  1. Yes, there are just zeros in the last 9 blocks! To round up the image size make sense. I have checked a ISO generated by NERO, there the size of the iso-file is identical to the multiplication of 'Volume Space Size' and 'Logical block size' (and the size is not roundet to a multiple of 16 sectors!). Thank you very much!
  2. Thank you! 'Volume Space Size' (on 0x050, not on 0x080!) = 1175 (decimal) 'Logical block size' = 2048 (decimal) Volume Space Size is the number of Logical block in which the volume space is. So I multiply 'Volume Space Size' with 'Logical block size'. My ISO has 2424832 Bytes, the result of the multiplication above is 2406400 Bytes. That's a different of 18432 Bytes = 9 Logical block. Is this offset of 9 Logical block a constant overhead? Do you know that?
  3. Hi all, I have a question: Is there a way to read the byte length of the ISO-File in the header of the iso-file (e.g. Volume Descriptors)? I try to read a iso-File from a flash (embedded microprocessor), and for this I need to know how many bytes the whole file has. It would be helpful if I couold read the size of it from the ISO header on a defined address... thanks!
