Calibrating the LG WH14NS40 Blu-Ray drive

Calibrating the LG WH14NS40 Blu-Ray drive

Hi everyone,

I’m now at my 3rd LG WH14NS40 Blu-Ray drive. The first one had its Blu-Ray laser die and the second one began having issues reading Blu-Ray discs. The 3rd one reads them faster. But what if I could have fixed the 2nd drive? That’s what we will be looking here.

LG 14X Blu-Ray Writer WH14NS40 Drive Front

This drive is not one of my favorite writers. It is not a good writer. Most of the discs I burn with it ends up having the so called “donut rings”, and some double layer discs are not burned correctly. However, this drive is a good reader and is why I use it, that is, when it works.

When I got my 3rd drive, I opened it along with the 2nd drive, and tried to see the distance between a disc and the laser:

My 2nd drive had the laser more close to the disc itself, which may be why it was failing to read discs or take some time to read it. It was also making the grinding noises this drive is known to do.

The drive motor has 2 screws on the side which can lower or increase the distance between the disc and the laser, so by adjusting it, I was able to get the 2nd drive to successfully read a disc on its first try without the noises:

LG WH14NS40 Laser Calibration 4

This is a trial and error process. I recommend having a disc inside and move the optical pickup unit all the way to the back so you can have a better look. The optical pickup unit and the disc should have a distance approximately to this:

LG WH14NS40 Laser Calibration 5

Keep in mind that if the disc is too close to the laser, it may scratch the disc and you may hear loud noises when it spins the disc, as it may be making contact with it. Just try to make it look like the above picture and it should proceed to work right away. Of course, each optical pickup unit has its own calibration data, but this seemed to work just fine on my drive and has not had any issues ever since.

Now, my 3rd drive is only used just as a backup, for when this 2nd drive starts having issues all over again. It has to be noted too that this 2nd drive has lasted way more than the 1st one did.

If it still doesn’t work, or you prefer to get another one, you can get it on Amazon at the following link:

Burning the PlexDisc CD-R discs on some Slim IDE drives

Burning the PlexDisc CD-R discs on some Slim IDE drives

Hi everyone,

Today, we’ll see how well my 3 optical IDE slim drives handles the PlexDisc 700MB CD-R discs. The units we’ll be testing against this disc are the Optiarc AD-7561A, Teach DW-224E-C, and the Toshiba SD-R6252.

Toshiba SD-R6252

Let’s start with the Toshiba SD-R6252. You may recall this drive failed to burn successfully the Verbatim CD-RW some time ago.

The drive detects the disc just fine and gives us a burning speed of up to 16x:


Starting to burn the disc in “Test Mode” appears to be fine:

But ultimately gives errors when burning it for real:

Interestingly, the drive either thinks the disc is blank afterwards or can’t recover the Table of Content (TOC):

Result: Failure


Because the disc is reported as “Empty” on the Toshiba drive, I’ll give it another go. There’s 2 things that can happen here: The first one is that it actually writes the data, and the second one is that it overwrites already written data, making a junk disc. This disc, however, visually looked like there was no data written in it, therefore, I assume the Toshiba laser is worn out and does not have the required power to actually write any data.

ImgBurn is unable to report writing speeds on the Teac drive, for some reason:

PlexDisc CD-R on TEAC DW-224E-C Failed Burned Toshiba Disc 2

However, it can be written at up to 24x in this drive. Test mode was successful in it:

And so was the real burn, but it never actually went up to 24x. Instead, it stayed at around 17x:

Result: Success!

Optiarc AD-7561A

ImgBurn reports a maximum burning speed of up to 24x:

PlexDisc CD-R on Optiarc AD-7561A

Test mode was successful:

And again, so was the real burn:

Result: Success!

Quality Scans

Next, we’ll scan the discs on a variety of drives to verify how well they were burned.

Unfortunately, my Toshiba drive could not write them. However, the TEAC and Optiarc drives can successfully burn these discs flawlessly and provides good quality burns. I’d recommend this media for your data and music storage needs. It is very cheap and proved to work well on these old drives.

