LIGHTNING UK!

Ok so from that log I can see your drive did actually report a 'Write Error' after that initial 'The request could not be performed because of an I/O device error.' one from Windows. In an ideal world, you wouldn't have ever seen that initial error and you'd have just got the real error from the drive to start with. That's where drivers (and filter drivers) etc come into play and mess things up. If your drive can't write to the 'GSC003' media at 4x without erroring out, give the other supported write speeds a shot. There are a few other things you can try too, but I'll get to them in another post. Do you have any decent quality discs from Verbatim / Taiyo Yuden? I've purchased a lot of random cheap ones in my time but I don't recall ever ending up with any using the 'GSC003' MID / dye. The fact 'Test Mode' works means that when the drive is instructed not to actually write to the media, everything else works fine. So it's just when the laser is active and it's actually trying to write to the disc. The commands sent by ImgBurn are identical (besides the 1 flag in a structure to enable 'Test Mode'). It can therefore only ever be the drive/firmware/media combo that's at fault here - even if you believe otherwise.

2x and 8x... what an odd couple of supported speeds! You'd normally always get a 4x in there too Have you tried at 8x? Real TYG02 discs are great, you should never need to burn them at less than 8x. If they're the real thing and both 2x and 8x fail, try cleaning the drive with a cleaning disc. If it still fails to burn them, with the exception of them being a faulty batch, you'd have to assume the drive is at fault. The drive/firmware/media combo are all that matters in getting a good burn. Software simply sends the data to burn, the drive has complete control over the burn itself.

No, you can access old logs via the 'Help' menu in the program. What I'd start by doing is updating your chipset drivers and put the v10.8 Intel Rapid Storage Tech. driver on (to replace that 9.2 version you're currently running). That's what I have on mine. Intel Chipset Software - http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=21594 Intel Rapid Storage Tech - http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=2101&DwnldID=20768 You want the 'STOR_allOS_10.8.0.1003.exe' one. Check your motherboard BIOS is up to date too as they sometimes update the option ROMs.

No, I need to see the stuff I asked for - i.e. the log from your failed burn. There are things I want to know / check before I give you any advice on what to do next. I'd also like to see the 'Family Tree' info. Right click the drive selection box and click 'Family Tree'. Close the prompt and then copy + paste everything from the Log window.

Try turning off the 'Online HyperTuning' option in the drive settings (Advanced Settings). Then use the 'Clear OPC History' option in the same place and try again. The 'Perform OPC Before Write' option made no real difference in my tests. I left it off in the end. Were the Verbatim discs made in Singapore? Check the packaging.

What would actually help here is to see a log file - as per the pink box up the top. If you've just installed ImgBurn, it's going to be running with the default settings. If in doubt, just his the 'Restore Defaults' button - that's what it's there for. You don't have to waste discs to test things out. You can use rewritables or DVD-R media (with 'Test Mode' enabled) until we figure out what's causing your machine to error out.

DAEMON Tools uses the SPTD driver, as does Alcohol 120% etc. Whilst I don't expect you to understand, the program can only peform as well as your system lets it. If it submits a command to the drive and an error is returned, that's out of my hands. The program just reports the error. If you've got CloneDVD installed, try switching to the ElbyCDIO interface on the I/O tab within the settings. It may be able to bypass whatever's causing Windows to report that error. I'd help you try and get to the bottom of the issue but I can't and won't do that if you think you know best and have already made your mind up.

Please post a log - as per the pink box up the top If they're BD-RE DL, you've probably got hardware defect management enabled or something (by formatting them with spare areas enabled). AWS doesn't mean anything (except 'MAX') unless you actually configure the AWS feature (look at the Guides forum).

Find them in that 'Local Users and Groups' bit, right click, select 'Properties' and then tick the 'Account is disabled' box. You should have been able to disable the 'Guest' account by just selecting it in the screenshot you posted in your first post and just clicking 'Turn off the guest account'.

Ok, so then I need to see the log of you creating the ISO file you later tried to burn. If you've done everything correctly, I can only assume the source files are to blame. ImgBurn just burns what you give it.

