The disc can’t be burned, because the device failed to calibrate the laser power level for this media.

Unbelievable, the card and cloth actually worked for me. I've been searching forever tonight for a solution and decided to try that for the heck of it

Open System Preferences.
Click on "International"
Under "Languages": Drag any of the other languages to the top,
then drag English back to the top.
Set "Order for sorted lists" to English
Set "Word Break" to English (United States, computer)
Close System Preferences
Restart computer

what what what what what!?!
I really don't get it but that fix just worked on an 8-core, Macbook Pro and a Mini that all had the issue.

I'm dumbfounbded on several levels... why it works makes no sense at all, but how could you possibly figure that out? Blown away is all I can say... totally amazed...

The bizarre language changing procedure didn't work for me, but a business card and a lint-free cloth did.

Hi everyone. I got the "device failed to calibrate the laser power level for this media" too. I almost never use my macbookpro so it was a surprice. Anyway, this helped me:

updated firmware.

Burned at 2x speed. try different speeds, it helps.

Got it to work.

Good luck,

Ana

I have the same Problem but it looks no solution for it

Business card trick worked for me. I used a micro fiber cloth to make sure I didn't get a scratch or lint in the drive. Working great now.

this person is a brilliant one, I did this and this worked for me. A simple cleaning with a glasses cloth and a credit card did the trick. I also change it from English and back as recommended, but I think the cleaning may have been the fix, but both was done. I live 240 miles from the nearest apple repair so this solution is the best for those who live in rural areas like I do in bush Alaska. Thank you very much for posting.

Here's what worked for me after i got the error message I ran a CD played a couple of songs it worked fine , put in the blank DVD and it worked like new.
