    ImgBurn 1.1.0.0 Verify Fails But Nero Doesn't

    Alright, I tried the following : - disconnected Pioneer DVD-ROM drive and burned using only BenQ 1640 alone - no go - swopped BenQ 1640 for an LG GSA-4167B and used that to burn - no go - put the BenQ 1640 into another system on which ImgBurn verify has no problems - works So it is not the drive at fault. Whatever the problem is, I don't know. Getting kind of tired of it all.

    Overburn Benq 1640?

    Many DVD discs tend to be of crappy quality at the outer edges of discs. By this I mean the quality of the burn on the outer edges of discs tends to be worse than the rest of the disc. If you have a BenQ 1640 and have used Qscan, you will know what I mean. By overburning, you are actually trying to cram more data into the part of the disc which is of the worst quality! Secondly, discs tend to die from the outer edges inwards. You're looking for trouble if you try and put your precious data there. Many people dilberately avoid burning a full disc for these two reasons. They leave about 100Mb free at the ends of discs. Take it from a person who used to overburn CDs and lost quite a bit of data on them - it is not worth it.
  3. What cornholio7 is getting at is this : Memorex doesn't make it's own burners (or discs for that matter). Somebody made the burner for them and they just rebranded the thing. We need to know the real brand and model of the burner or else we can't help you. What you can do to find out what the real brand and model is this : 1. run Device Manager on Windows (I'm assuming you are using Windows 2k or XP) 2, open DVD/CD-ROM drives 3. look at the list of drives shown there - it should contain the real brand and model number of your writer

    ImgBurn 1.1.0.0 Verify Fails But Nero Doesn't

    I was using RICOHJPNR03 (proper Ricoh 16x DVD+R, not some rebrand) at first for these tests. Burn quality was beautiful (QS 99 in Nero CD Speed). The other thing I tested with was a piece of Verbatim 8x DVD+R (MCC003). Burn quality was good as well. Burn quality was again, good. I later switched to using Ricoh 8x DVD+RW (RICOHJPNW21) for these tests. These are all quality media so media should not be the cause. However, I'm not wasting my precious TY discs on tests! I have two other burners I can use for tests (LG GSA 4163B, LG GSA 4167B - I'm one of those people for whom burning media is a strange hobby) so I don't have to borrow a drive. That is a good suggestion though. I will try to swop writers and see if : 1. using a different writer on that system produces the same problems 2. using the BenQ on a different system causes the problems there Thanks for that suggestion. I suppose that is about the only thing left to try.

    That is precisely the version that I am using now. I was using the latest VIA 4-in-1 drivers but I switched back to the version on Asus' website. VIA Arena advises against using the latest version if you are using certain older VIA chipsets. I don't remember which chipsets exactly, but I do recall the KT133A being in that list. What I observed when using the latest version of those drivers is that my writer was less able to tolerate media which was of inconsistent quality. I'm talking about media with things such as high tracking error levels on certain discs in a spindle, and not others, rather than crappy media such as INFODISC or fake TY. With the latest drivers, burn quality upon burning with such discs resulted in awful scans or coasters. Upon going back to the version on Asus' website, it seemed as if the writer was able to tolerate those inconsistencies. No coasters and better burn quality. I tested this with two different writers on two systems, one of which is the above system, the other another KT133A system (which strangely does not have a problem with Imgburn's verify option. I know. I already changed IDE cables to a brand new set. No effect. I'm not totally sure about Pioneer, but I doubt anyone else makes drives for them. In any case, this is a rather old model dating from 2001. I doubt Pioneer subbed out drive manufacture then. BenQ actually makes drives for other people. The Sony DRU-810A is actually an OEM BenQ DW-1640. for instance. In any case, I tried making an image with DVDD using both the Pionner DVD-ROM drive and the BenQ writer. I doubt the Pioneer has anything to do with it. Same problem. What I can try is to disconnect the Pioneer totally and do a burn. I don't see why it would make a difference, since if it was the Pioneer at fault, Nero's burns would screw up too. The Pioneer does support UDMA66 (AFAIK, all Pioneer DVD-ROM drives and writers are UDMA66) but it will work fine on UDMA33. I have another Pioneer in different system running that way with no problems. The BenQ DW-1640 is a UDMA33 drive. There is a way to get it to work as UDMA4, but you have to cross-flash the thing with different firmware. Not going to do that.

    No, that was not a mistake on my part. This is explorer showing the image in question and the MDS file : Nero does not produce disc images of type ISO and MDS. The images it produces are in NRG format. The original disc that the image was made from, was probably burned using Nero. My guess is that that is what the logs are indicating. I don't know for a fact what program was used to burn that disc originally, because I wasn't the one who burned it.

    How did you figure that out from the filesystem? I definitely created those images with DVDD. How is it managing to report that the image was created using Nero?

    The images were not made with Nero. They were made with DVDD. I only used Nero to burn the images. No, they were not multipart images. There was just one single ISO file. DVDD created the MDS file by default.

