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)?

Thanks.

You can try hdparm -i /dev/yourdevice

You may need to run this as root. There is a field for Serial
Number, but for my devices no serial number is provided. This may
not help you, but it could work.

Output from my system:

[EMAIL PROTECTED] ~]$ sudo hdparm -i /dev/hdc

/dev/hdc:

Model=Pioneer DVD-ROM ATAPIModel DVD-106S 011, FwRev=E1.14,
SerialNo= Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs
nonMagnetic }.....other info is there but is not relevant.

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.