If you use something that makes use of the SPTD driver (and can't function without it), yeah you'll have to install SPTD again. Of course then the message will come back. If you don't have any problems with slow read/verify operations, you have nothing to worry about - just ignore the warning.

Click the 'Start' button. Right click the 'Computer' entry on the right (assuming you haven't removed it) Click 'Manage'. Confirm the UAC prompt if you get one. If you aren't using one of the more basic Windows 7 editions, you should see a 'Local Users and Groups' option in the tree on the left. (It's under 'Computer Management (Local)' -> 'System Tools') Under that you'll find a 'Users' group that'll contain all of the users on your machine. If you are using one of the more basic Windows 7 editions you probably won't have that 'Local Users and Groups' option. I don't really see the problem with just leaving them alone though. If the accounts are disabled, they won't show up on the log in screen and you'd never know they were there - except for when you go into the 'User Accounts' Control Panel app... and how often do you do that?!

It's probably due to commands failing or something weird happening as part of the virtualisation. Just ignore it.

Commercial Blu-ray discs are copy protected... you do know that yeah? If you try and read such a disc via the method you're supposed to use for copying a disc (i.e. using 'Read' mode and then 'Write' mode) you'd have seen ImgBurn tell you the disc was copy protected as you tried to perform the 'Read' part.

This is clearly a topic for the 'Chat' area and not 'ImgBurn Support'. Consider the topic moved. If the 'User Account' area won't let you remove the accounts, try the 'Local Users and Groups' MMC snap in (which you can easily access via a right click + 'Manage' on the 'Computer' entry in the Start Menu). Before doing so, you should probably Google the problem (again, as you failed to do it successfully the first time) to make sure you don't cause real problems by removing them. They're both disabled aren't they? As such, what's the problem with them being there? You'll never see them.

I see no log. In any case, this covers it. http://forum.imgburn.com/index.php?showtopic=8000

You're already writing at 4x, I don't think anything faster would actually work.... your drive will just error out during the burn or the disc will be unreadable.

There's nothing wrong with the speeds or time taken to burn/verify in that log.

It sure is

Going by this thread... http://club.myce.com/f44/what-drive-atapi-dh16ayh-233245 ...your drive is a Lite-On 165H6S. That would make more sense as it's far too old to be an Optiarc 724x one. Setting the layerbreak to '2133520' isn't physically possible with that drive, it'll just error out if you try. It won't cause a 'Write Error' though. The one you got with the BenQ drive was just because it didn't support the MKM-003-00 MID and couldn't write to the discs very well/at all. It's up to you if you update the firmware. I don't know exactly what changed with the newer versions but I typically always run the latest of everything. You can backup your current firmware easy enough using the LiteOn flasher tool from the MyCE forums and flash it back later if you don't like the newer one.

The firmware for your BenQ drive doesn't support the MKM-003-00 MID. The Lite-On looks like it does though... but you should put the latest firmware on it. http://www.firmwarehq.com/Lite-On/DH-16AYH/files.html I'm afraid I can't tell you that it'll work 100% perfectly, I have no control over such things. It's all down to the drive/firmware/media combo.

The 'ANY!' folder comes from AnyDVD and is nothing to do with ImgBurn. If it messed up when modifying the file system, I'm afraid that's out of my hands. Please examine that disc in IsoBuster. Once the correct drive has been selected, right click the 'UDF' entry in the tree on the left and select 'Folder tree and file information' -> 'List tree-info (in txt file)' -> 'LBA, Full Path'. Save the file somewhere on your computer and then upload it here on the forum.

That'll make the drive ignore what's in the firmware and build a new write strategy 'on the fly'. Be careful though... sometimes it works, sometimes it doesn't. When burning with the drive configured like that, burns are less consistent and because it's a drive setting (and nothing to do with the software you're using), it's applied to every burn you do and on all media.

This isn't an xbox forum. Ask on one of those instead please.

The drive says it only supports the discs at 4x and you can't make it do something it doesn't want to - it'll just ignore any request for an unsupported speed. Nothing about what you're burning can cause a burn to fail. So the file system etc don't even come into it. This is purely a drive/firmware/media combo issue.
