  1. It was DVD43. I uninstalled it and now everything seems to verify OK. It looks like DVD43 was interfering with the bitstream from reading discs and was causing certain bytes read from the drive to appear to be 0x00, instead of their actual read value. It always happened at offset/byte 49 of a sector. So verify failures occurring regularly at offset/byte 49 of a sector with the drive reading the value 0x00 (as opposed to a can't read error) is indicative of this problem. Also, it only seemed to happen on DVD+R DL discs. Thank you all for your help.
  2. OK. Thanks. I'll remove dvd43. What is this pxhelp20 file? It seems to be some kind of legacy Sonic driver (my system came with sonic pre-installed, which I deleted - so this may be a few years old - I also installed winamp so it could be from there). Could this be the problem?
  3. OK. Here it is - =============================================== Filter Driver Load Order - ImgBurn v2.4.1.0 =============================================== Upper Device Filter: redbook Upper Class Filter: [None Found] Device: CD/DVD-ROM Device Lower Class Filter: ElbyCDFL Lower Class Filter: PxHelp20 Lower Class Filter: dvd43llh Lower Class Filter: ElbyDelay Lower Device Filter: [None Found] Filter Name: redbook File Name: C:\WINDOWS\system32\DRIVERS\redbook.sys File Version: 5.1.2600.2180 (xpsp_sp2_rtm.040803-2158) File Description: Redbook Audio Filter Driver Product Name: Microsoft
  4. I copied the image to a laptop and ran a verify with imageburn against the same disc on the laptop. It came up with no errors. Here's the log - I 22:58:41 ImgBurn Version 2.4.1.0 started!

Also, I have Alcohol installed (although it wasn't running but it has a resident virtual drive). I burned the same image again on the same system and I got the same error in the same location. Also I'm using CA anti-virus and security applications. The error always comes up at offset 49 of a sector and always reads the value of the disc as 0x00 - it never gets a can't read error. Also, it only seems to happens on DVD+R DL discs (never on single layer discs). I was using a patched Pioneer firmware to be able to use bitsetting on single layer discs, but I reflashed the drive with the original firmware before I burned the image again and I got the same error at the same spot. As there was no error on the same disc when it was verified by the laptop, it appears to be a problem reading the disc which always occurs at byte 49 of a sector, but only happens intermittently. Could an anti-virus program do this? Thank you all for your advice.
  5. You need better media - get some Verbatim, +R, 2.4x, MKM-001-00, Made in Singapore. Regards I'm not sure that's it. When I burn the same image again on another Ritek disc, I get the same exact error at the same exact sector. If it was just media, wouldn't it occur at different places randomly? also, it's not that it can't read the disc, it's that it always reads a value of 0x00 at that particular sector. Also, it always happens at offset/byte 49 of the sector.
  6. OK. Here's a log. I'll try to check it in another drive later - I 20:37:29 ImgBurn Version 2.4.1.0 started!

  7. I have the following problem - when I burn certain DVD+R DL images, I get consistent verification fails - the verification fails always show the device byte as being 0x00 and always seem to occur at offset 49. This only happens with certain backups and when I reburn I get exactly the same miscompares at the same exact locations. Since it always seems to show the device byte as being 0x00, I suspect that it's a problem that occurs in reading the disc, but one that does not cause a can't read error. I did have DVD43 installed, but I tried verifying with it off and I get the same miscompares. I have a pioneer dvr-115d drive and am using Ritek DVD +R disks. This error only happens occasionally, but as I said its is repeatable with those particular images. Also, the images have a set layerbreak. Any thoughts on what might be the problem?
