Hi Chris
I have a similar burner to you, and it works just fine (Redhat 7.0, Adaptec
2940, P166/MMX) at speeds up to its rated 8x. See my cdrecord output below.
HOWEVER, notice your drive firmware revision. Mine is 1.07 but yours is
just 1.03. I think you'd better upgrade the firmware (from www.plextor.be
web site) as a first step. Then retry and report your results.
As always, make sure you have your SCSI bus properly cabled and terminated.
PS: What are the DIP switch settings on the back of the drive ? Mine is set
to 1 & 2 ON (up) and 3,4 and 5 OFF (down). Yours might be slightly
different depending on whether you have an external terminator or if the
drive is in the middle of your SCSI chain.

Subject: cdrecord mis-determines driver
Hi. I have a problem with cdrecord. For some reason, it won't set the proper
driver for my SCSI Plextor 8/20.
I'm sorry for all of the verbosity, but I don't know what is relevant. It
looks
to me like the error appears in the "mode sense g1" block, first with the
I/O error and then with the sense stuff (key, code, flags) - but am not sure
because these "errors" appeared on many newsgroup posts.
How can I go about getting the drive recognized? I have not seen anyone with
a
similar problem.
