CD writing mode?
in [Windows XP]
|
From: Spamlet on 30 Jul 2010 21:30 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

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. http://majorgeeks.com/ImgBurn_d4870.html 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. http://en.wikipedia.org/wiki/Optical_disc_recording_modes HTH, Paul

I'll scrap the 'sent to' one and start again. Cheers, S
