall Imgburn.
-Uninstall Daemon Tools Lite.
-Uninstall Drive in Device Manager, then reboot.
-Uninstall Drive and ATA controllers then reboot.
-Delete upper and lower filers at HKLM\SYSTEM\CurrentCOntrol Set\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}, no entries were present.
-Reinstall chipset drivers, though I don't think Intel installer changed or installed anything.
-Fixit does not work.

Anyways, anyone got any ideas? Am I incorrect in diagnosing this as a operating system problem? I need my DVD drive back. Help!

I'd kinda stay clear of Daemon Tools, as it can be problematic on some systems.
Have you tried using a different SATA port?

Try this: Your CD or DVD drive can't read or write media

Laptop.

@whs:

Fixit does not work

Specifically it is missing lts.dll

SFC shows no integrity violations.

Are you able to do a System Restore?

Well, it's seems there was some human error and a different problem. I didn't have the blank disc in there after all, hence why it wouldn't eject, oops. The problem is instead explorer isn't showing empty removable drives irregardless of how the option is set in file and folder options. Somewhat frustrating, as I'd rather have the empty drives showing, but it works.
