According to block.c [1] it looks like:
- EndBlock holds 32 less significant bits of block address
- EndFile holds 32 most significant bits of block address
In that case both fields set to 0, point to beginning of Volumen. Do I
miss something?
As a side note, variable names were completely misleading to me :/
