I have a Plextor PX-708UF (USB 2.0) on a Red Hat Linux 9 machine. When
I try to burn an ISO from either xcdroast or the dvdrecord command line,
I get the following:
============

The first Firmware from Plextor that is known to work halfway correctly
is 1.04.
Please first update the firmware, it is possible since more than a month!

=============
If this _still_ fails after you upgraded to 1.04, then there are two
possible reasons:
- A Linux Kernel bug - there are many of them.
- An unfriendly second application tries to do simultaneous
access.
A typical well known application is k3b from KDE.
In order to make sure this does not apply, boot into
single use mode. and try again.
The media is 4x DVD+R from Memorex. This is not an inherent problem
with the drive or media, since I can burn the same iso with growisofs.
If something is caused by buggy software outside the application,
then in many cases it may also work just by luck.
Xcdroast otherwise works (I used it to make the iso file), and it
correctly detects a CD-R (48x Memorex) when I tap ATIP-Info and it's in
the drive. I don't have DVD-R to test, but I will do that.
As DVD+R does not implement a simulation mode, it is recommended to
use a DVD-R or DVD-RW for tests.
Perhaps this is a firmware issue--I see there is a version 1.04
available for this drive. (I gather the 708A is basically the same
drive.) Can one upgrade Plextor firmware in Linux, or do I have to put
this on a Windows machine to do it?
Support for upgrading the firmware for the plextor 708 was added 2.5 months
ago.
