#1 How to find VAT ICB?

[Anonymous]

Can any one tell me how to find the VAT ICB location.
In the specification it is given as it should present at the
last sector recorded on the disc if it exists. But in some
cases I am not able to find the VAT ICB at that place.
By manually checking in "ISO Buster" I came to know
that it presents before some sectors from the last sector.

So please tell me how to find the VAT ICB address, and
what are the error recovery schemes to find the VAT ICB.
