Hi, I formatted my computer and everything seems to be working properly. Thanks for your help. Thanks, bekky

Hi, The log file is too big and confusing because i have been trying so many things, but this is what has happened. The md5 of the file using FastSum is 7411CEE779D62FB82B64015C59B9862B and the Image MD5 from imgburn is 7514325a56dcdccad8bc8d47523b541b. When I write to dvd imgburn verifies the md5 and the logs show the Image MD5 and Device MD5 both match. When I run FastSum on the source file and the dvd file there is mismatch. If I open the imgburn iso and run FastSum on the source file and the file in the imgburn iso the md5 both match. It is only when I write to dvb that md5 of the file inside the iso is changing. I tried the same on another computer and the results are identical. thanks, becky

Hi, I tried everything you said and did the same on another computer with the same result. They are running xp and vista. I also tried it with the verbatim +r discs and the same problem. What else can i try? this is so frustrating Thanks, bekky

Has anyone got any other ideas how I can prevent this? Is imgburn faulty? Thanks, bekky

Hi, I disabled the antivirus software as well.

Hi, I ran Memtest86+ and there were no errors at all. I also tried to write the same file on a different computer and it had the same problem with the checksum. What else could this be? I have used dvd+r and dvd-r discs and this didnt help. I have wasted about 20 discs. When i copy the file to a usb drive it works and the checksums match. Thanks, bekky

Does this help? Thanks, bekky

Hi, I mounted and compared it and the hex compare matches. When I hex compare the written dvd file with hex compare these are the results. Thanks, bekky

Hi, The source file checksum is 7411CEE779D62FB82B64015C59B9862B and the written file checksum is 6C32DC3F1344A3A281985B0ACD662ADF. The log is below: I 23:00:25 ImgBurn Version 2.5.5.0 started!

here is the information after creating the image and then after is has been written to cd.

Hi, The fastsum image shows the checksums for the files. The first file is the checksum of the image before it is written. The second file which matches the first file is the original file source. The third file with a different checksum is after the file has been written. Is this what you wanted? Thanks, bekky

Hi, I use imgburn all the time to write to dvd, but when I try and burn downloaded trial software from adobe and write it to dvd, after I compare the checksums they are different. I can't install the software from the dvd because the checksums are different and get errors. I am using a Pioneer DVD-RW DVR-111D 1.29 (ATA) and from searching the forums I think the drive is adding padding or sectors to the DVD. How can I stop the drive adding padding or sectors to the DVD? Thanks, bekky
