CD writing mode?

    A firmware update for our DVD recorder says it has to be written to disc
    'using disc-at-once mode and ISO 9660 CD-ROM file system format'

    When I right click on the file and 'send to... write these files to disc' it
    just writes them to the disc.
    How do I tell what mode it used?

    XP Pro SP3

    This is on a laptop that is unfamiliar to me - mine not having a recordable
    drive - so I'm not sure of the set up, but there is a little note at the
    bottom of the right click dialogue that says something like 'service
    provided by Roxio'. Would I be right in assuming that the required format
    is just the standard one, or would I need to seek out the default settings
    somewhere (I wouldn't be an administrator on the borrowed m/c).

    Cheers,
    S

    You don't want to be using the built-in IMAPI based writing capabilities
    of the OS.

    An ISO9660 file, is more than just a data file. it is an entire file system,
    complete with the sectors necessary to support booting on a computer. It
    is a miniature environment, all of its own.

    If you "Send to" a file like that, you'll end up with a CD with one file
    on it, "blah.iso".

    If instead, you use a program like Nero (payware) or Imgburn (free), those
    programs know how to take an image file, and convert it back into a piece
    of bootable media. There could be hundreds or thousands of files inside
    the ISO, and a proper burning program, will put all those files onto the
    CD for you.

    My guess is, the purpose of "Disk At Once" or DAO mode, is to do only
    one session on the media, closing the session when finished. It is also
    possible for optical media to support multiple sessions, like leaving the
    session open, and maybe the device you're feeding this to, won't like that.
    So Disk At Once, implies a one-shot recording, where the session is closed
    properly at the end of the write.

    Thanks Paul: an awfully complex business by all accounts!
    I'll scrap the 'sent to' one and start again.

    Cheers,
