Power calibration error can be caused by two basic things

1. Bad drive
2. media being burned.
Less often dirty laser lens.

Burning uses more laser power than reading so drive can continue to read while still not burning.
CDs and DVDs use different laser assemblies so one working is no indication that the other hasn't failed.

Did you change brand of blanks? If you are using store brand for example and even brands like Memorex you may get a different manufacturer of discs from purchase to purchase. Inexpensive media may have problems playing back smooth when you get near the end of the video (edge of Disc) too.

Imgburn for example can show the media information. http://www.imgburn.com/ do not install the toolbar by just clicking through the screens.[attachment=116515:imgburn1.JPG][attachment=116516:imgburn2.JPG][attachment=116517:ImgburnVerb.JPG]

The second image shows a cheap CD disc already used, The third image shows a good grade of Verbatim bought online since they disappeared from store shelves unused.

You could look at the ones that worked OK and compare to the ones that do not work now.

I've never cleaned the lenses on my burners going back to the original 2X CD burner or 4X Sony dru-500 when that came on the market.

I have had several drives that wore out and the first sign would be Power calibration errors and being picky on media.

Cleaning the laser lens I did try on my brothers drives. Usually it didn't help and where it did help it was from all the smoking he and his wife did around the computer. Did you ever clean the windshield of a heavy smoker and see the crud that had built up? that builds up on the laser too.

If you can substitute a different known good drive for testing purposes it'll probably work.

Hopefully you didn't press anything against the laser lens while cleaning as they need to be free floating so that mechanism can move them up and down to compensate for warpage and other problems.

From here: http://www.newegg.com/Product/Product.aspx?Item=N82E16827131038

This is my third one since May 2007

Pros: I can't complain about the quality of the burns.Every copy I've made came out Very nice.

Cons: You never know when it's going to stop working and your computer won't boot.My first one was "dead on arival" The replacement lasted less than three months.I'm on my third one now and we'll see how long this one last.Sooner or later I'll get a good one.


Don't buy this

Pros: After two firmware changes it finally reads a disc now and then

Cons: I have tried a few different brands of R+ and R- discs and it starts to burn and then stops. Coasters 100%. I have two other burners in theis machine and they do quite well. Don't waste your money.


Bad Luck Burner

Pros: Inexpensive price with a so-called reputable name brand product.

Cons: Product lasted less than a week when computer failed to recognize burner. Re-installed my old standby Plextor 8X and all is working fine now.


Still could be drive.

It didn't look like a very reliable drive from the user reviews. The old 4X Sony were great.
What Software are you using to burn?

I only use Imgburn these days. http://www.imgburn.com/ I believe it has an optional toolbar, Don't install it.
http://www.imgburn.com/index.php?act=screenshots

If you are using some other software. Try imgburn if not then..
The only one thing left to try is see if there is newer firmware.
Keeping in mind that a bad firmware flash will ruin the drive.


If an update doesn't do it I'm out of ideas.

[attachment=116592:imgburn firmware.JPG]

This is the easiest way I've found to check for firmware updates.
Other option is go to the Sony website.

Warning: A bad flash can ruin the drive. A Bad flash can also be using the wrong firmware.

Good Luck

Nero and Imgburn can coexist.

Imgburn shows it is failing at the Power calibration area of the Disc. Any blank disc has a power calibration area the drive writes to and then checks to see if it was successfully written to. I forget how many times that can be tried in total although it looks like Imgburn will retry 20 times.

As I understand it the software reads the disc and sets up the proper burn strength from the laser. Some discs need more power than others to burn. Such a disc will also shorten laser life. As the laser ages it may need to be set for more power to compensate for the weakening. Thus the power calibration test area. It will try with increasing power level up to max laser strength to get a successful burn and then it uses that setting to actually burn the disc. If the laser can not be ramped up in strength enough to burn the calibration area then you get the Power Calibration Area Error. This is my understanding of the burn process.

I use Imgburn for all my CD, DVD, and BluRay burning. I do keep Nero around for a few other things on this machine.

Maybe someone else can think of something but from the Imgburn log and taking into consideration the user reviews I read it looks like time to save for a new drive.

I used my old Sony 4X for 2-3 years until I killed it by buying 8X TDK discs and not noticing they had no mention of any slower speed. I theorized that the drive upped the burn power trying to burn them and killed the laser.

Sorry for the bad news & Good Luck
Roger

IME getting avoiding older drives, The reason for that is there will be fewer firmware updates which help with compatibility with newer media as it is released.

I've always had good luck with LiteOn. Currently In my main desktop I have a LiteOn DVDRW and a Pioneer BluRay burner. FWIW the Pioneer BluRay burner does a much better job than its predecessor LG did on BD-R discs (verbatim of course).

The computer I'm on here has LG DVDRW drives, They were free as pulls from broken systems. They all Work OK.

As with any hardware, Read User reviews.

Good Luck
Roger
