Burn ISO to DVD9 and create ISO again don't give the same sha1 value

Recommended Posts

Hi there

Does anyone know what i have to change that the ISO will become the same sha1 value after burning (Write) on a dvd9 and then creating (Read) the ISO from the dvd9 again?

The ISO is over 5 GB. Does this even work?

Can't find something on google but perhaps i use the wrong search terms...

Many Thanks

Regards

Alitai

I just found out that when i doing it with Ultra ISO (Make CD/DVD Image...) then i get the same sha1 value.

This is very strange to me. Does anyone know why this happens?

Many Thanks

I mean the right sha1 value.

Can you post the log of the original burn too please?

It's probably to do with the size of the original image not being a multiple of 16 sectors - so it's then rounded up to 16 when you burn (the drive does that). That in turn makes the burnt disc look larger.

Okay now:

I did everything again. Ultra ISO did the Job right.

Original sha1: E448FD3CEB724A924A2AFCE17D80739329C30C74
After read with ImgBurn: C575298270C437810682E0188AB2A7B595F92E58 (Wrong)
After read with Ultra ISO: E448FD3CEB724A924A2AFCE17D80739329C30C74 (Right)

Hope you see something. Took a while todo.

Many Thanks for your Answer.

Yes, it's exactly what I said it was in my first reply. The source image size isn't a multiple of 16 sectors. Drive pads it during burn -> burnt disc comes out looking bigger -> read mode reads the full (bigger) disc.

Ahh okay. Thanks so much.

That means that you divide 1315487 / 16 = ‭82’217.9375‬

and there is nothing i can do about it?

Of course i can change the Image but i need the sha1 to be correct.

Math.... :rolleyes:

Thanks again.

Lovely Week

Alitai

P.S We need a ISO-Volume-Filter. Now i find everything on google because i know what i have to search for.

I 16:51:17 Source File: C:\Users\Test\Downloads\Win10_1809Oct_v2_English_x64.iso
I 16:51:17 Source File Sectors: 2’630’945 (MODE1/2048)

2630945 / 16 = 164434 remainder 1

So you're 1 sector into the next ECC block (a block of 16 sectors) and that's why your burnt disc shows up as having a size of 2630960 sectors. It's rounded up to the next multiple of 16.

Can you copy and paste all of the disc info from the box on the right when you're in Read mode and that burnt disc is in the drive please?

Edit:

I come to a break point of 1315488 for my ISO but this also doesn't help. It's the ISO which must be right. Now i get it.
