LIGHTNING UK!

This is probably where an autoloader would come in handy. I have a couple and used them when I was having to produce similar sized runs of school production dvds for parents. Using existing hardware though, I've never actually tried burning to multiple drives from an ssd. If it can handle it, and you'll know if it can because the buffer levels will be ok, you're fine to just open 3 instances and burn to 3 different drives. So really, just use as many ssd/hdd and copies of the ISO as required to reliably burn to 3 optical drives at the same time.

Correct, no headers or padding.

There's a specific number of sectors available on the disc. Each sector is 2048 bytes in size, so you can do it by file size alone.

Where it flips from one cell to the other. The number is visible in the preview window isn't it?

Check the autoplay settings within control panel. https://answers.microsoft.com/en-us/windows/forum/apps_windows_10-windvd-winpc/automatically-starting-dvds-in-windows-10/49cb607c-f93d-402d-a46c-59715cca8f36

Can you post the log please. There isn't much you can do if you've already tried a new drive and the new one is still failing to burn the discs nicely. Maybe you'll have to try some different ones. The cable shouldn't make a difference, no.

If that ISRC is wrong, it's because the drive is reporting it incorrectly. I can't see an issue with the rest of it. CDDA is only ever in one format, it can't be 'unknown'. Can you attach the CUE it produced please?

Post the log please

Sorry, no, there isn't.

Send it back and buy a new (not used) drive. There’s no reason to buy a used one really.

It certainly wouldn't be the first time that's happened, no.

If it’s failing to burn all dvds, you could try cleaning the drive with a cleaning disc (or manually if you strip it down). Failing that, buy yourself another one.

Post the log of you burning and verifying the disc please. Your original disc might be fine (before you messed with all of the settings), and that perhaps your playback device just has an issue reading the disc - hence why it stops early.

It burnt and verified ok, so if the iso was ok, the disc should be ok.

Can you post the disc info from the box on the right when you're in read mode with one of those discs in the drive please? If it's saying they're empty, there will be nothing to close. You'll have to find a drive that can actually read them.

Isobuster maybe?

The list of supported write speeds comes from the drive. It’s the list of speeds the drive claims to support for the media you’ve put in it. If you select a speed in ImgBurn that isn’t in that list, the drive will simply ignore it and pick the closest supported one. So if the lowest it says is 16x and you pick 1x in the program, the drive will burn at 16x. It has complete control over that and you can’t force it to burn any slower.

No, it won't cause any errors... unless of course your drive opts to use a speed that it's not good at burning at. So, your drive may support 4x and 16x on some discs. You pick 8x (which isn't an option) and the drive then decides it'll use 16x (rather than 4x). If 16x produces low quality burns, you should set the speed to 4x instead and hope that's better. If your buffer keeps emptying out, you have an issue somewhere. What can't keep up with the burner? It must be the source drive or the interface (if USB 1 or 2 etc).

Yes, Build mode makes data discs.

Maybe the disc really does have 4 tracks on it ?

Do not touch the Write mode option. It’s on auto by default yeah? Leave it as such or you’ll force the program to think it’s always burning a cd. Basically, the default settings are tried and tested. They’re what works best. ImgBurn always closes and finalises disc’s. There’s a guide for audio CDs in the guides forum. If it doesn’t specifically mention anything in there about settings, you’re safe to assume it’ll just work. Dao/Sao is always preferable to Tao, so that’s default too. There’s nothing in the gui that says if a disc was recorded in Tao or dao/Sao mode. I’m not even sure such a marker exists. Yes, disc and session state/status saying ‘complete’ means the disc has been closed. Opc before Write will make thing worse as often as it makes them better. If it was really that important to issue the command before a burn, the drive would do it automatically. So based on that and years of testing, it’s off by default. It’s entirely up to you if you want to enable it or not. Feel free to do so and scan your discs for burn quality, comparing the two results.

It's down the the drive really. ImgBurn can only go by what it reports. Put the disc in the drive again and copy + paste everything from the disc info box on the right when you're in Read mode.

If that's all it says every time you attempt to use it, and on multiple discs, I'd have to guess that some I/O command(s) are getting stuck being processed by the system. ImgBurn submits them and then waits for a response. Please try following the directions in this post and then provide the log. http://forum.imgburn.com/index.php?/topic/59-faq/?p=972

You can’t manipulate the booktype setting on pioneer drives. Either they do it automatically or they don’t.
