So what did you do *exactly* ? Describe your steps in detail,
and at what stage you concluded the disc was "ruined".

The table in the second article, appears to be referring to UDF

"Packet writing was introduced in Revision 1.50. For write-once media,
the entire disk is virtualized, making the write-once nature transparent
for the user; the disk can be treated the same way one would treat a
rewritable disc, but with steadily decreasing available space."
Lots of variables, and perhaps you could review your setup and
report back.