Burning a Verbatim CD-RW on some old Slim IDE drives

Burning a Verbatim CD-RW on some old Slim IDE drives

Hi everyone,

In this post, We’ll be looking at some Slim IDE drives and how well they work with a Verbatim CD-RW disc. The drives we will be seeing are the Optiarc AD-7561A, Teach DW-224E-C, and the Toshiba SD-R6252.

I started first with the Toshiba SD-R6252 which is the drive with the oldest manufacturing date:

This drive was manufactured on July 2004. In my tests, it seems to read DVDs fine, but it fails to read CD-Rs, often with an “Unable to Recover TOC” message in ImgBurn. This drive supports CD and DVD writing.

The drive detects the disc and gives us burning speeds of 4x and 10x:

Verbatim CD-RW 12x

I initiated the burning process at 10x. It was able to erase the disc, but was surprised at the following message it gave me:

Verbatim CD-RW 12x 11

For some reason, it thinks the disc is 0 MB. However, pressing OK makes the disc burn successfully, or so I thought. Turns out this drive seem to ignore ImgBurn’s request to cycle the tray, and when the verification starts, it just freezes and starts making seek noises. This drive was also the noisiest drive. It seems the laser makes some noises when burning. Ultimately, I ejected the drive manually by disconnecting and reconnecting the USB cable. Then, ImgBurn somehow say the disc is “empty” yet it shows the old Table of Contents of the disc:

Verbatim CD-RW 12x 2

Maybe the drive couldn’t handle burning at 10x, so I restarted it at 4x:

Verbatim CD-RW 12x 4

But again, it froze at verification:

Verbatim CD-RW 12x 3

The disc seems to be lightly burned:

IDE Drive 4

The result is a failure for this drive. It isn’t able to correctly burn these discs. But maybe it’s the drive that’s somehow dead for CD’s, since it has issues reading most of them but reads fine CD-ROMs.

My next attempt is to use my TEAC DW-224E-C. Here, initially the drive is unable to read the disc as the Toshiba drive corrupted it.

Verbatim CD-RW 12x 5

It does not let me do anything as it doesn’t read it. I had to jump to the Optiarc drive which was successful at detecting the disc and allowing me to burn it.

This unit was successful at burning and verifying the disc.

IDE Drive 10

You can see that the lighter burned area is now darker.

I then placed the disc in the TEAC drive where it was able to read and verify it successfully too:

Verbatim CD-RW 12x 8

It also allows us to burn the disc again, so even when it was written, I performed an erase operation first, which blanked the disc:

IDE Drive 11

And then fired the burning process:

Verbatim CD-RW 12x 10

It was able to burn and verify it too.

Verbatim CD-RW 12x 9

The final disc played fine in my new Oakcastle Portable CD Player, which states it can read CD-RW.


From the above drives, only the Toshiba SD-R6252 failed to burn it. Both the TEAC and Optiarc drives were able to burn and verify it fine. Maybe the Toshiba drive is bad, as it fails to read CD-Rs correctly, sometimes unable to read the Table of Contents and sometimes failing to properly seek. However, that same drive is able to read DVDs without any issues, so maybe the CD laser is bad.

For the TEAC and Optiarc drives, the final result is a working, playable disc. The Optiarc drive is able to burn these discs at 4x and 10x. I didn’t test burning it at 4x. The TEAC drive does not show the supported burning speeds on ImgBurn like it did for the other 2 drives, but in reality, it burns it at the expected 10x.

Philips BD-R DL 50GB burned at 6x on Pioneer BDR-2212

Philips BD-R DL 50GB burned at 6x on Pioneer BDR-2212

Hi everyone,

In my last post of the Philips BD-R DL 50GB discs, I shared the quality scan of the discs burned at 8x on the Pioneer BDR-2212 drive. Here, I’m sharing the quality scans of these discs burned on the same drive at 6x.

Overall, it is a good burn. As we saw in the previous post, it seems the drive manages to burn the second layer better. The LG drive, however, seems to have some spikes at the end while the LiteOn drive had more spikes on the first layer. The discs were all readable on both drives.

The burning took about aproximately 30 minutes, meanwhile the 8x burns takes about 25 minutes.

Philips BD-R DL 10pk

Philips BD-R DL 10pk

Hi everyone,

Today, we will be looking at the Philips BD-R DL White Inkjet Printable Blu-Ray Recordable media:

Philips BD-R DL 2

These discs were at a surprising price of just $9 dollars on Amazon, so I picked up 5 spindles of these.

