CyberLink Power2GO can perform 16x writing without problem.

Could you please copy + paste all of the disc info from the box on the right when you’re in Write mode with one of those blank discs in the drive?

Can I also ask how many discs you’ve actually tried to burn at 16x with ImgBurn?

It makes no sense that it should be burning at 12x. The fact it returns a speed value equivalent to 1.4x as the current write speed shows that even the drive thinks it should be burning at 16x. The blip at the start of the write graph could be where it’s deciding to burn at 12x instead of 16x.

I’m going to import one of these drives so I can have a play around anyway. I need an LG with this MediaTek chipset and I have ended up skipping the BH14 version as they still don’t appear to be available here in the UK.

Although still got “Write Speed Miscompare” message, the Drive burns at 16x successfully.

Imgburn can burn the Disc at 16x this time.

@LIGHTNING UK
The result at #1 may be caused by Disc’s quality. Sorry for any inconvenience this may have caused.


#8

I’m glad to see it working as I’d always thought it should do :slight_smile:

I’ll still get the drive because I want to see exactly where that 6400 KB/s (1.4x) reported speed is coming from. If it’s coming from the ‘GET PERFORMANCE’ command, that’s a bug LG will have to fix in their firmware. If it’s coming from the ‘MODE SENSE’ command (which I’d expect to wrap as the speed value is only 16 bits in size), I’ll want to know why it’s coming from there and not the ‘GET PERFORMANCE’ command - which should take preference.

The ‘write speed miscompare’ is essentially a cosmetic issue at this point (due to the above).

BH(WH)16 and BH(WH)14 are few of Drives which are not affected by ODC’s buffer issue on Create Test Disc over 8x speed.

Did anyone try to rip a bluray disc with this drive? What’s the ripspeed. I suppose it’s riplocked and cannot yet be removed. I’m building a new system and i need a new set of drives


#15

My BH16NS48 arrived today and having checked the response to the ‘GET PERFORMANCE’ command from the drive, I can confirm the following lines in the ImgBurn log are caused by a firmware bug.

W 00:15:26 Write Speed Miscompare! - Wanted: 71,930 KB/s (16x), Got: 6,400 KB/s (1.4x)
W 00:15:26 The drive only supports writing these discs at 2x, 4x, 6x, 8x, 10x, 12x, 16x.

It must be using 16 bits internally for the performance value when it should be using 32.

16x = 0x00011900 and the speed is being reported as 0x00001900, so they’ve dropped 0x00010000.

Command setting the write speed…

CMD b6 00 00 00 00 00 00 00 00 00 1c 00
OUT 08 00 00 00 00 00 00 00 00 ba 73 ff 00 00 69 60 00 00 03 e8 [B]00 01 19 00[/B] 00 00 03 e8

^^ notice the 0x00011900 being sent.

Command querying the current write speed…

CMD ac 14 00 00 00 00 00 00 00 01 00 00
IN 00 00 00 14 02 00 00 00 00 00 00 00 00 00 57 9d 00 ba 73 ff [B]00 00 19 00[/B]

^^ notice the 0x00001900 being returned.

The 0x0000579D is the initial speed (i.e. what it will start from before ramping up to 16x). It’s obviously not normal for a drive to slow down as it burns (except on mutli layer discs of course). 0x0000579D -> 0x00001900. :slight_smile:

Maybe LG will fix it one day?! I don’t know anyone at LG. If anyone else does, maybe you could mention it to them :slight_smile:

I’m going to attempt to implement a workaround so it neatens up the ImgBurn log.

I just tried it for you on a couple of double layer Blu-ray video discs I had handy… it got up to about 8x.


#17

Thx, and timewise? how long did it take?


#18

Approx 31 minutes for approx 43 GB.


#19

That’s decent enough. Oh and lightning. the research i’ve done into this drive seems to be consistent on multiple sites. They pretty much all claim this burner to be a 14x burner despite of the 16x indication in the name. The funny thing, not even the official LG sites list this drive yet


#20

That’s not surprising since both the 14x and 16x use the same chipset, MT1959UWDN. :slight_smile: LG (and others too) would rather have the consumer buy a new drive than upgrade/enable the feature(s).