    ImgBurn 1.1.0.0 Verify Fails But Nero Doesn't

    Ok, I've done a burn with verify and then used verify mode twice. The mismatch occurs at exactly the same sector and offset each time. I've also noticed that each time, the mismatch starts with the 5th byte of the lines of data that do not match. The 1st to 4th bytes match, but the 5th onwards do not. I am not sure if this means anything but I noticed the trend, so I thought I'd point it out. Attached are 3 log files, the first is of the burn with verify, the second and third are of the next two verification processes I ran. It's originally one log file but I chopped it into three to make it easier to compare. I did the same thing for the logs of the three burns I did above. Also, you will notice a time discrepancy from when the program was started and when I started the burn. That is because I did one burn and verify run, then realised I forgot to enable debug mode. So I had to do that again. I edited out the first burn and verify process from the logs, so that they do not confuse you. Hopefully this will be of some use to you. If there is anything else I can do, let me know. Thanks! ImgBurn.log ImgBurn2.log ImgBurn3.log

    ImgBurn 1.1.0.0 Verify Fails But Nero Doesn't

    Hmm, I didn't read this properly and did not realise you wanted me to verify the disc again in verify mode. I won't be able to do that for a few days because the system with this idiotic problem is currently packed away into a corner and disconnected. Space constraints in my room, unfortunately don't allow me to have that system setup and ready to run all the time. However, I did a few more burns and the verify errors happen in totally different and random places each time. Here are two more log files of two different burns of the same file as the one I used for the log I posted yesterday. Will try and rerun the verification part as soon as I can and post results here. Thanks again for all the help! ImgBurn2.log ImgBurn3.log

    lol, I think that if I try any harder, I will probably go insane. Amazingly enough, this is not the most frustrating computer thing I have had to do. That award goes to the time I spent 1 whole week installing and reinstalling WinNT 4.0 server (and all the service packs and patches) on an old Pentium II 400 which was faulty and locked up for no reason. Anyway, attached is the log file with debug mode turned on. Thanks for all the help from all of you. Much appreciated! ImgBurn2.log

    Ok, will go get that log file with debug data done. And yes, I have another system - the one I used to do CRC checks with CDCheck. That system has a different writer (LG GSA-4163B) and ImgBurn burns and verifies fine on that. The chipset on the motherboard is the same (KT133A) but it is a different brand of motherboard (MSI). I did not think that info was worth putting down, as I felt it might make things more confusing.

    Horribly old. One of them is 5 years old and the other is 4 years old. Fragmentation should not be a problem though, because I just installed the OS on that system from scratch in Aug. So that should account for the HD with my OS on it. The other HD is virtually empty. It's split into two partitions, both of which are 90% empty. It's main purpose is to hold disc images and process large video files. I did install win2k on one of the two partitions to see if my OS was causing the problem, but that is about it. Anyway, fragmentation should not be the cause of the problem. I wrote ISO files to both hard drives to see if the hard drive was causing my problems. Same result. Also, what I have been doing is to create an ISO image by reading a disc using DVDdec. Once saved, I used the same image to burn in both ImgBurn and Nero. If it was something to do with the image, harddrive or fragmentation, the burns with Nero should have failed verification.

    Nope. I don't have either of those installed on that system at all. Both the BenQ 1640 and the Pioneer 16x DVD-ROM drive are flashed with hacked firmware to RPC1. So I have no reason to use either of those two programs. I would need something like DVD Genie still, but I don't use that system to watch DVDs, so I have no DVD playing software installed.
  15. Hi, I'm posting here because I've pretty much tried everything I know. This is very detailed but I'll try to keep it short. I have a system which has an odd problem : burning an ISO with ImgBurn 1.1.0.0 always fails at the verify stage. By fail I mean a mismatch, not a read error. The odd part is that the same ISO burned with Nero 6.6.0.16 on the same machine produces a burn which is identical to the ISO. I don't trust Nero's verify option, so I've been using CDCheck on another system to do MD5/RIPEMD160 sums of both the original disc and the copy. I've run CDCheck on both the copies made by Nero and ImgBurn. The Nero copies always come out identical. The ImgBurn ones (which already failed ImgBurn's verify phase) are full of mismatches. What is worse is that I tried burning with DVDDec as well and the copies made also fail CDCheck's checksum comparison. I've been using DVDDec and ImgBurn for a while now, and evidently this has been happening all along. I just didn't know because until ImgBurn 1.1.0.0, the verify option did not do a bit by bit comparison. This is a brief description of my hardware : AMD Athlon 1200 Asustek A7V133 (VIA KT133A chipset) 512MB PC-133 RAM Primary channel : master-IBM 30GB 7200RPM HD, slave, WD 60GB 7200RPM HD Secondary channel : master-BenQ DW-1640 writer (BSLB RPC1 firmware), Pioneer 16x DVD-ROM (can't remember the exact model) WinXP SP2 I do not have any other DVD burning or region protection software on the system, apart from Nero 6.6.0.16 OEM which was bundled with my BenQ writer. No AnyDVD, no DVD43. I don't even have software to watch DVDs on that system. Discs used : Ricoh 8x DVD+RW (RICOHJPNW21). Also tried Ricoh 16x DVD+R and Mitsubishi 4x DVD+R This is a list of things I have tried which have not worked : Software : - installed a new version of ASPI from Adaptec and checked that ASPI layer was ok with ASPICHECK - set ImgBurn to use the system's own WNASPI32.DLL (installed above) instead of the standard SPTI - copied Nero's WNASPI32.DLL to ImgBurn's directory and set ImgBurn to use that to burn - shutdown every other application running in the background - disabled all services which were not needed (I even killed the print spooler) - disabled windows own ability to burn on my writer via explorer - copied the ISO to the other hard drive on my system and burned from there - reinstalled a fresh copy of the OS (Win2k SP4 this time) on a different HD and disabled all non-essential services - made sure both the BenQ writer and the Pioneer DVD-ROM drive were running at UDMA2 via Device manager - uninstalled VIA 4-in-1 IDE drivers and used XP's default - installed version 1.35 of VIA 4-in-1 IDE drivers - autorun is disabled Hardware : - ran MemTest86 to verify that my RAM was working properly - changed the IDE cable from a 66 wire calbe to a 33 wire cable - changed the power unit from a 300W power unit to a 350W power unit I'd post a log from ImgBurn, but I don't know that it would be of much help. I'll post any information or log files needed. Please, any hints would help. I am at my wits end.