Philips BD-R DL media

These discs holds up to 50GB and are rated to be burnt at up to 6x. Let’s take a look at the disc surface and label sides:

The discs have the Philips brand at the center of the disc. Also, we can see that the discs have some sort of tint on the data side. Hopefully, these will not affect the recordings. Or will it? Let’s find out how my burners handle these discs.

Burning on Panasonic UJ-260

My first attempt to burn these was with my old but trusted Panasonic UJ-260 drive. It has been successfully burning discs with media codes RITEK-BR2 (25GB), RITEK-DR3 (50GB), CMCMAG-BA5 (25GB) and VERBAT-IMk (100GB).

The disc was recognized as CMCMAG-DI6-000 and can be burnt at up to 4x in this drive:

CMCMAG-DI6 on U260

The disc was able to burn fine, but unfortunately failed verification. Let’s see the disc burned surface:

We can see that there are burning issues. The Panasonic UJ-260 writes double layer media in two zones. It starts at 2x, and then burns at 4x. On the 2nd layer, it goes from 4x to 2x. The red zones are when the drive spins down to 2x to burn the final parts of the disc.

Still, out of curiosity, somehow this disc was readable on the LG drive when I did a ScanDisc run on Nero DiscSpeed:

I burned another disc, this time at 2x. The burn again went fine, but the verification failed on the 2nd layer again.

Philips BD-R DL 7 Burned at 2x on Panasonic UJ260

The disc looks awful. You can see the rings in the recording surface. The scans also points this issue out:

Both drives agree that something is wrong at the end. The disc should technically be looking darker like the rings look, which would explain why the second layer was scanning properly until the rings started to appear.

Few days later, I burned another one at 4x using ImgBurn. The previous 2 were burned with Nero, but that shouldn’t had be an issue. This time, the disc burned and verified fine, but it still did rings at the disc surface:

Philips BD-R DL 7 Burned at 4x on Panasonic UJ260 Success

Scans looks better, but I wouldn’t trust the disc in its condition:

It’s still clear that the rings are affecting the burn.

Burning on the LiteOn iHBS112

I burned another disc on the LiteOn iHBS112. This drive is able to burn them at 4x and 6x:

CMCMAG-DI6-000 LiteOn iHBS112 ImgBurn

The disc burned and verified fine, but the drive produced rings on the disc surface too.

Philips BD-R DL 7 Burned at 6x on LiteOn iHBS112

This burner also burned this disc in 2 zones, one at 4x and the other at 6x. The first layer burned fine, but we can see it struggled on the 2nd layer at the 4x zone:

Regardless of the scans, the disc was completely readable.


This drive is interesting in that if I burn with Nero, it fails immediately with “Write Error” and closes the disc, effectively not allowing us to retry burning anything since it changes the book type to BD-ROM somehow. I tried with ImgBurn at 6x and it managed to burn and verify the disc, but again, it came out with rings:

Philips BD-R DL 7 Burned at 6x on LG WH16NS58 Success

The drive did seem to produce a better burn except at the layer break. Also, the several rings do have an effect too:

I burned another disc, but this time it failed verifying:

Philips BD-R DL 7 Burned at 6x on LG WH16NS58 Failure


It seems this time the issue is mostly at the layer break.


I have this slim drive, and surprisingly, it did not produce any visible rings in the disc surface. It is also able to burn it at 6x:

Philips BD-R DL 7 Burned at 6x on LG BP60NB10

The disc was verified successful too. Let’s see how it performs at the graphs:

The LG seem to tolerate the disc better than the LiteOn. The first layer scanned fine. In both cases, the disc was completely readable without errors.

Pioneer BDR-2212 (BDR-212ULBK/BDR-212M)

I recently got this recorder to try burning these discs and see if it would offer a better burning experience. It is able to burn these discs at up to 8x on this drive.

I burned some discs with Nero 2017, which I haven’t upgraded since that version since every version is essentially just the same, and it burned the discs fine at 8x.

