What does it mean when the CD/DVD is blank no matter what?

I put known good CD data discs and DVD data discs in the CD/DVD
drive but on Windows D:\ just shows up as blank.

D:\ is definitely the cd/dvd rom drive.
The "device manager" shows it as "working properly".

Here are some screenshots showing this:

How do I test WHY the cdrom/dvd unit isn't reading data discs?

What do you see if you look at D: without _any_ disc loaded?

(How about an audio CD and/or video DVD?)

You might try cleaning the optics first.
If still no good then try burning a full disc and see if it can read that one.

Test the optical drive using another OS.

A Linux LiveCD is an option.

A clean install of Windows on a spare hard drive,
would be another OS to do the test from.

Chances are, the problem is a software problem
on the current OS. Like, an UpperFilter driver
that should be removed. And it's not really
a hardware problem at all.

Might have gotten out of alignment? Optical drives start getting like
that after a while, especially when they aren't used much anymore.

It could be that the CD/DVD in question isn't formatted as UDF
(Universal Disk Format) file system. Did you use some external DVD/CD
software package to create this disk? I am thinking of old Nero type
packages. They were terrible because disk created in one machine weren't
compatible on another unless you install a special program from them to
enable UDF on all machines on which you intent to use the disk.

Now this is from a Muslim Jihadist who has used DVD drives to distribute
bomb making instructions.
