Hi Keiji,

Unfortunately I have never had the possibility to investigate such a disc 
|from up close.
The information always came via email and from people with less knowledge on 
the subject, so not always easy to assertain the real situation.
My guess in both cases was one (1) RZone, and not sure if the session was 
closed.

I think I see your point :
0xFFFFFFFF - 0x30000 + 2 = FFFD0001

I don't know how to explain the 2 but it looks like the drive gets confused 
then and assumes the last border starts at 0xFFFFFFFF (more or less) ?
Or that the last recorded sector number in the bordered area is 0xFFFFFFF 
(+2 ??)

Suppose I work around the issue,
what would be a good "faked" length for a single RZone disc (fully recorded) 
?

Best Regards,
Peter