Philips BD-R DL 7 Burned at 8x on Pioneer BDR-2212

The disc surface looks very good. No rings are present either. However, when I first scanned the disc with my LG drive, it gave a really bad result:

CMCMAG-DI6-000 Burned with Pioneer Scanned with LG

So I re-ran the test again and got a way better result:

CMCMAG-DI6-000 Burned with Pioneer Scanned with LG retry

The LDC numbers may look high but the BIS numbers are almost within the standards. High, but the disc works fine across all my drives. The above scan was also performed at 8x. Below, we have the scans from my LG and LiteOn drive, from the same disc burned at 8x:

As we can see, the LG drive scanned the disc better than the LiteOn drive, but it was read without any issues there.

This drive seem to have better results when writing the 2nd layer, which is unexpected. Usually, the 1st layer is the one that gets burned the best. I did noticed that this drive seem to do a power calibration when switching layers, which can explain why the LDC/BIS numbers are low at that point. I think of this because the drive seem to slow down and pause when it reaches the layer break. The drive then proceeds to burn the disc as usual. My other drives would just keep burning immediately at this point.


These Philips BD-R DL use discs from CMC Magnetics with media code CMCMAG-DI6-000. These discs seem to have compatibility issues with some drives. In fact, go to Amazon and read the reviews and you’ll see some people are also having issues when burning these discs. Unfortunately, drive vendors that update their firmware are low. LG and Pioneer seem to keep their drives up to date, but the LG doesn’t seem to have the best luck burning them, as some discs may come fine and some may fail. The Pioneer seems to handle them the best and can even overspeed it to 8x. I think the investment on the drive paid off. Considering these discs spindles can be found cheap now, I think I’ll keep purchasing them for my archival needs.

Pioneer BDR-2212 Teardown

Pioneer BDR-2212 Teardown

Hi everyone,

Today, we will be seeing a teardown of the Pioneer BDR-2212 Blu-Ray recorder. Like most PC Disc drives, a teardown is usually a very simple process.

First, let’s take a look at the drive itself:

Before attempting to open it, we must open the disc tray, so we’ll be able to remove the front faceplate:

Pioneer BDR-2212 Teardown 4

We will now flip the drive and remove each screw:

Pioneer BDR-2212 Teardown 5

And viola! We now have opened the drive:

Pioneer BDR-2212 Teardown 6

Its internals are very similar to most drives. You’ll find 2 small boards: One which holds the drive controller and EEPROM, and one that holds the tray loading mechanism:

Pioneer BDR-2212 Teardown 7

Here, you can take a closer look at both boards:

Now, lets take a front look:

Pioneer BDR-2212 Teardown 10

The internals are also very close to other Blu-Ray drives. In this case, the DVD and Blu-Ray optics are side-by-side, while other drives have this arranged in an up-down position. The LG drive, for example, have the Blu-Ray and DVD optics in an up-down configuration while the Panasonic drive also has a very similar side-by-side setup.

Pioneer BDR-2212 Teardown 11

On the left, we have the DVD optics while on the right, we have the Blu-Ray optics. The Optical Pickup Unit looks of very high quality. The motor is similar to other drives.

I hope this drive lasts a really long time. Internally, I would say each component looks very well designed, especially that Optical Pickup Unit. I’m still not sure whether to use this drive for CD and DVD burning, since that honor would go to my LiteOn iHAS524. It is, after all, capable of burning DVDs at up to 24x but burns most media at 20x when its OverSpeed setting is enabled. The Pioneer is able to burn up to 16x on DVD Single Layer media. I’m also not sure if the BDR-2212 is able to set the booktype on DVD+R and DVD+R DL discs, something that my LiteOn drive is able to do.

Another day, we’ll talk about how this drive handles BD-R DL media.

