Note: growisofs has code for that gesture but explicitly avoids to use it, if

the media was appendable before writing began. Instead it recommends to fill

up the media with zeros. This gesture nevertheless caused error replies from

the drives in my own experiments.
|
||||
The reason given by Andy Polyakov is that some DVD-ROM drives get mislead by
|
||||
the lead-out information of (formerly) appendable media unless the media is
|
||||
fully written.
|
||||
(http://fy.chalmers.se/~appro/linux/DVD+RW/ , "Compatibility: caveat lector")
|
||||
|
||||
Own experiments showed no such problems with PC attached PATA DVD-ROM drives.
|
||||
For best DVD-ROM compatibility one should avoid appendable media at all
|
||||
by closing them already after the first session.
