Need VERIFY option based on LBA in boot sector in ImgBurn Suggestions Posted February 5, 2008 · Edited February 5, 2008 by BitBasher This only happens when you burn to DVD+ format discs - yes they pad to the nearest ECC block (16 sectors). Hmmm, I have this happen when I burn (using ImgBurn) to a TDK DVD-R disc using a LiteOn SOHW-1693S drive. I also get this when I burn on my other LiteOn drive, but I don't have that model number. If you want, I can send you more information on the drive and/or media from the ImgBurn logs. ImgBurn shows you the MD5 + Padded MD5 when that happens (assuming the source image sector total wasn't a multiple of 16) so just make a note of it. I don't see two MD5 values on a verify (just the one), probably because I have a padded DVD-R disc and ImgBurn doesn't do this step with DVD-R. Maybe you can use something like IsoBuster to just read a certain range back to a file, it's not something I'll ever add to Verfiy mode. I have a workaround now, but it involves reading the disc to an ISO file, then truncating it's length (using HxD), then calculating the MD5. Takes time, but it works. I was hoping for a faster solution. Bit.