You can get this drive on Amazon at the following link:

Unboxing the Pioneer BDR-2212 Blu-Ray Burner

Unboxing the Pioneer BDR-2212 Blu-Ray Burner

Hi everyone,

This last week, I ordered the Pioneer BDR-2212. It is a Blu-Ray burner capable of burning up to 16x on BD-R, 14x on BD-R DL, 8x on BD-R TL (BDXL TL) and 6x on BD-R QL (BDXL QL). My reasons to get this drive are the following:

  1. Curiosity: Pioneer has been a maker of high quality drives, but comes with a high price tag. I already own an old LiteOn iHBS112 and LG WH14NS40 that I’ve crossflashed to the WH16NS60 and WH16NS58 (Which enables quality scanning).
  2. Problems burning and reading on the LG drive: The LG drive is probably the cheapest drive you can get now, but my first unit failed, so I ordered another one. The drive is also unreliable at reading and burning, sometimes making weird noises and burns have failed too.
  3. My Panasonic burner failed to burn CMCMAG-DI6 discs properly: The Panasonic UJ260 has been the drive I’ve been using to burn my discs and it has been working great, altough very slow sometimes, and can only burn BDXL at 2x. The drive works fine except for the CMCMAG-DI6 discs, which fails. We’ll talk about this on another post.

The Pioneer will be my main burner (assuming it can burn the discs fine) and reader from now on, and I’ll use the LG exclusively for 4K discs, since the BDR-2212 cannot read 4K Blu-Ray discs.

Let’s start with how the box look:

Opening the box, we can see the drive:

Pioneer BDR-2212 Unboxing 5

It came with a 100GB BDXL M-Disc:

Pioneer BDR-2212 Unboxing 6

Taking the drive off the box:

It also comes with the manual, Cyberlink suite and the mounting hardware:

Once in Windows, it is detected as a Pioneer BD-RW BDR-212M:

I’ll be testing this drive and see how well it performs. In my next post, I’ll perform a unit teardown.

You can get this drive on Amazon at the following link:

The OWC Mercury Pro 5.25″ External Optical Drive Enclosure

The OWC Mercury Pro 5.25″ External Optical Drive Enclosure

Hi everyone,

Today, I’ll show you the OWC Mercury Pro 5.25″ External Optical Drive Enclosure:

OWC Mercury Pro 1

This is an enclosure designed for Internal 5.25″ CD, DVD, and Blu-Ray drives. It uses a USB 3.1 Gen 1 connection to transfer files faster than when using USB 2.0. This mainly applies to Blu-Ray discs since they can have a very high transfer rate when compared to CD or DVD, hence having a USB 3.1 Gen 1 connection allows us to benefit by having faster transfer speeds.


The enclosure comes in a simple box where when opened, we see a box that contains the power and USB cable as well as the screws needed to mount the drive:

We then see the enclosure below:

OWC Mercury Pro 6

It comes protected inside a plastic bag:

Once we take it out of the bag, we can see the shiny metal enclosure:

Inside, we can see the board and SATA cables:

OWC Mercury Pro 12


I took out my LG WH14NS40 Blu-Ray drive from my desktop so I can use in the enclosure on all of my computers:

Installation was very easy. The drive was inserted and the screws were installed on the sides and bottom. The result is very nice looking portable desktop drive:

OWC Mercury Pro 19

Windows 10 detects it as Mercury Pro Optical and lets us know that it is connected via USB 3.0:

OWC Mercury Pro 20

So far, the enclosure has been working very great.

Now, I need another enclosure for my LiteOn iHAS524 drive, which is still my preferred drive to read and write CD and DVD.

Changing the LiteOn iHAS524 Optical Pickup Unit, again

Changing the LiteOn iHAS524 Optical Pickup Unit, again

Hi everyone,

Remember my previous post where I was talking about the LiteOn iHAS524 C and mentioned the different optical pickup units this model use across its different revisions? Turns out that the SF-DS1XD OPU used in the iHAS524 B was having trouble burning DVD+R DL, so I began my search for a used iHASx24 drive from the A revision.

On Friday, I got a used LiteOn iHAS124 A delivered. This model use the SF-DS19L OPU that all LiteOn iHASx24 use (x being a number from 1 to 6).

LiteOn iHAS124 - 524 1

The LiteOn iHASx24 series are all the same, except that the iHAS224, iHAS424 and iHAS624 has the hardware for LightScribe burning, while the iHAS124, iHAS324 and iHAS524 doesn’t. Other than that, the hardware is identical but they have different firmwares. The capabilities between models are the following:

  • LiteOn iHAS124: Base model.
  • LiteOn iHAS224: LightScribe.
  • LiteOn iHAS324: SmartErase.
  • LiteOn iHAS424: LightScribe and SmartErase.
  • LiteOn iHAS524: LabelTag and SmartErase.
  • LiteOn iHAS624: LightScribe, LabelTag and SmartErase.

