I will try to find the post stating what drives come inside both enclosures... I know I saw that on club myce, and it was related with some kind of issue with the capability to read UHD disks... That will take awhile eheheh

I use an Asus, that "shares" the same drive, more or less... I think the LG one is a newer Pioneer model, than my Asus... I'm very happy with my drive, the burns are awesome, and when a launch them on opticDriveControl (I use TSST Samsung to do so, because my Asus doesn't supports testing), it shows fantastic values. It's very good..

Yes, I thought so, too, but there's the https://www.lg.com/us/burners-drives/lg-BE16NU50-external-blu-ray-dvd-drive This one was said to be a Pioneer drive, as my Asus one, in Club myce forum... I'll attach a graph from one of the burns I did, that had oscillation on the verification... Yesterday I did two burns, and they didn't oscillate, but then again, they verify at 11,9x ASUS_BW-16D1H-U_A203.IBG

Isn't it weird that that kind of oscillation just happens whenever imgburn goes out of the maximum read speed allowed by the media? I only use Panasonic media, Japan import (MEI or MEIRA), with maximum read speeds of 12x (slowest 5x effective 12x). If the verification process keeps under 12,everything is fine, no oscillation whatsoever... But when it starts to oscillate, I get speeds of 16.9 or even 20x On the good side, my writing process keeps stable at 4.1, when before, here and there, I had values from 3.5 to 4x Burning the Nero, this doesn't happen... That's weird... But still m, your program is way better than Nero :-)

My Asus is an external drive... USB... As far as my own experience, all my burns made by it have better quality than the ones by Samsung... There's a couple of LG drives that are, also, Pioneer... As far as I know, there's nothing accessing the hdd... And yes, the black is a bit slower than the blue... The explanation given to me, by WD is that the "surface" of the disk consists in a single layer, and not in 2,like the blue one. That makes the disk, when full, a bit slower... What makes this disk better, is that fact that it is much more reliable than the others. But still, since the burns are alright, I don't worry to much... Just by curiosity, did you notice any thing wrong with my last log? Thank you for your help.

It's possible that for me, things are the same... Does your Pioneer driver's burning flawless? I ask you that because, the drive inside my Asus enclosure is a Pioneer burner... I knew what model it was, but I know that inside Asus Bw-16D1H brand, is a pioneer :-) And I confirm that the problem had something to do with the UPS... My TSST Samsung drive doesn't behaves like that, and if I disconnect the UPS things work as normal... So, I reconnect the ups, and since every verification I've made so far, turns out good, I rather not risk hardware failures, due to power surges... Unfortunately that happens frequently, in my city... Thank you, my friend

So, this is my last log, with debug mode on... I don't have any errors, but a lot of buffer entries... as I said, everytime a disk goes up the maximum supported speed (12x is the supported speed, but got lots of 16x verifies), the buffer goes up and down... I know that there's nothing to worry myself up, yet, but I would like to know what's really happening... Thank you all logdebug.txt

Just figure out another symptom: this only happens when while in verification against image mode, the burner tries to go up the maximum disk speed... for instance, if I'm burning a disk, it burns stable at 4x, but when verifying, a disk that has a maximum speed of 12x, the device verifies it at 16x... still, no errors... did another test, and disconnected the burner from my ups, everything went back to normal... so, it's perhaps, a question of power... ( I prefer to keep it on the UPS, just in case of a failure)

Ok, thank you... I'm not very worried, since in all tests I made so far, the burn passed with very nice values... But, just to be sure, I wanted to have another opinion... especially because this Asus burner of mine, just reached the 1000 burn mark. Thank you very much

First of all, let me start by saying this is an awesome software... Simple, smooth, very, very good. Thank you for all of your work. My question is, perhaps, a dumb one, but I'm curious, so I want to know a bit better. I have bought a BW-16D1H-U Asus burner, in December of 2017. The burner is very good, and I only use top-notch media (only Panasonic, high quality Verbatim, or M-Disc from either Verbatim or Milleniata - ok, and a couple of m-disc from Imation). The burner works fine, the burned BD-Rs work flawlessly, with no problems whatsoever... my question is, I had to change the HDD, and my power source. My old WD blue disc blew up, and so, I traded it for a black one (bigger warranty, more reliable) and an UPS, as a power source. This newer HDD is quite a bit slower than my previous one,but I didn't trade it because of speed, but because of reliability(this one is tougher than the older one). The disk is almost full, it's a 2TB hdd, with less than 100 Gb free, and I have almost 30 ISO files to burn. The burning goes perfect (I choose always the slowest speed), at 4x to 4.2x, without errors, and resulting in a perfect disc (with top quality, when verifying with Optic Drive Control, or any other verification software)...but what I now see, that I haven't seen before (at least, that I have noticed) is that, when verifying against the source ISO, sometimes the Image Buffer goes all the way down, reaching 0, and the Device Buffer goes up, to 90 ~ 99%... Still, I've got to say that the verification works smoothly, no errors whatsoever, no warnings, nothing that states that's something wrong with the burn. If I do a verification, without the "Against image" enable, I reach reading speeds over 12x, without any problem or movement in the buffer bar, and, I must repeat myself, there's nothing wrong. My question is: eventhough the write process works perfect, and the verification process works, also perfect, is that oscilation normal? Perhaps that oscilation is due to the fact that the HDD is slower than the older one? I guess "Image buffer" refers to the image file, ISO, so when the buffer goes down, could it mean that the HDD is acessing the ISO file with less speed than the reading on burner? Should I be worried with that oscilation? Or, like I've said, since everything's working fine, no errors in the log, perfect burns, constantly, with fantastic low error values in other verification software, is just normal behavior, and this is working as it should? I'm sorry for bothering you, and, once again, thank you very much, for your awesome work with this fantastic software... Best regards, to all ImgBurn.log
