Problen with writing Twin Sectors

vbimport

#1

Hi
Please excuse my bad english.
Here is my problem:
I created a ‘BIN/CUE’ file with UltraIso,then i add 26 Twin Sectors to the end of file.
Then i append 3000 normal sector to the file.
For example this range
625 -> 650 , 651 -> 676 , 677 -> 3676
|| || |_________|
TWIN A TWIN B NORMAL SECTOR

Ofcourse i fixed the auxiliary field (ECC & EDC P&Q).

When i burn the BIN file with Alcohol (RAW DAO),result CD doesnt contain twin sectors and this range cannot be raed 3651->3676.
Why? Please help me.
Thanks.
