"Please insert a Disc into drive" Error

I have been reading a lot of these threads but couldn't find anything similar.
So i'll just explain the problem how it started.

I had to burn a lot of dvd's, and was burning 2 dvd's simultaneously using 2 different programs (Ashampoo and Imgburn), everything was going fine, I started playing Eve online a bit, 1st set of dvd's burned fine, continued burning them, 1 dvd burned fine, second one stopped with an error which was something like this:
xx:xx Burning Complete
xx:xx Burning Failed.
I was like wtf? After that error it started burning Lead-out and got stuck at around 30% for 5 mins, so i just terminated the process and the problem is as the topic states, with both drives.

I have 4gb ram and 2,4 ghz quad core cpu so everything should've been fine with buffer, it was at max all the time even while playing.
The device manager detects both drives and says that they are working fine.
Tried uninstalling the drives and restarting pc, problem still remains, so what could be the problem? And as far as it looks, it seems that both drives are dead just responding to actions open/close...

High eXefinity and Welcome to the Forum.

There could be stuff still being queued for burning.

Make sure you can see hidden files and folders, including the system, then GoTo > C:\Users\\Username\AppData\local\Microsoft\Windows\Burn\Temporary Burn Folder\.

See if there's anything in there waiting to be burnt.

Sadly it didn't work, even tried searching everything related to "burn" in appdata and deleting, and then uninstalling all programs related to dvd drives. Results are still the same. If it's not hardware related, then i'll try reinstalling windows tomorrow.

Have you tried completely shutting it down and turning it on again? Not just restart.

And have you actually put discs in the drives that are not blanks but are actual closed with lead-out just to see if it is recognizing any disk at all?

You mean by unplugging the hardware from pc? haven't tried that. Will try it in a min and report back.
About the discs, i've tried everything. Usually when you put a disc into drive, it starts spinning to read it, in my case, it does nothing at all

If they are USB DVD drives then yes completely unplug them and try plugging them in a different slot.

But no I was just hoping removing actual power would help.

Ok tried that, turned off pc, unplugged both data and power cables from both drives, booted up pc, turned off again, plugged both back in, and still the same

Now tried the same but left only one dvd drive plugged, still nothing :/

Do the drives show up in Drive Management? Maybe try unassigning the drive letters or changing the drive letters and then reboot?

EDIT: What I meant for Drive Management was opening Computer Management and selecting Disk Management.

In device manager? Yes they do show up under dvd/cd rom drives. And how can i change those drive letters?

edit:
ok nwm, found out what you mean, trying it now..
