Over the weekend, I had to make a technical support call on one
of my DVD burners, and at one point the recorded message
mentioned I should have my serial number handy.  I thought there
was a way to read that from at least one piece of software on the
system, but I couldn't remember one and man -k on a number of
subjects was unrevealing.

Can someone enlighten me (us)?

Mark: Try that! On my Desktop, it gives me the SN for the HD (hda),
but the space for
SN is blank, for hdc (DVD reader) and hdd (CD-RW). . If you are lucky,
on your box, it will give you the SN for the DVD
burner. Lanny
I don't think most optical drive manufacturers embed serial numbers in their
drives. Hard drives are different, as their testing process lets them change
something like a serial number, but an optical drive would require a custom
firmware to be created and then loaded to the drive. That would slow the
process.

That probably explains why when I tried it, there were no serial numbers for my
opticlal drives. I always see an SN for a HD, when running diagnostics on them.
Sounds like Mark is going to need to pull the bad DVD burner anyway, so when he
does, he can read the SN on the label and get an RMA for it.
I would have tried also, because now the system needs to come apart twice unless you just buy a new one and let the replacement be a spare.
