try some verbatim discs. ritek is crap.

You should have a .dvd and .iso file. open imgburn and choose the .dvd file to write to disc.

Not sure what ultimately fixed me, but my old burner is working fine again. Woo Hoo! Saves me some $. I 21:58:51 ImgBurn Version 2.5.0.0 started!

The booktype is correctly set on his burn. OOPS. I scanned for it but missed it. Honestly couldnt even remember where it was in the log. Just trying to help. Good luck OP.

Never hurts to have a cleaning disc. If you are brave, disassemble the drive (usually a few screws) and clean the lens with a cotton q tip and alcohol. Also, I want to mention I have a DRU-830A that's never been used once, but been in a computer for about a year (server was seeing drive as DVD-RAM drive and it wouldnt read any disc we put in it), and I cant get it to burn the first disc. Apparently, being unused isnt any better, if it has been installed for a while it has still had wear & tear.

Perhaps you need to set the bookmark to DVD-ROM. Search the forum for instructions. Came across it looking for solutions to my own problems, thought it might help, but cant remember the process.

Sorry for double/triple posting. I tried something else with positive results. The original DVD burner connected to the computer with a USB adapter is able to burn and verify no problem. I'm wondering if something else I did while trying to get the Sony drive working, fixed the original drive. I did a bunch of stuff trying to get the DRU-830A to work. Among them, I reinstalled the drivers for my ide/atapi controller, because that was a suggestion in another thread for fixing the DRU-830A. I'm going to put the drive back into the computer and try again. Anyhow, here is the log from the last burn. I 20:31:40 Searching for SCSI / ATAPI devices... I 20:31:40 Found 1 DVD

Lightning. I understand what you mean. I have removed DVD43 completely from the system and tried again. Same problem so far. To elaborate on what I was asking. Why is it that when the other programs mentioned (dvdinfopro, etc) scan the discs that imgburn and abgx say are bad (wont verify), dvdinfopro says it is a good disc, and reports no errors? What is dvdinfopro checking? abgx and imgburn are verifying the disc against an image file, and reporting it as a bad disc, while dvdinfopro does some other sort of verification (never asking for an image to verify against). Since I last posted, I still have not been able to test the original drive in another machine. However, I have come across a Sony DRU-830A and installed it. I updated the firmware from SS20 to SS25, and although it seems to be able to verify discs with ABGX, it is having an issue burning DL discs. It is'nt showing that it is 'writing layer 0' and layer 1 like the other drive used to. Instead it just says 'writing track 1', and fails at around 4.9 billion bytes written, with the following error. Also, the drive seems to take a long time to read dual layer discs and it slows the entire computer down to a crawl when the disc is inserted. I 00:27:02 Writing Track 1 of 1... (MODE1/2048, LBA: 0 - 3825923) W 00:51:44 Failed to Write Sectors 2237344 - 2237375 - Reason: Write Error W 00:51:44 Retrying (1 of 20)...

DVDInfoPro scan of a bad disc is clean as well. I have to admit I am lost as to what exactly these programs are doing. I'm probably way off, but it appears that the disc is fine when verified except against the image. It's like imgburn is altering the image, maybe correcting it, when it shouldnt be.

According to this post http://forum.slysoft.com/showthread.php?t=27742 your burner is a rebadged Lite-On. That should make it possible to use a tool such as Nero DiscSpeed/Opti Drive Control/DVDInfoPro to do a quality scan of the disc. If you get terrible results - you know it's the burning phase (=burner/firmware/media) that is a joke. http://www.cdspeed2000.com/ Use 8x as scanning speed for the first two programs and 4x for DVDInfoPro. You get most accurate results that way. I'm not sure how to use the programs you told me about. I tested the media for CRC errors in DVDInfoPro and it came back completely clean (this was a disc that did not verify in imgburn). I am burning the test disc for opti drive now. The test disc in opti drive wont burn. It crashes opti burn... maybe because it isnt registered? I dont know. Windows screen pops up and says Opti Burn has encountered an error and needs to close, every time I try to burn the test disc. Even after a restart of the computer. But, I have it doing a disc quality check on one of the discs that didnt verify in imgburn. Another thing to mention, the discs that wont verify in imgburn come back as bad rips in abgx360 (while the image file used to burn them comes back all green), so it doesnt look like imgburn's verify is reporting incorrectly..

Sure. It will take me a little while to report back on that, since I would need to go to my Dad's house to put it into one of his machines.

Filter drivers: upper device filter redbook upper class filter none found device cd/dvd-rom device lower class filter pxhelp20 lower class filter dvd43llh lower class filter elbycdfl lower class filter imapi If that helps any. The only thing about the idea that dvd43 is the problem is that it has been installed since waaaay before I ever started burning with imgburn. And I have never disabled it in the past, even though imgburn gave the warning it has never broke anything, or interrupted the verify. It appears that the burn phase is what has gone sour. I was able to verify a disc I burnt a month or so ago, no problem. The bad part is that this burner has less than 6 months of use in my computer, so if the burner has gone bad it did so very quickly. This log info is from the gui, since this information doesnt show up in the actual log file, sorry if it doesnt look normal. I 04:55:45 ImgBurn Version 2.5.0.0 started!

Yes I did try it without dvd43 running. I havent tried disabling antivirus and burning a disk yet, but I'm not sure what difference that would make. I ran it again just in case anyway. Apparently imgburn doesnt produce a log for verification jobs unless it is attached to a burn, because it didnt record the verify information. I did get errors again, while DVD43 was completely closed. They are only miscompare errors. I am going to try to verify a disk that burned and verified successfully in the past, and try to narrow it down to either a burning issue or a verification issue. Also, I tried memtest. Let it run for 7 hours (left and came back). It reported 6 passes and 0 errors.

Im burning it now, will try it and post results. Hopefully Imgburn can burn it and verify successfully. It is rather small.
