Thanks for reply Ruben
but I still don't understand something.
you are talking about partition table which starts at 446. On offset 8 from 446 which is
$01C6 that you mentioned it should be value (4 bytes) of relative offset to partition
in sectors(LBA) but on that address I have four byte's value: 64 69 61 2E what is
2E 61 69 64 due to little endian system what is 778 135 908 decimal?!

Am I missing something?