Basically they have a different firmware enabling LightScribe, LabelTag and SmartErase depending on the model you have. Even if you have a different model, the firmware can be crossflashed by using some tools and firmware. I will not be covering that here, but it’s good to know if you’d like to add some features to your drives. The only feature that depends on hardware is LightScribe.

My LiteOn iHAS524 has been with me since 2010, and it’s probably the best CD and DVD burner available given its ability to overspeed 16x media to 20x. It also has HyperTuning, Online HyperTuning and SmartBurn, which are essential features to burn media with great quality. This is why I still count on this drive as sometimes I like to store data on optical media.

The drive had its optical pickup unit changed to the SF-DS1XD some years ago because one CD broke inside the unit, damaging the original SF-DS19L. I also didn’t use DVD+R DL media, so everything was fine, until last week. It turns out that the OPU had problems burning the discs. Specifically, it had problems focusing on the second DVD layer, failing at 50%. This is why I brought the used LiteOn iHAS124 A drive.

LiteOn iHAS124 - 524 3
LiteOn iHAS124 - 524 4

Because this unit is an A revision unit, the hardware between the iHAS124 and iHAS514 is the same. I did changed the iHAS524 disc mechanism to the one from the iHAS524 C revision, with the exception of the OPU:

LiteOn iHAS124 - 524 5
LiteOn iHAS124 - 524 6

On both photos, the iHAS524 is on the left while the iHAS124 is on the right.

Here we can see the disc mechanism from the iHAS124 unmounted:

LiteOn iHAS124 - 524 7
LiteOn iHAS124 - 524 8

And the Optical Pickup Unit taken out of it:

LiteOn iHAS124 - 524 9

I’ll be using this OPU in the original iHAS524 mount, so I placed it there:

LiteOn iHAS124 - 524 10

And finally, here’s the disc mechanism attached to the iHAS524:

LiteOn iHAS124 - 524 11

The OPU started working immediately. It is now loading discs faster and wasn’t making weird noises. I was also able to burn some DVD+R DL media without issues. I’ll be talking about that on another post, but for now, this is it.

The LG WH14NS40 Blu-Ray Writer

The LG WH14NS40 Blu-Ray Writer

Hi everyone,

On Saturday, I received the LG WH14NS40 Blu-Ray Writer Drive. This is my 3rd Blu-Ray writer and it will replace my LiteOn iHBS112 which was causing several bad burns. The other drive is the Panasonic UJ-260, which is a slim drive that burns discs successfully.

This drive is one of the cheapest Blu-Ray XL writers available on Amazon. It is also able to read and burn CDs and DVDs.

Here, we will see the drive unboxed and teared down.


The drive came in this simple box:

LG 14X Blu-Ray Writer WH14NS40 Box

There’s no branding. Just a box with the part number printed on a label.

Opening the box we see the drive:

LG 14X Blu-Ray Writer WH14NS40 Box Opened

Just the drive. No cables or software are included.

The drive is protected in bubble wrap:

LG 14X Blu-Ray Writer WH14NS40 Drive in bubble wrap

Also also comes inside a plastic bag:

LG 14X Blu-Ray Writer WH14NS40 Drive in Plastic Bag (Front)

Taking it off we see the drive itself:

LG 14X Blu-Ray Writer WH14NS40 Drive Front

Now, let’s take a look at the top, where we will find some useful information:

LG 14X Blu-Ray Writer WH14NS40 Drive Top

The drive is the WH14NS40, with SVC code NS50. It was manufactured on January 2020 and comes with firmware 1.04:

Drive Summary

This Blu-Ray writer can be crossflashed to the WH16NS60 16x variant. In fact, that was the first thing I did.

The drive is identified as HL-DS-ST BD-RW WH16NS60.

Here is the drive capabilities according to ImgBurn:

So far, I was able to successfully burn a BD-R with media code RITEK-BR2-00 and a BD-R DL with media code RITEK-DR3-000. Both discs were burned with ImgBurn and verified successfully.

Look forward as I test Blu-Ray media with this drive!
