ArchElf Posted January 12, 2008 Posted January 12, 2008 (edited) I have written an image yesterday with my new burner (you may remember, that I have to replace my old writer a few days ago), and a verification error occured. It seems that a bit error occurred (which is strange, since the coding on the disc should be able to correct several bit errors, and the additional CRC should be able detect more bit errors. But it looks like a single bit error occured, which were undetected by both the bit coding and the CRC, moreover with that bit error the disc still had the same MD5 hash as the image (with different data on it)... Verification in the other drive shown no errors. Sadly DVDInfoPro expired so I could not check the surface. Log below... AE I 22:43:14 ImgBurn Version 2.3.2.0 started!
