<br><br>My experience is too that hdparm -e is only for CD-ROM speeds, not DVD.
On some DVD drives that I tried I managed to slow it down using
speedcontrol:<br>
<br>

<br>
Not all drives support the SET_STREAMING command, but if they do then
it can silence noisy drives very effectively. For one drive I had to
upgrade it's firmware for it to support the SET_STREAMING command.<br>
<br>
After compiling the code you can add a line in the start-up sequence like so:<br>
<br>
/usr/local/bin/speedcontrol -x2 /dev/hdc<br>
<br>
to have the drive limited to 2x DVD speed.<br>
