looking through my collection of log files these timestamps range from
[ 25381890 ] to [ 29665146 ], with or without modesty_on_drive=... does
not seem to make much of a difference. Maybe the time it takes for the
drive to become ready after closing the tray can account for this 4
seconds.

It's an internal drive, so the power supply seems to me like an unlikely
candidate.

Thanks :-)
And maybe the firmware programmers of the next drive were less
creative :-)
If someone here can report about experience (good or bad) with specific
make and models (still not sure whether the next drive will be a DVD- or
BD-writer), it would be welcome...
Thanks again, and have a nice day :)
