I noticed that the drivers for my UL272 Bluray drive were created in 2006 and I'm wondering if anyone has managed to find newer drivers? My current read speeds seem to be locked at 2.1x although the drive information reports that it can perform at 4.0x.

fidelity101, there aren't new drivers from Microsoft, or others, and the speeds are usually determined by the firmware - which I haven't found an update for either. The speeds are based on the media you loaded.

There are information programs that can tell you the media info to look up the media speeds, and programs for benchmarking. I haven't needed to do this for quite a while, but here are some I have used that still seem active:

Nero InfoTool

You could sacrifice 1 or 2 disks for testing with benchmark programs to find the best speed / error rate.

Software > Burn > Nero DiscSpeed

Opti Drive Control is a program for testing optical drives and media.

Not sure if you want to go this far, but you could patch the speed info for your media, probably not worth it unless you have a couple of cases of media that you need to burn through.

MediaCodeSpeedEdit tool for DVD-Writers

Burner programs can sometimes set the maximum speed higher, but real throughput may not be affected, and errors will increase. Typically I would stick with the programs estimate of max speed which is tempered by success estimation due to write errors.

Buy better media :)

Please let us know how it works out and what tips you have based on your experimentation :)

Thank you for the helpful information! I was trying to read a disk to my hard drive and it was reading at 2.1x. I closed the lid half way thru and when I opened the laptop again 45 minutes later, it resumed and actually increased the read speed to 5.3x. I have no idea what the difference was but I'll have to keep experimenting. :)

I was copying to the D: and the drive didn't seem to be too heavily tasked so it must be a bug in the software or a settings issue I've yet to discover.

fidelity101, I have seen that too, its like it gets caught in low speed mode and won't spin up, nice find/trick, sleep and upon awake it goes faster :)

I thought Nero had stopped the downloads for the old tools, but they just changed the location, here is the direct link from Nero to download DiscSpeed and the other tools:

Thanks hmscott. I checked out that program and unfortunately it's imbedded with malware...something called PUP.optional.opencandy which is an annoying pop up engine that's almost impossible to get rid of once installed.

I'll reach out to Nero and see if they have a version WITHOUT junkware built in. :)

Also, I downloaded ANYDVD HD which is support to ignore the riplimit built into the drivers firmware, but it didn't speed up the copy process. My drive is the UJ272 and it's gotten up to about 2.8x but rarely does it go over 3x. I tried the same settings on my older UJ240 MAT ****A drive and it got up to 5.8x so it definitely has something to do with the specific drive. I couldn't find a firware update or fix for the speed issue but the drive never spins up very fast compared to the UJ2450 which is like a tornado. :)

If I get time later, I'll installed that Nero program in a hyper-v session (so I can undo the installation job later) and see if that increases the speed. If it does, at least I'll have an idea of how to adjust the speed on the drive.

fidelity101, if you've established the drive in the G751 doesn't meet your needs, then replace it. That's what I did with the G750JX, I installed a Blu-ray drive. My G750JH comes with a Blu-ray drive, and I don't burn disks, so for me it works.

I don't have a good recommendation for a replacement drive for the G751, it's a smaller form factor and the ones I usually suggest don't fit. When you find a good one, please be sure and post it here.

What I recommend for those with a larger burning need on the G750, is to use an external USB 3.0 burner. But, it looks like the G751 doesn't have a good USB 3.0 solution - it's stuck at USB 2.0 with Microsoft USB drivers - and the hack to install Windows 7 Intel USB drivers doesn't work with the G751 (works with the G750's).

The OpenCandy situation with Nero's downloads; good that you caught it before it went unnoticed:

What is this "Open Candy" junk? Nero Trial Software includes OpenCandy.

The first download I posted was to versions with/without Adware, you could use an older version:

Like I posted I haven't had a need for DVD burn tools in a long time; next time I will download / scan and check before posting.

Please let us know what you end up using to solve the slow burn rate.
